HALCYON 27

About the HALCYON 27

Based on the earlier DIAMOND 27 built by Thames Marine Ltd.(UK).

Designed by Alan Buchanan and built by Offshore Yachts Ltd. (UK) from 1968–1975, the Halcyon 27 is a classic full-keel sloop with a displacement of 6720.0 lb and a comfort ratio of 30.89. While the exact hulls built count is unknown, the fleet is characterized by its heavy displacement and traditional layout, with a significant portion of owners having upgraded to modern engines like Yanmar and electronics such as Autohelm.

Best for:

This boat suits coastal cruisers and those seeking a traditional, stable platform for shorthanded sailing, given its high comfort ratio and full keel design. It is also popular among owners who enjoy extensive DIY maintenance and upgrading, as evidenced by the high frequency of reported solar panel, watermaker, and sail upgrades.

Bluewater capability:

With a capsize ratio of 1.63 and a displacement of 6720.0 lb, the Halcyon 27 is well-suited for offshore passages, offering excellent stability and a proven full/long keel form that resists capsizing in heavy weather.

Comparables:

Comparable boats include the Hallberg-Rassy 35 and the Tartan 34, which share similar full-keel, heavy-displacement characteristics and traditional layouts from the same era. These vessels are comparable because they prioritize seakeeping and comfort over speed, appealing to buyers looking for robust, classic cruising yachts.
