Aloha 28 (8.5) Specs

Disclaimer:

Please Note, during the lengthy production runs of the A27 (8.2) and A28 (8.5), Ouyang Boatworks used a number of different mast and sail suppliers and specifications with differing mast and boom lengths. We are not aware of similar variations in the A30 and A32 models, but it is always possible. With this in mind, please do not rely on the measurements provided if you have to pass under an overhead obstruction (eg bridge or powerlines) where clearance will be limited, when ordering sails or establishing a racing handicap. If you require accurate numbers for any of these purposes we strongly recommend you measure your actual boat and we accept no responsibility for the consequences of any inaccuracies in the quoted figures, or in variations applying to your boat.

Aloha 32 368

Ti Ouyang started Ouyang Boat Works in Whitby, Ontario, in the late 1960s. In the 1970s, he contracted several naval architects to contribute designs for the company’s new line of Aloha cruising boats. Ouyang selected a submission from Mark Ellis for the Aloha 32, which was introduced in 1979 and continued in production until 1988, by which time the company had built approximately 700 boats.

To give the Aloha 32 its classic “yachty” look, Ellis drew a strong, springy sheer, a delicate spoon bow, and a raked transom with a slight overhang. Aesthetically, the short bowsprit serves to extend the sheer line; technically, it lengthens the foretriangle to compensate for the somewhat forward placement of the fin keel. The wide cove stripe accentuates the sheer, and the teak trim along the cabin top visually reduces the cabin’s height.

The hull is solid fiberglass, and the deck is cored with end-grain balsa. The deck fits hatbox fashion to the hull and also lands on an inward flange on the hull, where it’s chemically bonded and bolted on 4-inch centers.

The Aloha 32 was available in two interior configurations. One setup offers a traditional V-berth cabin and a saloon with opposing settees. In the other arrangement, a workshop, sail bins, and stowage replace the V-berth. This “all-business” space is separated from the main saloon by a pair of hanging lockers. In the saloon, opposing settee berths flank a centerline drop-leaf table. Both configurations include a generous head compartment with a shower and a wet locker and an L-shaped galley with a sink, a propane stove with an oven, and a well-insulated icebox.

The Aloha 32’s keel-stepped mast supports a high-aspect-ratio masthead sloop rig. All sail controls lead aft so the sails can be handled from the safety of the cockpit. In lieu of a traveler, two main sheets are fitted in an inverted-V arrangement, with one sheet cleated on either side of the companionway hatch.

The Aloha 32 is light, so it accelerates well, and its tall rig helps it move along in light air. In heavy air, the mainsail should be reefed early. With properly shortened sails, the boat sails on its feet, at or near its hull speed of 6.7 knots.

For auxiliary power, the Aloha 32 originally relied on a two-cylinder, 16-horsepower Atomic diesel. In 1985, there was a switch to the more powerful three-cylinder, 21-horsepower Westerbeke diesel, which is able to push the boat along close to its hull speed.

Anyone considering an Aloha 32 should check for loose aft keel bolts, reportedly a result of bilgewater degrading some of the steel structural components. The wooden chainplate knees are also subject to rot.

The Aloha 32 is a comfortable, traditionally styled cruising sailboat. The boat is a little light for serious bluewater work, but it’s more than adequate for coastal cruising and that escape you’re planning to the Bahamas. Condition is everything, but expect to pay between $30,000 and $45,000.

Aloha 28 is a 27 ′ 11 ″ / 8.5 m monohull sailboat designed by Edward S. Brewer and built by Ouyang Boat Works between 1972 and 1988.

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)

Similar to the later ALOHA 8.5. Dimensions for tall rig: I:37.00’ / 11.28m J:12.00’ / 3.66m P:32.00’ / 9.75m E:10.50’ / 3.20m Apparently there were other rigs besides the ones described here.

International Competition 2018, Moscow, Russia.

22nd July 2018 Congress Center of the WTC, Moscow, Russia.

“It is a special day because we are in Russia and you’re here; we’re all together here with our children”.

On 22nd July 2018, 17 countries (Bangladesh, China, Croatia, Ecuador, Germany, India, Ireland, Malaysia, Mexico, Nepal, Panama, Philippines, Portugal, Russia, Spain, Sweden, and Uzbekistan) participated in the competition and celebrated with us the 25th anniversary of ALOHA at Moscow’s World Trade Centre (WTC).

In the morning of the event day, nearly 1,500 parents and 600 children gathered at the Congress Center of the WTC, greeted by ALOHA International and ALOHA Russia team members, and entered the hall decorated with hand-painted wallpaper featuring Moscow scenic skyline. Before the competition began, overseas delegates entered the hall as flag bearers, carrying their respective national flag, whereas children, the national representatives waved their national flags. Participants also observed the Ceremony for Signing the Memorandum of Understanding (MOU) between ALOHA International and Mr. Deepak Joshi from Nepal.

Parents and children returned to the Congress Center at 2pm. The prize-giving ceremony began with the ‘Colours of the World’ concert, where children from various countries performed and demonstrated their national culture to the audiences. It was echoed with rounds of applauses. The concert was preceded by a keynote speech by Mr. Loh Mun Sung, the Founder President of ALOHA Mental Arithmetic, and Dr. Janna Khegai, the Director of ALOHA Russia. Winners received the symbolic 25th Anniversary ALOHA-going-global trophies from VIP guests when names are announced. The event came to an end with the vote of thanks to all parties contributed to make the event a huge success.

Children spent the rest of their stay visiting Moscow and St. Petersburg with their families and other ALOHA children from the rest of the world.

We will continue to, quoting Mr. Loh’s keynote speech, “do the best for our children” in the coming years. We look forward to seeing you again next year!
