About the ALLIED 39

Derived from the wooden OWENS CUTTER, 6 boats of this design were first built in fiberglass and sold as the BORSAW 40. The mold was then sold to Allied Boat Company. With a few changes it became the ALLIED 39. The traditional transom was changed to a reverse transom, the underbody was redesigned by Robert Harris to a more modern fin keel, and slightly more beam. Available as a Sloop or Yawl.

Sailpages Buyer's Take

The Allied 39 is a robust, heavy-displacement cruising sloop designed by George Owens and Robert Harris, built by Allied Boat Co. (USA) between 1970 and 1973. With a displacement of 17000.0 lb and a D/L ratio of 316.71, this vessel prioritizes stability and seakeeping over speed, reflecting the classic bluewater design ethos of the early 1970s.

Best for:
This boat is ideally suited for serious coastal and offshore cruisers who value comfort and safety in heavy weather, as indicated by its high Comfort ratio of 35.68 and substantial ballast of 6699.7 lb. It appeals to owners willing to perform significant maintenance and upgrades, given the high frequency of reported structural repairs and the prevalence of modern engine and electronics installations.
Bluewater capability:
The Allied 39 demonstrates strong offshore suitability with a low Capsize ratio of 1.64 and a high D/L ratio of 316.71, indicating excellent stability and resistance to capsizing in heavy seas. Its proven history in owner reports, combined with the prevalence of bluewater-specific upgrades like watermakers and bow thrusters, supports its capability for extended passages.
Comparables:
Comparable boats include the Cal 40 and the O'Day 39, which share similar production eras (early 1970s) and heavy-displacement, fin-keel characteristics. These vessels are comparable because they all feature masthead sloop rigs and were designed for comfortable, stable cruising rather than racing performance.
