Design and Construction
Aventura built the 37 entirely by vacuum infusion in female molds with an Airex foam, glass, and polyester sandwich matrix throughout — including the underwater hulls, which remain in sandwich construction down to the base of the skegs before transitioning to monolithic glass and polyester at the lowest vulnerable sections. That infusion approach is the structural story of the boat: a consistent, void-free laminate that keeps her displacement low for a 38-foot cat while preserving the panel stiffness a performance cruiser needs. The 1.20 m draft of the twin keels reflects a shoal-water cruising brief rather than speed-to-windward optimization, and the 3.01 capsize ratio sits where a moderate-cruising multihull ought to.
Rig and Sail Handling
The standard sail plan is a 94 m² upwind configuration, but the optional downwind inventory is where the 37 shows her cruising intent: a 60 m² gennaker, an 85 m² asymmetrical spinnaker, or a 90 m² symmetrical spinnaker can all be carried. The sail handling station sits in immediate proximity to the sail plan, and the roof integrates a double helm seat positioned close to the sunbathing area, with direct access from the cockpit up to that dedicated relaxation space. The result is a helm that stays connected to both crew and trim, rather than isolated at a wing station.
Accommodations
Inside, the layout and ergonomics were carefully designed by Samer Lasta, and the boat is offered as standard in a three-cabin configuration with a true owner’s suite containing a desk area, a roomy walk-in dressing space, and a private head with its own standalone shower. A four-cabin charter version is available with two or four bathrooms, and the saloon comfortably welcomes five to six guests. The cockpit itself holds generous seating around a large table for up to eight, and the galley is fully equipped with a 285-liter fridge-freezer, oven, microwave, and dishwasher — an unusually complete domestic setup for a boat this size. The navigation station incorporates the EmpirBus electrical management system.
Equipment and Systems
Beyond the galley and nav-station details, the 37 carries a 12V refrigerator-freezer of 200–75 l, an integrated plancha in the cockpit, and a fresh-water capacity of 2 x 250 l against a fuel capacity of 2 x 250 l with an 80 l holding tank. The standard powertrain is 2 x 20 hp with an optional 2 x 30 hp, and the boat carries CE certification A8/B12/C16/D20. Tankage parity between water and fuel is a deliberate cruising gesture, giving long-range autonomy without sacrificing the generator-free simplicity of the standard layout.
The Verdict
The Aventura 37 is a thoughtfully modern small catamaran: infusion-built, light on her lines, and arranged so that the helm, sail handling, and social spaces flow together rather than competing for deck real estate. Her interior is genuinely equipped for liveaboard use, and the owner’s suite is a cut above the typical three-cabin charter compromise. She is a 2021-era design with a clear lineage from Lasta Design’s earlier Aventura work, and several dozen were on order at launch.
Pros
- Full infusion sandwich construction with monolithic glass at skeg bases keeps weight low and structure sound
- Helm seat integrated into roof near sunbathing area with direct cockpit access
- True owner’s suite with desk, dressing room, and separate-shower bath
- Galley with 285-liter fridge-freezer, oven, microwave, dishwasher
- Balanced 250 l water and fuel capacity with 80 l holding tank
Cons
- Standard 2 x 20 hp powertrain is modest; 30 hp optional only
- Under-12-meter niche places her against better-known production cats
