The Endeavour 37 emerged from a characteristically Florida story of borrowed molds, borrowed talent, and borrowed ambitions. Founders Rob Valdez and John Brooks brought experience from Columbia, Gulfstar, Charley Morgan, and Irwin before establishing Endeavour in 1974. The 37 itself grew from a creative act of necessity: an old Ray Creekmore design was cut in half and three feet added to the midsection, producing a 37foot hull that designer Dennis Robbins then shaped into what became Endeavour's flagship cruiser. Introduced in 1977 and built through 1983, the boat found its market quickly — 476 hulls were sold across sloop, cutter, and ketch variants, a substantial run for an American production cruiser of that era. The founders had always kept one eye on Gulfstar's customer base, and it showed: the Endeavour 37 was conceived as a capable, comfortable coastal cruiser for sailors who valued liveability over speed.

Hull and Construction

The Endeavour 37's structural philosophy is straightforward. The hull is a single-skin, solid fiberglass laminate of polyester resin with woven roving and multi-directional chopped strand fiber — no exotic materials, no core, no frills. The keel is molded integrally with the hull, with lead ballast contained inside, eliminating keel bolts entirely. That arrangement has practical advantages for a cruising boat: there are no bolts to corrode, and the boat can take the bottom without the threat of keel separation. The deck is similarly solid laminate, with plywood coring in the cabin top and cockpit sole areas for stiffness. Hull and deck join at an outboard flange sealed with adhesive compound and covered by a teak cap rail — an assembly detail the factory considered one of the most critical steps in production.

The construction is honest and heavy, and owners consistently report it feels that way. One owner who described woodworking as a hobby noted the trim joints were excellent, and the interior is generally well finished for its era, with varnished teak, teak parquet cabin sole, louvered hanging locker doors, and Formica counter tops. What the build lacks in sophistication it compensates with durability.

Rig and Sailing Performance

The Endeavour 37 was offered as a sloop, ketch, or cutter, and the rig options evolved during production in response to owner feedback. The sloop is somewhat underpowered, and the ketch appears to give the boat much-needed sail area. A bowsprit option was added at one point to increase the foretriangle area, and a tall mast was also available — both changes reportedly introduced to address owner requests for better sailing performance. Rigging is conventional masthead configuration with 1x19 stainless standing wire, aluminum 6061-T6 spars, and Lewmar winches throughout: number 8 single-speed on the mast for halyards, number 40 self-tailing in the cockpit for sheets.

In practice, the 37 is not a fast boat, and this is not a criticism so much as a design acknowledgment. PHRF ratings run from 177 to 198 depending on rig and region, placing it well behind competitive 37-footers. Many owners report heavy weather helm in higher winds, which the bowsprit and larger foretriangle were intended to mitigate. The boat points no better than its hull form allows, with some owners reporting tacking angles around 115 degrees and noticeable leeway — predictable behavior from a shallow, long keel with a straight run. The D/L ratio of 331 and a SA/D of only 12.46 confirm what sailors find on the water: a heavy, stable, undemanding cruiser that moves well in a breeze but will not chase anyone upwind. Multiple charter operators including Bahamas Yachting Services have deployed the 37 for offshore passages between the Bahamas and Virgin Islands, which says something meaningful about its seakeeping character if not its windward angle.

Engine and Mechanical Systems

The standard Perkins 4-108 is a real workhorse and something of a benchmark against which other marine diesels are measured, freshwater-cooled and rated at 50 hp with a 2.57:1 reduction gear. It is adequately sized for the boat's 20,000-pound displacement, and mechanics consistently regarded it among the best marine diesel engines of its era. Companionway steps are removable to access the engine compartment, and sound insulation is fitted inside the engine box. Fuel capacity is around 55 to 65 gallons in a baffled tank, providing reasonable range under power.

The standard propeller was a solid bronze two-blade, though many owners switched to a three-blade for better control in reverse — a common trade-off that costs some performance under sail. A feathering three-blade would be the more elegant solution, preserving sailing performance while solving the reverse-control problem. The propeller shaft is 1-1/4-inch stainless, supported by a cutlass bearing in a cast bronze strut. Electrical wiring runs mostly above the waterline and is accessible by removing panels from under the side decks, which is more thoughtful than many contemporaries managed.

Accommodations

The Endeavour 37 offered three interior layouts, and the choice between them reflects genuinely different cruising philosophies. Plan A — the original and more unusual of the two main options — replaced the forward V-berths with an enormous U-shaped dinette whose table converts to a large double berth. This arrangement creates an unusually open, airy main cabin with good fore-to-aft air circulation and a generously proportioned social space. Plan B is the conventional alternative: V-berths forward, settees in the saloon with an offset dropleaf table, pilot berth above the starboard settee, and a private aft quarter cabin to port. A high percentage of owners are liveaboards who consider the boat ideal for their purposes, and both layouts explain why — there is genuine space for two couples to move about without friction. The aft cabin in Plan B, however, is cramped and poorly ventilated, and the main bulkhead interrupts airflow through the saloon, a genuine liability in tropical use.

Standard equipment included 6-foot-3-inch headroom, six berths, 100 gallons of fresh water with hot and cold pressure, a full head with shower, and either a three-burner alcohol or LPG stove. The teak parquet cabin sole is a signature detail — owners either appreciate its distinctiveness or simply tolerate it, but it is unmistakable. Ten opening portlights and three deck hatches provide ventilation, though in practice owners still find the boat warm in calm tropical conditions.

Known Issues and Maintenance Considerations

The Endeavour 37 carries a few recurring problems that any prospective buyer should examine carefully. Gelcoat crazing was cited by numerous owners and is consistent with reports on the Endeavour 32 — a result of the era's resin chemistry and production methods rather than any structural defect, but cosmetically significant and expensive to correct properly since gelcoat color matching on aged hulls is rarely satisfactory. More seriously, osmotic blistering affected a meaningful number of hulls surveyed; any boat inspected today should have documentation of blister repair or a fresh barrier coat application.

Original gate valves on through-hulls have typically been replaced with proper seacocks by conscientious owners, but any boat that has not had this work done needs it immediately. The Isomat spar on some boats was noted as problematic. Some early refrigerators were side-loading units that owners converted to top-loading iceboxes. V-berths can be short for taller sailors. Water and holding tank placement caused minor listing on some boats — a problem addressable with flexible tank repositioning. Plastic Vetus hatches on some hulls have crazed and dripped over time.

The internally ballasted keel, while eliminating keel-bolt concerns, creates its own consideration: in any significant grounding, the fiberglass skin over the ballast cavity must be inspected for puncture. If water enters, the laminate requires thorough drying — a slow process — before repairs can be made properly.

Deck and Cockpit

On deck the Endeavour 37 is uncluttered and practical. Side decks are wide, the foredeck is adequate for sail handling, and the toerail rises forward to create a low bulwark that provides meaningful security when handling ground tackle or changing headsails. The cockpit is large — some observers consider it borders on too large for offshore passages, given the volume of water a pooping wave could deposit — though the bridgedeck and weather boards provide a measure of protection from water reaching below. The wraparound cockpit coaming is the boat's most distinctive visual feature: high, sweeping, and polarizing. Owners either find it a welcome backrest and safety feature or an aesthetic overstatement atop the already high freeboard. Its one practical advantage is that it makes fitting a full dodger straightforward.

The Verdict

The Endeavour 37 is an honest cruising boat built for the waters it was designed to sail — the shoal-draft reaches of Florida, the Bahamas, and the island chains where draft matters more than pointing angle. Its construction is heavy and sound, its accommodations genuinely liveable, and its engine installation one of the better choices of the era. The boat does not pretend to be a performance sailor, and buyers who accept that find much to appreciate.
