About the Aloha 85 Sailboat

Designed by the respected team of Ted Brewer and Robert Walstrom, this 28-foot cruising sailboat emerged from Canadian builder Ouyang Boat Works during the mid-1980s. The Aloha 85 represents solid coastal cruising design philosophy, combining moderate dimensions with sensible proportions that appeal to sailors seeking comfortable weekending and extended coastal exploration. Built with fiberglass construction and featuring a fin keel with transom-hung rudder configuration, the boat offers predictable handling characteristics and reasonable performance under sail. The masthead sloop rig provides versatile sail combinations, while the generous beam of 9.42 feet creates substantial interior volume for a boat of this length. With a displacement of 6,750 pounds and ballast ratio supporting the 395 square feet of sail area, the design strikes a balance between stability and sailing ability. The boat's comfort ratio of 20.58 suggests good motion characteristics for coastal cruising, while the capsize screening value of 2 indicates reasonable stability for protected waters and moderate offshore conditions. Ted Brewer's influence is evident in the thoughtful proportions that prioritize seaworthiness and livability over pure racing performance. Though production was relatively brief, lasting from 1983 to 1988, the Aloha 85 earned respect among cruising sailors for its practical approach to small boat voyaging.
