Scurvy

Irwin, is a brand of production boats much like Catalina and Hunter were in those years. The strength range of fiberglass was not known at the time so the hulls were overbuilt.

I had an Irwin 23. I had long since sold it but I learned to sail on it and the hull was indestructible.

Review of Irwin 27

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

CentreBoard

The Irwin 27 is equipped with a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can enter even shallow marinas as the draft is just about 0.81 - 0.91 meter (2.66 - 2.96 ft) dependent on the load. See immersion rate below.

The boat is typically equipped with an inboard Universal Atomic 4 gasoline engine at 30 hp (22 kW). Calculated max speed is about 7.2 knots

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Irwin 27 is 1.85, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.1 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Irwin 27 is about 110 kg/cm, alternatively 619 lbs/inch. Meaning: if you load 110 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 619 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is Displacement Length Ratio?

What is SA/D (Sail Area Displacement ratio)?

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 24m 2 (258 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

The Irwin 27 is a 27.08ft masthead sloop designed by Ted Irwin and built in fiberglass by Irwin Yachts since 1967.

The Irwin 27 is a heavy sailboat which is a reasonably good performer. It is reasonably stable / stiff and has a good righting capability if capsized. It is best suited as a coastal cruiser.

Irwin 28 sailboat review.

irwin 27 sailboat review

BTW - My 1970 IRWIN 30 leaked mercilessly at the deck-to-hull joint, found that the joinery was pointy screws which had worked themselves loose. Best practice is thru-hull bolting with nuts securing joint. [SAMUEL BURNS, Catalina 309 Southernaire, Alameda Marina CA]

Hi... I would like to ask if this boat(Irwin 28 mk ll)with the necessary Maintenance(bring up to date standing rigging, engine[new] New sails, and attention to old previous mentioned in this article Problems)would be capable to sail safely from Key West to Marina Hemingway, Cuba and from Fort Lauderdale to Bimini(Bahamas)? Your input would be appreciated. [email protected] Thx

Given the age of Irwin 28's, making a passage from Florida to Cuba/Bahamas will be more dependent on condition and the competence/preparedness of the captain and crew rather than the design of any one specific vessel. Having said that, I believe a properly prepared and maintained I28 would have no probably making either passage in light to moderate conditions. While she’s a good design, I would want a reliable weather window for crossing the Gulf Stream. If I were making a passage like this aboard an I28, I’d add locking mechanisms to the cockpit lazarettes to ensure they stay closed if the boat were to roll or get pooped. Also, replace the factory gate valves with proper seacocks.

a 28 would make the trip easy, my 31 used to make it all around the islands, she's a strong boat, and is built for sea crossings, billy 561-588-6222 www.floridaboatcaptain.com

I am a proud I28 owner.Great boat my wife and I love ours.Just big enough to feel safe and not to big so you can't handle her. I give the I28 a four STAR rating ****

Tommy - Thanks for reading and for the comment. I agree, the I28 is a great size and makes a nice family coastal cruiser.

Good to know, my wife and I just bought a 1976 Irwin 28 yesterday.

Congratulations! You'll love the I28.

Looking at buying one of these for Florida Coastal cruising.

Looking at buying one of these. I would be doing Florida coastal cruising on weekends. Your write up was very helpful, thanks.

Thank you! Your intended use (Florida coastal cruising on weekends) is exactly what the Irwin 28 was built for and excels at. Best of luck and let me know your thoughts about the boat once you've had a chance to try one out.

Irwins are better boats than many give credit for especially in the motion comfort and capsize ratio numbers. We loved our I32 sloop and she wasn't that slow as I out-sailed many newer model boats of equal length. If the boat is in good shape she can handle 25-30 knts winds with the accompanying seas well.

Forgot to mention sailed across Lake Michigan 80-100 miles many times so I can't see why you can't sail the 80-100 miles to Cuba from the Keys. Lake Michigan can be more treacherous than an Ocean due to the shorter wave lengths. I rather ride a 12ft ocean wave then get caught with 8ft LM waves.

Nice reading all the good stuff, and the other stuff I expected for an older boat. I saw one I28 where the hull/deck join was glassed over along the entire interior, along with some sort of core underneath the glass. I wouldn't think a core/pads would be needed, just a good fill and glassing over. I'm looking at one in two days, tiller model, with an A4. I'll be looking for soft spots on deck (ply core after all), signs of hull/deck leakage, and all the usual old boat stuff (leaking ports for example). Considering others (on other forums) sometimes say the Irwins aren't as good as say Pearsons, I've notice plenty of Irwins have coastal cruised safely as well as long trans ocean trips, which says many good things about the design(s) and the boat(s). Oh, the one I'm looking at is a CB model. I'm doing my research so to speak. Also, as a retired engineer/boat designer it's always interesting to read what owners of any boats I'm interested in have to say. After all, you folks know the truth about these designs, and have lived with the pros and cons for long periods.

Not sure if my last post made it on here. I have a 74 28'. I want to update the cabin and im looking for parts or ideas. The last owner did not keep up with the proper parts as I have plexie glass over my port holes instead of regular port holes. I want to restore this eye sore back into the beauty that she is and more. I was resently put out the army for combat wounds and this has become my oasis and stress reliever as I struggle with PTSD. I want to enjoy her for as long as she will float and could really use the help. Thanks James Watkins

I just aquired a nice Iwrin 37 MK I, (I think so.) I have been working in the vessel manufacturing business as a marine electrician with Northrup Grumman/hunington ingals; building ships for the US NAVY for 8 years and counting. Even though I helped build ships, I never owned one. So this in new for me. the Boat I have is in distressed condition as it was sitting for ten years. It needs complete rehabilitation. It was gutted before I got the boat. However, the wiring, ac/dc panels sinks and toilets/plumbing and also the engine remains. the bulkeads have been removed, and a post has been placed under where the mainsil mast sits.I want to get a bulkhead in there ( in fact wherever they are supposed to be) and get rid of that post as soon as I can but I need plans for this boat. (building plans.) IS THERE ANYONE who might be able to inform me where I can get this sort of information.wiring diagrams, plumbing layout, etcetera? I would be so very grateful for solid information. Thanks in advanced: DAVID

Try contacting Gene Gammon ([email protected]). Gene is a close friend of Ted Irwin and a former employee who now holds a lot of the historic info about Irwin sailboats.

In the event that its common Irwin construction I wouldn't go far......the hulls were dainty and the rudder support was assembled for calm bay sort operation...check the hull/bulkhead joints and you might wanna include a great deal of glass tape to hold them in.Normally plastic ports and casings that will break if hit excessively hard...a generally light built art.Irwin didn't assemble overwhelming boats.There was a second yard that manufactured the modest hulls,for the most part with a chopper firearm. -Kathy Hall.

I just purchased a 73 Irwin I have gutted the cabin and concerned about support for the mast inside the cabin. I'm not sure if there was something that is supposed to be in the cabin to support the mass

I've recently put my Irwin 28 sloop on craigslist - Mobile, AL. wiring,rigging,ignition system all new. It's been fun time to change.

I'm jumping in here on this conversation. I'm considering buying a I23. I know this conversation is regarding the I28 but does anyone have any thoughts on the I23 for a basic weekender?

This has been a very informative post and the thread that follows, too. I have owned 5 power boats over the past 22 years. living here in Florida. I'm looking to retire in the next few years and I always wanted to pickup sailing as a hobby. I will be berthing the boat in Fort Myers and already spoken to the harbor master at the downtown Municipal Yacht Basin. They have a 60 day waiting list for a slip. For the past several months, a 1975 Irwin 28 has been listed on Craiglist in Sarasota. It has no engine, but is equipped with an outboard mount, has tiller steering, roller-furling and needs a new cable for the swing keel - keel is in down position. From the scant photos of the exterior and the interior. The seller is asking 2400.00, but I am thinking 1500.00 given the work it needs based on his description and photos. This could be my weekend project boat to fix up, a learning boat for sailing and possible liveaboard on weekends while hitting the bars and restaurants within walking distance of the Yacht Basin. I would like some feedback on pricing and whether this is worth effort of restoration. Thanks in advance.

I have 4 sails for an Irwin 28.5 if someone interested [email protected]

Thanks for the great review. I've been looking at one of these over the O'Day, McGregor, Catlina, and other similar models as something to single hand. This is sort of a odd question, but is the same hull used in all model years of the I28? Sailboat data shows early 1970 models as 8ft beam, while later models have a 9ft beam (and some other different specs). I've noticed a few early models being spec'd with later model data when I look at them, but I haven't actually measured them.

I'm not certain, but yes, I do think the early Irwin 28's used a different hull. I believe there was a swing keel version initially.

How do you grease the gear chain for forward and reverse

I've read all the comments about the 28 . You've made up my mind I'm buying the 28 that I found . The atomic 4 is not running . But I need a project !

Irwin Yachts

Boats from designer/builder Ted Irwin were offered under any number of Corporate names, since, the company found itself in bankruptcy any number of times. Despite this fact, it was one of the largest sailboat producers in the US. Irwin himself, had an interest in racing and a number of boats he built were sucessful in that realm. Irwin also built many models specifically for the Caribean charter boat trade. The Irwin 42, 52, and 65 were among the most popular. The best information on anything to do with the builder, designer, and the long list of boats built by the firm can be found at the excellent Irwin Yachts website listed above. Owners manuals for some of most popular models can be purchased on line.

Irwin Citation 34

A mainstream coastal cruiser from an economy builder still managing to survive..

Irwin Yachts has been in operation for 27 years, one of the true old-timers in the fiberglass sail boat business. When we talked to them regarding the Irwin 34, they had just weathered the roughest storm of their history, having settled with their creditors and recovered from Chapter 11, when many other companies in similar situations were folding.

Irwin Citation 34

Irwin’s recovery was marked by the start of a new production 50-foot cruiser. The new boat, like all the boats throughout the company’s history, was designed by Ted Irwin, who has served continuously as CEO of the company as well as chief designer. In this respect, Irwin is like Catalina Yachts, whose CEO and chief designer Frank Butler is second only to Irwin in business longevity.

Like Catalina, Irwin has generally aimed at the economy end of the sailboat spectrum. However, unlike Catalina, Irwin Yachts has built a great variety of sailboats, 47 different models before their latest 50-footer—all sailboats, all larger than 20′, from all-out race machines to full-tilt cruisers. Among American companies, only Pearson comes close to Irwin in the variety of cruising sailboats produced over the last quarter of a century.

The Irwin 34 is in many respects a typical Irwin boat. It was originally called the “Citation 34,” which was meant to indicate that it was more of a plush cruiser than the race-oriented Irwins at the time, but more of a racer than the larger cruisers.

According to the company, 305 Irwin 34s were built in the production run, from 1978 to 1985, a moderate but successful model for the era. Near the end of its production, the boat was advertised as the Irwin 34 rather than the Citation 34. There were no major changes in the boat from beginning to end, just the details and equipment that are typical of any long production run.

Owners report mixed feelings in dealing with the company. Irwin dealers got good marks, though there are a few complaints about “incompetents and crooks.” The main objection over the years has been about slow response from the company, especially regarding warranty claims on new boats and getting basic information on older models. However, long term owners report that the company seems to have ups and downs in customer service.

Design and Construction

In design, the 34 looks like a cross between the old 1960s beamy CCA centerboarder and the mid-70s IOR racer, a combination that results in a moderate design and hence a healthy coastal cruiser. The bow has a distinctive concave curve, typical of many Irwin designs, and a flattish sheer, with a molded-in cove stripe to make the sheerline appear a bit higher in the bow. The stern sections have the peculiar tuckup typical of IOR boats of the era. The trunk cabin is traditional looking and fairly low. Overall, we think the boat is an attractive example of the modern racercruiser.

Underwater, the hull is beamy and saucer shaped. The centerline of the hull aft of the keel forms a shallow fence which runs back to form a skeg in front of the spade rudder. Though the boat was available with a deep fin keel, drawing 5′ 4″, the centerboard model was far more popular. Company literatureadvertises a shoal draft keel as standard, with the fin and centerboard as options, but we have never seen a shoal-draft model and none of the owners in our surveys had the shoal-draft version. Brochures show the shallow-draft keel as identical in outline to the centerboard model but with no board installed.

The centerboard lifts into a shallow stub keel, and the pennant is a Dacron rope; it runs to the deck through a tube which forms a grab rail at the front edge of the galley. We examined three used 34s, and the two centerboard models each had badly chafed centerboard pennants needing replacement.

Other than the chafe problem, the centerboard version of the boat is probably to be preferred if you have a choice. Unlike some boats which are designed for a fin and compromised with a centerboard, the hull shape looks well matched to the board, and few designers have as much experience with centerboards as Ted Irwin.

The hull is a conventional lay-up of mat and woven roving. The deck is a conventional balsa core sandwich.

The three boats we examined all had decent gelcoat and exterior finish, but owners in our surveys report an inordinate incidence of gelcoat problems, including patches coming off, large voids, and excessive crazing. One boat we looked at had quite a few repaired spots in the deck molding, and we suspect most of the gelcoat problems were new boat problems. Once fixed, they should not be a major concern for the used boat buyer.

Irwin Citation 34

With regard to other elements of construction, quality is on the poor side. In fact, the three boats we examined were serious contenders in our own used-boat search but were finally rejected because we didn’t like many details of the way the boats were built. For example, two of the boats we looked at clearly had a history of deck leaks at the portlights and a variety of fittings. The interior is generally well finished with teak-faced plywood and an interior liner, but the ceiling and liner made it very difficult to get at the inside of the hull and deck to trace or fix the leaks. It was clear that the previous owners had little luck in stopping the leaks. Further, the hull-to-deck joint is fastened with sheet metal screws rather than bolts. The screws are installed both vertically, from the top of the aluminum toe rail, and horizontally, from the side of the toe rail. Through-bolting is preferable.

More importantly, on the boat we were most interested in, it was evident that the hull-to-deck joint was leaking, at best a nuisance, at worst a major repair job. Though we couldn’t examine most of the joint because of the interior joinerwork, we did find one spot where the deck molding actually did not overlap the hull flange. You could see the underside of the toerail from inside the boat.

On one boat, the deck cleats were fastened only with sheet metal screws, and on all the boats, the bow and stern pulpits were only screwed down rather than through-bolted.

There were several details—cheap through-hull valves, no washers on chainplate bolts—which were relatively easy to correct, but they put us off the boat. Obviously, Irwin believes these construction details are adequate, but we consider them very minimal or problematic—something we would feel compelled to correct.

In contrast to the details, the basic fiberglass work seemed solid and good on all the boats we examined.

The interior of the 34 is generally well done, good production-line work with teak veneer and plastic. Some of the details of the cabinetry were a little sloppy on the boats we examined, but all in all the interior of the boat, when new, was undoubtedly a strong selling point.

There are three good berths—a V-berth double and a quarter berth. The quarter berth will be just a little tight, especially at the foot, for a large, tall man. The settee is usable as a single berth (it’s a very comfortable settee), and the dinette opposite is convertible to a small double. The head is of good size, and the galley is well arranged in a sort of wraparound U. There’s a good electrical panel at the aft side of the galley. The nav station is set at an angle, with the table a bit small though adequate.

The Irwin 34 came with seven opening ports as well as forward and midship hatches, so ventilation should be good.

Stowage below is minimal, since tankage occupies space below the berths—a shortcoming of the modern hull shape. Tankage is adequate on the boat—30 gallons fuel, 80 gallons water, and a big holding tank for the head—a rarity on production boats of this size.

There’s little bilge in the boat, which can cause problems when you take water inside the hull. This showed up in the discolored and delaminated teak/holly plywood on the cabin sole of two of the boats at which we looked.

Original standard equipment is quite complete and modern—hot/cold pressure water, shower, propane stove, 4″ cushions, AC and DC electrical systems, and so on, meaning that little upgrading should be necessary, assuming the boat has been well kept.

Overall, the interior seems very desirable for a couple cruising or a couple with one or two children. There are no privacy doors for the forward cabin, so two couples will have to be (or become) intimate while cruising.

The deck is conventional but well done for working the boat. There’s a deck-opening anchor locker forward, wide side decks, and a good big cockpit with a small ice/beer locker, two lazarettes, and a propane tank locker.

Irwin Citation 34

A wheel was standard on the boat. A nice feature is that a portion of the cockpit sole is removable for superior engine access, the best we have seen on a boat this size. Cockpit drains are also large, another rarity on production boats.

The companionway opening is large, with just a small lip/step above the cockpit sole. While not desirable in an offshore boat, this is okay in a coastal cruiser and makes for easy access to the interior. Most owners will want to arrange a way to secure the lowest companionway drop board, so it can be left in place during rough conditions.

The mainsheet traveler is on the cabin top, just ahead of the companionway. While this is a convenient location, the boats we looked at had exceptionally unsightly dodgers because the multi-part mainsheet was somewhat in the way.

Performance

The boat came with a Yanmar 15, which generally gets good reports from owners, though some think the boat is a bit underpowered. A 20-hp Yanmar was available as an option, and this would be desirable if a buyer were choosing between otherwise similar boats; the 20-hp model would be smoother running as well as more powerful.

The boat we sailed handled adequately under power, though some owners report it difficult to back up straight. Most of the 34s had solid props, and the performance-oriented sailor will want to upgrade to a folding or feathering prop so the boat’s sailing ability isn’t hurt.

The boat has a big rig, well balanced between mainsail and jib, and as you can expect from Ted Irwin’s design board, it is a good sailing boat. With a PHRF rating around 160, it is slightly slower than other cruiser/racers of that era, like the C & C 34, but it will make good passages, especially off the wind.

Many owners report that they consider the boat quite tender, especially the centerboard model, but we found the boat to be reasonably stiff, with lots of initial stability from the beamy hull. We didn’t sail the boat in heavy air, but we suspect an early reef would be desirable. Cruisers will find that it works well to sail the boat under roller-furling jib alone.

Early boats may have the DynaFurl roller which came as an option from Irwin, and buyers may want to factor in a replacement in their price figuring. The boats are generally of an age where the original sails are still aboard and, for all practical purposes, best used as drop cloths. Though the boat was advertised as a “club racer,” we saw no used 34s with spinnakers or any spinnaker gear, so a chute and related gear may also have to be purchased to complete a sail inventory.

Standard winches on the boat were minimal, and an upgrade will be desirable if the original owner didn’t buy the optional package when the boat was new.

The rig is adequate, the only problem reported by owners being paint problems on the mast, perhaps from a poor priming job on the aluminum. The mast of one boat we looked at had been re-painted.

Conclusions

It is an excellent design, a wholesome all-around racer/cruiser with shallow draft that would serve a family’s needs as a coastal cruiser, at a reasonable cost.

Unfortunately, the Irwin 34 suffers from some corner-cutting: details of construction which are cheap or shoddy, such as using only screws to secure the hull-to-deck joint.

Realistically, those details should not hamper the boat’s use in normal conditions as a coastal cruiser, but are substandard compared to many other boats available. We generally would not recommend the boat to anyone contemplating ocean passages, unless considerable basic upgrading had been completed.

But for a coastal cruiser, for an owner who likes to do some upgrading, the boat is a handsome, well thought-out design, with a good interior, well equipped. In today’s market, it offers a lot of basic boat, especially if bought at the right price.

Did the Irwin 27 have something glued . . .

  • Add to quote

to the inside of the hull? I am thinking about buying a 27'' Irwin. It looks like something was glued to the inside of the hull (carpet maybe). If it was carpet would anybody know what kind? Does anyone have an opinion of this boat? How can I get in touch with Irwin Yacht Co.? thanks, Yeto  

irwin 27 sailboat review

Boats of that era often had carpet or vinyl glued to the topsides. Most times it was a high grade automotive type carpet or else a foamed backed vinyl. I can''t recall what Irwin used on their boats. Irwin is no longer in business. Their boats varied pretty widely in sailing ability and most were pretty mediocre or worse in terms of build quality. Some of the Irwins were aimed at being race boats and were pretty competitive for thier day. Jeff  

The Irwin 27 is a great boat! I have never seen one with carpet glued to it but that is a fairly normal thing. My Irwin sails great and is tough as nails! It survived Ike with only a few scratches even though it ended up miles away and about 100 yards up a hill from the water.  

Irwin 27 IMHO what Jeff H said is not true of the early Irwins and certainly not true of my 1968. I sold, rigged and sailed many models as a manager of a dealership and generally the overall quality didn't decline until the price of oil went up.  

Irwin 27 any good info on the Irwin 27 ? I just got a 1968 & started putting some time & a little $$ in it but haven't sailed it yet.  

Irwin 27 Yeto. I have a Irwin 27 hull# 7. Great boat, VERY WELL BUILT.TAKES TEN FOOT LAKE MICHIGAN SEAS LIKE A CADILLAC. I THINK MY BOAT HAS HAD A LOT OF INTERIOR WOOD ADDED. THERE IS THIN CARPET IN THE V-BERTH. ITS COMMING OUT. AGAIN THEY SAIL GREAT! I LIVE ON MINE ALL SUMMER AND SINGLEHAND. PAINTED TOPSIDES AND DECK. IF I CAN HELP WITH ANYTHING I WILL.  

Irwin 27 My hull #is 1347 . I didn't know there where that many. It's very encouraging to here they are well built & take the seas well. I have started to sand the decks for some new paint & have the A4 running well. She was a lake boat (Lake Ontario) so I don't see any salt water problems. Any problems with the centerboard cables or pulleys or leaking? I haven't really got a chance to check it out but that cable has to come threw the hull somehow. Thanks Gary  

irwin 27 gcargen: My centerboard winch is on the floor in frount of the engin.The cable runs under the floor to a pully and back to a brass rod. The rod goes in and out dropping the centerboard,there is apacking on the rod,no leaks.I have seen the winches at the back cockpit and in front of it go figer. I had some window leaks I fixed. Did my none skid in kiwi grip great stuff.Just inspect everything,fix whatever and sail her .  

I have found the centerboard is stuck up in the slot. the cable going thru the hull is lose but it wont come down. I can see up into the slot & it's rusted & split out. Any Ideas on how to get it out? was it originaly just steel or is mine a replacement. When I get it out & clean it up should I just paint it or glass it? Any thoughts?  

gcargen: You may be able to get ahold of centerboard with a neadle nose vicegrip. work it up and to free it. Maybe run a thin flat knife like rod along each side to free it up. Good luck, waiting for spring.  

any info available on Irwin 28.5 ,bought 74 model , sound hull needs motor and sails everything else is there,is it worth the effort and investment  

Your discussion thread started in 2003. I think you will have to make the decision about the effort. Not sure what you mean by investment. If you mean for Resale or for your sailing adventure ? If you think its worth the time, work and money, then the whole project sounds worthwhile for you. I'm guessing you bought it cheaper than buying a sailboat that is ready to sail now.  

Re: Irwin 27 My centerboard has a slow leak when it is in the lowered position and I am clueless on how to fix the problem.

    It takes into consideration "reported" sail area, displacement and length at waterline. The higher the number the faster speed prediction for the boat.

  6. 1969 Irwin 27'

    Recently, I came upon a situation where a friend of mine would like to give me his 1969 Irwin 27. I know little about them, she is bare bones but seems built like a tank. High cabin top with almost an Alberg look to her minus the sweeping stern. Her sails are ok...no real appointments below...no electronics, stove...very minimalist and stoic.

  7. Irwin 27

    The Irwin 27 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a raised counter transom, an internally mounted spade-type rudder controlled by a tiller and a stub keel with a centerboard. It can be fitted with a spinnaker and displaces 6,600 lb (2,994 kg).

  8. 1967 Irwin 27'

    Irwin, is a brand of production boats much like Catalina and Hunter were in those years. The strength range of fiberglass was not known at the time so the hulls were overbuilt. Last edited: Sep 12, 2018

  9. Review of Irwin 27

    The Irwin 27 is equipped with a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters. The boat can enter even shallow marinas as the draft is just about 0.81 - 0.91 meter (2.66 - 2.96 ft) dependent on the load. See immersion rate below.

  10. Irwin 27

    The Irwin 27 is a 27.08ft masthead sloop designed by Ted Irwin and built in fiberglass by Irwin Yachts since 1967. The Irwin 27 is a heavy sailboat which is a reasonably good performer. It is reasonably stable / stiff and has a good righting capability if capsized. It is best suited as a coastal cruiser.

  11. Irwin 37

    Deck Layout. The Irwin 37 is a handy boat to sail. The sidedecks are wide, the rail rises to a low bulwark forward to give a sense of security and the cockpit coaming has an opening to starboard but is low enough to climb out of anywhere. The bowsprit is designed to carry a 30 lb plow anchor housed in a roller chock.
