Sailpages Buyer's Take

The Endeavour 51 is a substantial cruising yacht designed by Johan Valentijen and built by Endeavour Yacht Corp. (USA) in 1985. With a displacement of 37000.0 lb and a comfort ratio of 34.6, this vessel represents a heavy, stable platform from a short production run.

Best for:
This boat is best suited for experienced coastal cruisers and those seeking a comfortable, stable passage-making yacht, given its high displacement and beam of 15.0 ft.
Bluewater capability:
With a capsize ratio of 1.8 and a D/L ratio of 219.01, the Endeavour 51 demonstrates strong offshore stability and seakeeping characteristics suitable for bluewater cruising.
Comparables:
Comparable vessels include other heavy-displacement American cruising yachts from the mid-1980s, such as the Tartan 4200 or O'Day 38, which share similar design philosophies prioritizing stability and interior volume over pure speed.
