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.

Aloha Owners
Association
The aim of the Association is to enable owners of these Aloha models to participate as a group in all aspects of Aloha sailing. We have owner/boat details of just over 375 of the approximately 500 boats built in these series. Except for the Aloha Forum discussion pages, all parts of this website are accessible without registration. If you own an Aloha and would like your details including in the Owners Listings, please spend a couple of minutes signing up with the Association completely free by filling and submitting the registration form with your boat details and contact information. We promise that your personal data will never be used other than for Association purposes.
Please also take time to sign up to the Alohaowners Forum (also free!), by seeing information about how the Forum works. Because we are a no-subscription association, we don’t have a regular newsletter and this forum is the primary and very active means of communication among members and a valuable source of Aloha chat and information. Both owners and all others interested in Aloha related topics are welcome to join the Forum.
Follow the menu options on the left for areas of the site that interest you and click away. The site is regularly updated as more information becomes available, so check back from time to time in the future and see the What’s New page for details. As well as the models listed above, the Aloha range included the Aloha 34 (10.4) whose owners have their own group with a website at Aloha 34 Network. At least one “prototype” Aloha-Perry 41 was produced, with the intention to add a 47 as well, as shown in this copy of an Aloha Yachts advertisement. Before (and for a while after) introducing the Aloha range, Ouyang also manufactured a number of the Matilda 16, 20 & 23. We are not aware of any owners association for these boats, but a more information and links can be found on this Matilda Sailboats web page. If you have information, articles or pictures that you think will be of interest email these to us.

Designed to determine if a boat has blue water capability. The CSF compares beam with displacement since excess beam contributes to capsize and heavy displacement reduces capsize vulnerability. The boat is better suited for ocean passages (vs coastal cruising) if the result of the calculation is 2.0 or less.

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.
The Aloha 28 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a vertical transom, a transom-hung rudder mounted on a skeg and a fixed swept fin keel. It displaces 6,750 lb (3,062 kg) and carries 3,000 lb (1,361 kg) of ballast. [1]
The Aloha 28 is a sailboat designed by the Canadian maritime architect Edward S. Brewer together with Robert Walstrom in the early seventies. The Aloha 28 is built by the Canadian yard Aloha Yachts.

The ALOHA 8.5 is an updated version of the ALOHA 28, introduced in 1983. The main difference between the 2 boats is the installation of 5 opening port lights down each side of the vessel, and the addition of more brightwork, including a trim piece running horizontally above the port lights.
