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.

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

Irwin 28 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 !

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.

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

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.
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).

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.
