The Endeavourcat 36 represents a pivotal moment in American multihull history, marking Endeavour Catamaran Corp.’s transition from traditional monohulls to specialized cruising catamarans. Launched in the early 1990s and built in Clearwater, Florida, the 36 was designed with a specific niche in mind: providing the stability and volume of a multihull while maintaining a 15-foot beam, allowing it to fit into standard monohull slips. This "slip-friendly" philosophy, combined with a shallow 2’ 9” draft, made the vessel an immediate favorite for coastal cruisers and Great Loop enthusiasts who needed to balance living space with marina accessibility. While early models were primarily sailing catamarans (often referred to as the Sport 36), the hull’s success eventually led to the development of the TrawlerCat 36, which removed the mast in favor of larger twin diesels and a more power-centric cruising profile.

Sailing Performance & Handling
The sailing version of the Endeavourcat 36 utilizes a distinctive tri-stay rig that eliminates the need for a backstay, simplifying the deck layout and allowing for a large, roached mainsail. According to manufacturer specifications and owner tests featured on Passagemaker, the boat is designed for ease of handling, with all lines led aft to the helm, facilitating single-handed operation. Performance is respectable for a cruising multihull; the knifelike hulls have a fine entry and are easily driven, allowing the boat to cruise at 60% of the true wind speed up to 8 knots. In fresher breezes, the 36 has been reported to exceed 15 knots, though its primary focus remains stable, level sailing rather than raw racing speed.
The boat’s tracking is aided by its deep-V hull shape, which provides sufficient lateral resistance to perform well to windward without the complexity of daggers or centerboards. At an apparent wind angle of 35 to 40 degrees, the vessel maintains a steady 7 to 8 knots. Handling is further enhanced by the "steerable" propulsion system found in outboard-equipped models, where the engine turns in synchronization with the rudders, providing exceptional low-speed maneuverability in tight marinas.
Interior Comfort & Variations
The interior of the Endeavourcat 36 is noted for its "galley-down" configuration and an expansive bridge deck salon that provides 360-degree visibility. The standard layout features three staterooms: one double berth aft in each hull and a third "athwartships" double berth located forward of the salon. This three-cabin arrangement is highly efficient for a 36-foot platform, though it does result in a slightly more compact salon compared to wider-beam catamarans.
The port hull is traditionally dedicated to a longitudinal galley, which includes double stainless steel sinks and a two-burner stove, while the starboard hull houses a large head with a dedicated stall shower—a luxury rarely seen in vessels of this size. With a full 6 feet of standing headroom throughout and excellent ventilation provided by large Bowmar hatches, the boat avoids the "tunnel" feeling common in smaller catamarans. The TrawlerCat sibling variant maintains this layout but replaces the cockpit's sailing hardware with a fully enclosed pilothouse and a hardtop, turning the aft deck into a sheltered living space.
Popular Mentions & Media
The Endeavourcat 36 gained significant visibility through the editorial piece "Skinning a Cat," published by Passagemaker Magazine, which chronicled an owner's transition from a monohull to the TrawlerCat 36 variant. The model is also a frequent subject of "Great Loop" travelogues on YouTube, where its 15-foot beam and low air draft are cited as critical advantages for navigating the inland waterways of North America.
Known Issues & Buyer’s Checklist
- Core Integrity: The hulls and decks are vacuum-bagged with a honeycomb core. Buyers should perform a thorough percussion test or use a moisture meter around the stanchion bases and deck fittings, as any water intrusion can lead to delamination that is difficult to repair in honeycomb structures.
- Engine Ventilation: On earlier models, particularly those with the twin 18hp Yanmar diesel configurations, engine room ventilation has been a noted point of concern. Inspectors should check for signs of heat-related wear on hoses and wiring in the aft hull compartments.
- Outboard Linkage: For sailing models equipped with the single 25hp Honda outboard, the mechanical linkage that allows the engine to turn with the rudders can become stiff or corroded over time. Verify that the steering remains fluid through the full range of motion.
- Acrylic Windows: The large wraparound salon windows are prone to crazing and seal failure due to UV exposure and the slight torsional flexing of the catamaran platform. Check for evidence of leaking or previous "re-bedding" attempts with silicone.
Community & Resources
The most active hub for technical data and owner support is the Endeavour Owners Forum, which covers both the legacy monohulls and the catamaran line. Additionally, the manufacturer, now operating as Endeavour Corporation in Clearwater, Florida, continues to offer limited support and documentation for older models through their corporate archives.
The Verdict
The Endeavourcat 36 is an ideal "bridge" vessel for sailors moving from monohulls to multihulls who are unwilling to sacrifice marina access.
Pros:
- Marina Friendly: The 15-foot beam fits into most standard slips.
- Low Draft: 2’ 9” draft is perfect for the Bahamas or the ICW.
- Ease of Use: Simple tri-stay rig and single-handed control layout.
- Living Space: 3 cabins and a separate stall shower on a 36-foot frame.
Cons:
- Bridge Deck Clearance: Like many cruising cats of this era, it can experience "pounding" in heavy head seas.
- Core Material: Honeycomb cores require vigilant maintenance to prevent water damage.
- Narrower Salon: The "slip-friendly" beam limits the width of the main living area compared to a 20-foot wide cat.
