Sirius 21/22
Sirius 21/22 is a 20 ′ 11 ″ / 6.4 m monohull sailboat designed by Hubert Vandestadt and built by Vandestadt and McGruer Ltd. between 1977 and 1987.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Vandestadt & McGruer was the Canadian importer of the American built MacGregor line of trailerable sailboats in early 1970s. The company also built the SIREN 17. The SIRIUS 21/22 is said to be the first North American production-built, ballasted cruising boat with positive flotation. In a more expensive procedure, closed-cell foam was injected into some compartments, then into the gap between the inner and outer hull the full length and up to the deck level. In the early 1980s, the hull was modified to include a reverse sheer transom at which point the boat was renamed the SIRIUS 22. A fixed-keel model was also offered.

Review of Sirius 21
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 Sirius 21 is equipped with a swing keel. A swing 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 0.40 - 0.50 meter (1.31 - 1.61 ft) dependent on the load. See immersion rate below.
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 Sirius 21 is 2.51, indicating that this boat would not 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 5.8 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 Sirius 21 is about 92 kg/cm, alternatively 517 lbs/inch. Meaning: if you load 92 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 517 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 a Ballast Ratio?
What is Displacement Length Ratio?
SA/D (Sail Area Displacement ratio) Indicates how fast the boat is in light wind: - Cruising Boats have ratios 10-15 - Cruiser-Racers have ratios 16-20 - Racers have ratios above 20 - High-Performance Racers have ratios above 24 Sail-area/displacement ratio (SA/D ratio): 20.37
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 17m 2 (182 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.
If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
| Usage | Length | Diameter | ||
| Jib sheet | 6.4 m | (21.0 feet) | 10 mm | (3/8 inch) |
| Genoa sheet | 6.4 m | (21.0 feet) | 10 mm | (3/8 inch) |
| Mainsheet | 16.0 m | (52.5 feet) | 10 mm | (3/8 inch) |

Sirius 28 information? Anyone?
- Add to quote
I'm in the process of researching and choosing my first sailboat. I'm on Lake Ontario and have time off each summer for extensive cruising (Where to? Could be anywhere). I want the boat to sail well - first and foremost it's a boat - and if it was bluewater capable then all then better (dreaming...), and I might also live aboard (I'm a bit of a minimalist so a large boat isn't essential for that). I've considered many boats including the Grampian 26, Albin Vega 27, Tartan 30 and others, but the Sirius 28 keeps coming to my attention. The problem is that I can find very very little information on the Sirius 28. From a distnace it appears to be comparable to the Tartan 30, but I don't really know because I can't find much information on the Sirius 28. Does anyone have information about the Sirius 28? Sirius in general? Thank you. Kevin MacTavish

(519) 372-9767 Box 7 (519) 371-3999 Owen Sound Ontario, Canada NYK5P1 Sirius sailboats (21’ 22’ & 28’) were manufactured in Canada during the early to mid 1980s. This Article below was featured in Canadian Yachting, June 1986. Sirius 28 Good breeding and "modern conservative" thinking produce a reliable , appealing cruiser By Paul Howard If the Sirius 28 was a racehorse, it would be described as having good breeding. Its designer, Hubert Van de stadt, has in his stable the smaller Sirius 22, a restyling of his Sirius 21, which has proven to be a tough, able, small cruiser. This talent for design runs in the family. Hubert is the nephew of the well-known European designer E. G. Van de Stadt, who has a long and impressive list of outstanding designs, including the lines of the famous 72-foot South African ketch Stormvogel. The Sirius 28's builders also inspire confidence. Vandestadt and McGruer Ltd. of Owen Sound ahs been building boats since the mid-'60s and in spite of such setbacks as major fire and a long industry recession, it has managed to survive and grow. With this kind of bloodline, the Sirius 28 is creating more than a passing interest. The first boat was launched in August, 1982, and as of March 1986, the company had orders booked through to hull 90. A 'modern-conservative' design The design is "modern conservative." The "modern" comes from the systems that make sail handling more efficient. Inboard shrouds, inboard sheeting, slab reefing with internal lines, sheet stoppers and internal pre-stretched rope halyards led back to the cockpit are examples of the designer's solution to the problem of simple, efficient sailing. The long waterline, fin keel, spade rudder and sharp entry are becoming standards in yacht design. The four-foot, four-inch fin on the Sirius 28 is a lead keel of 2,600 pounds. This gives her a ballast: displacement ratio of almost 40 per cent. Combine this with a beam of nine feet, eight inches, which is carried well aft into the quarter, and you have a hull that is able to stand up to her sail area of 410 square feet. Vandestadt and McGruer In their desire to expand the boat's market into some areas on Long Island Sound where the water is particularly shallow, Vandestadt and McGruer is attempting to decrease the draft without hurting sailing capabilities. To this end they had John Hemingway design a winged keel for it. Hemingway has been involved in keel research and design for the True North America's Cup effort. The winged keel has the same displacement and center of effort as the fin. The idea is not to improve sailing ability, which is fine, but to decrease draft to 3 1/2 feet while maintaining performance. The masthead single-spreader rig supports a Cinkel deck-stepped mast. Single lowers are helped out by a baby stay or jack stay to prevent mast pumping. The chainplates are inboard, which allows inboard sheeting of the headsail. This will help the 28 get weather efficiently. An outboard chainplates also make movement fore and aft much easier. It's not necessary to duck under the lowers on your way up to the sharp end. The boom is controlled by a traveler running the width of the cockpit just forward of the wheel. This provides an excellent sheeting angle, making mainsail trim easy and efficient. The self-bailing cockpit has no bridge deck but a high sill will prevent any water getting below in the event that a sea sneaks aboard. High coamings, two large lockers and excellent visibility forward make the cockpit an enjoyable spot. It is long enough to let you sleep out in nice weather and the boom comes far enough aft to rig a simple boom tent or sun awning without the topping list splitting it in half. Test sail Well, now that we know the deck layout, let's go for a sail. Close-hauled, the wind puffed up to about eight or nine knots apparent. In this light stuff and a smooth sea, the boat slips along with very little fuss and its efficient high-aspect rudder provides good control even when drifting. Under these conditions, the Sirius 28 is very close-winded, tracks well and accelerates nicely in and out of the puffs. Even downwind it ghosts along under a main and number-one Genoa, leaving hardly a ripple in its wake. While we are not too busy, let's look at the rail stanchions. The base and stanchion are one-piece assemblies. This produces a strong fitting as do the bow and stern pulpits of one-inch welded tube. They are through-bolted to solid glass areas in the foam-cored deck. Standard double lifelines enclose the deck. A stainless steel boarding ladder built into the stern pulpit completes the deck details. Teak treads on the ladder would be kinder on bare feet than the stainless tubes. The molded toe rail on the deck edge is fairly small in section. When the rail is buried and the spray is flying, I wonder if the toe rail would provide a sufficient toe hold. It seems to me it would be pretty slippery. A bow roller and self-bailing anchor locker make easy work of retrieving and stowing the anchor and rode. Down under Well, we've sailed into a hole, so let's go below and snoop around. Opening ports-eight standard opening ports! Once you have cruised on a boat in the tropics, you will never sail without them. The cross-ventilation they produce can make the difference between roasting and rapture. Wide beam and high freeboard, along with a fairly high trunk cabin, result in a lot of hull volume. This has allowed the designer to locate an enclosed head compartment aft on the port side. A one-piece molding comprises the sink vanity, with stowage under the sink. A foot pump supplies the sink from a 20-gallon water tank complete with an outboard vent and deck fill. The galley is aft on the starboard side and includes an alcohol stove, an icebox and a single sink with a foot pump. Propane cooking is an option. Put your money down: you won't be sorry. Propane is cleaner, faster more convenient and cheaper. Just stay afraid of it and follow all the safety procedures. If you do go for a gimbaled propane stove with oven, a safety bar across the front of the stove would provide a safer work area for the cook. A full interior liner makes a neat job of the overhead surfaces and good head-room extends right up into the V-berth area. This is accomplished by extending the trunk forward and not fading it into the deck. It doesn't look as streamlined but it is a compromise the designer felt was justified. The hull is lined with a closed-cell foam called Ethafoam and covered with a rich-looking fabric. It has good insulation qualities, looks attractive and, when it wear, it can be peeled off and replaced. The standard cabin sole is carpet, but a teak and holly sole is available as an option. A dinette on the starboard side, which converts to a double, and a settee on the port side complete the seating. The table slides up and down the mast compression post and it is a simple matter to move the table down to make up the double berth. A folding chart table above a hanging locker completes the interior. The teak joinery work below and on deck is well executed. Stowage is ample. The iron genny I don't hear the bow wave chuckling, so we must be out of wind. We fire up the two-cyclinder 18-hp Yanmar and it raps away at idle. I have noticed that these engines have a fair bit of combustion knock at idle, but once they are sped up a bit they quietened right down and are smooth little power plants. The Sirius powers at 5 1/2 knots at about 2,800 rpm. It is quiet and easy at this rpm and the controls are conveniently mounted on the steering pedestal. Engine access is via the companionway steps and the port side cockpit locker. It is as good as can be expected on a 28 footer. A Racor fuel-water separator and a water lift muffler are standard. The standard engine is a nine-hp single-cylinder Yanmar. I doubt that it would be as smooth as the two-cylinder model. The Sirius 28 has an impressive list of standard equipment. It certainly pays for the buyer to consider this when comparison shopping. The list includes double batteries, lower lifelines, two sails, stern ladder, wheel, brake and guard, opening ports, bilge pump, painted spar and more. Price these items separately and you get an idea of the real value of the boat. The boat's base price is $52,500. For this you will enjoy a performance cruiser that is simple to sail and as with most boats, will probably take a great deal more punishment than will the crew. Other comments about the Sirius 28 ft sailboat. A quality of design and construction much similar to the Cal, Com-Pac, Sabre, Caliber vessels Canadian boat, has modern rigging including inboard shrouds, inboard sheeting, internal halyards and reefing etc.., over 120 built through mid -eighties. The company no longer in production. Boat sails well in light wind, and is capable in heavy weather. The Interior layout is comfortable for 4-5 people. Lead keel with 40% Displacement. ratio. It is very fast for a cruiser.
Faster, Yup, I'm a corporate pilot... Started on a King Air 200 then a B200 now flying a Citation and a Hawker but I love the 200.... a GREAT airplane!
Thank you, Iflyka200s. The Canadian Yachting article is very helpful. It is but one opinion, however, and based, seemingly, on one experience sailing the Sirius 28. More varied opinions of anyone that has sailed these boats would be great. Comparisons, also. For example, does anyone know how the Sirius 28 compares with the Tartan 30 in particular? These are two boats I'm looking at. The Sirius tends to be sold at a higher price. I know that the Tartans of that era have a reputation for high quality craftsmanship. What of the Sirius? Why the higher price? Simply because they are of a more recent vintage? I can only guess. Thanks, again. Kevin MacTavish
They did not make too many Sirius 28s, so the higher price might a reflection of that.. or perhaps the owner/seller has unrealistic expectations. If you have two particlular boats in mind, spend some time on each, and survey the one that overall appeals to you most. And remember that asking prices are just that, a place to start.
Sirius 28 info I have a Sirius 28 on Lake Superior. I've had it for 8 years and it's an excellent boat. I've raced on dozens of different boats for years before buying my own boat and this one is excellent by comparison. It is very fast for a cruiser. Positive stability when over powered, and as balanced of a boat as i've ever sailed with a 110 headsail. Last weekend we put her nose to the wind, close-hauled and didn't touch the helm for 2 hours. We have auto-pilot mind you, but it wasn't even turned on. The boat just has incredible balance. Looking toward the future, we'd like to get a bigger boat, but I really don't know of any in the 32-34' range that are as easy sailing as our little Sirius 28. VanDestadt & McGruer had planned on making a 31' version when they were shut down in 1989. They were not allowed to operate under bankruptcy in Canada and couldn't get the 31 to market fast enough while the buyer's preferences were changing towards larger boats at that time. They had to basically rebuild their entire factory and all of the molds when the factory had a fire in 1984. Our boat is number 52 (or maybe 54, can't remember off hand exactly) and was molded just before the fire and finished after the fire as far as I can determine in 1984. Any other info you'd like, you can write back and I'll see if I know it. We've had the boat for years and she's gotten us through everything including 12' waves on Lake Superior. She's a great, stout, fast boat with good head room, which you won't find just anywhere.
Paul Howard that wrote the article for Canadian Yachting also did an article on the Sirius 21/22 for them also.Paul and his family know a thing or two about boats and sailing having sailed around the world a couple of times.He build the first boat and the half way through the trip had to make the boat longer,as it was not long enough for the growing family.

Sirius 21 keel

- Sirius 21/22
Hello I'm new to this site as well new to Sirius 21 swing keels. My question to the group is about the keel assembly, is there anything more to the keel assembly than just the pivot bolt and the pivot locking bolt above the pivot bolt. I find my keel is just hanging there very loosely. Should there be some ki g of nylon spacers or metal housing? Thank you.
I've asked a number of people about this as my keel bumps and thuds when chop is on the beam. Apparently, all swing keels have a bit of play. I changed the cable on mine this year (and checked the eye-bolt where it attaches). I would like to check the pivot bolt, but it seems like a serious operation to lower the keel and a difficult one to put it back. Some people with swing keels put in sacrificial plates or similar into the keel trunk area. What was recommended to me was to buy those plastic cutting boards from Ikea and attach them on either side of the trunk. That way the keel is rubbing or bumping on the plastic and not on the fibreglass of the trunk. I would like to know if there are Sirius owners out there who have experience with a worn pivot bolt. Does it wear out?
I'm planning on checking my keels pivot bolt also in a couple days. Right now my boat is off the trailer up on stands for bottom paint so I'll lower the keel and make a wood frame to support it in place then pull the bolt. As this old boat is new to me I have the opportunity now to confirm its safe.
That sounds great. Please keep me posted as to the condition of the bolt so I know if it should be on my list for next season.
Ok so I left the keel up and used a car jack at the front of the keel to pick up the weight, then tapped the pivot bolt about 1/2 way out see image its a 5/8" bolt. Very little rust and little wear. Bit of a pain getting it back in, but if you stick your head in the storage compartment you can see the bolt alignment, I had to jacked the keel up a little and put wedges on both sides of the keel to line up the bolt.
Attachments
Also I used a large clamp on the flat part at the front of the keel to tip the keel you'll need to pull the clamp down if you're on port side lifting the keel parallel as it will drop to starboard when the bolt comes out of the starboad housing.
Good to see the info and pictures. Seeing as how the bolt is in good shape, I think I won't worry about mine too much. At my club and the sail shop they said they've heard of cables failing, but never bolts - unless it had to do with someone running aground at speed.
Hi all, I'm repairing/rebuildin the swing keel locking bolt area on my serius21 as there is just a 1-1/2" dia counter bore with a 3/8" center hole on both sides of the keel trunk. can anyone take a photo of what it should look like? Thanks
JoshuaKairo
Hello, do you still need that photo? I am a new Sirius 21 owner, and I need help with operating the swing keel. How do you lower the keel? I was able to crank up the keel slightly before launching the boat in the water, but now when I turn the winch the other way nothing happens. the winch handle simply rotates freely with no tension on it at all. Is there some kind of clutch/brake or a lever that needs to be moved? Any help would be appreciated.

Aug 18, 2015. #2. Congratulations on your boat purchase and welcome to sailing! The keel is solid cast iron so sandblast away. As far as a motor size 5 HP will be fine just make sure it is a long shaft. Lower motor weight is important in these Sirius 21's because the stern sits down in the water a bit.

Sirius 21. The designs are all recreational keelboats, built predominantly of fibreglass, with wood trim and aluminum spars. They all have transom-hung, kick-up rudders controlled by a tiller and iron swing keels that can be locked down. A fixed, lead, fin keel was an option on the 21 and 22.
