Aventura describes the 37 as unique among catamarans under 12 meters because her deck and interior place an emphasis on social spaces close to the helm.
Design and Construction
The Aventura 37 measures just under 12 meters overall—10.90 m loa—with a beam of 5.94 m. She’s a light-displacement, twin-keel catamaran weighing 7.9 t, with a draft of 1.20 m. That shallow twin-keel configuration reflects a shoal-water cruising brief rather than an emphasis on speed to windward. Her capsize ratio is 3.01, in keeping with a moderate cruising multihull.
Aventura built the 37 entirely by vacuum infusion in female molds. Construction uses an Airex foam, glass and polyester sandwich matrix throughout, including the underwater hulls. The sandwich continues to the base of the skegs, before transitioning to monolithic glass and polyester at the lowest vulnerable sections.
This infusion process is central to the boat’s structure. It produces a consistent, void-free laminate intended to keep displacement low for a 38-foot catamaran while retaining the panel stiffness required of a performance cruiser.
Rig and Sail Handling
The Aventura 37 carries a fractional sloop rig with 94 m² of upwind sail area: a 58 m² mainsail and a 36 m² genoa. For downwind sailing, buyers can add a 60 m² gennaker, an 85 m² asymmetrical spinnaker or a 90 m² symmetrical spinnaker.
The sail-handling station sits close to the rig. A double helm seat is integrated into the roof beside the sunbathing area, with direct access from the cockpit to this dedicated relaxation space. The arrangement keeps the helm connected to both sail trim and the crew instead of isolating it at a wing station.
Cockpit and Interior
Samer Lasta also carefully designed the interior layout and ergonomics. The standard three-cabin version includes a true owner’s suite with a desk area, a roomy walk-in dressing space and a private head with its own standalone shower.
A four-cabin charter version is also available, with either two or four bathrooms. The saloon comfortably accommodates five to six guests, while the cockpit provides generous seating around a large table for up to eight.
The galley has an unusually complete domestic setup for a boat of this size, including a 285-liter fridge-freezer, oven, microwave and dishwasher. The navigation station incorporates the EmpirBus electrical management system.
Equipment, Tankage and Propulsion
Beyond the galley and navigation-station equipment, the 37 has a 12V refrigerator-freezer of 200–75 l and an integrated plancha in the cockpit.
Fresh-water capacity is 2 x 250 l, matched by fuel capacity of 2 x 250 l. The boat also carries an 80 l holding tank. This parity between water and fuel capacity is a deliberate cruising gesture, intended to support long-range autonomy without giving up the generator-free simplicity of the standard layout.
The standard powertrain is 2 x 20 hp, with 2 x 30 hp available as an option. The Aventura 37 carries CE certification A8/B12/C16/D20.
The Verdict
The Aventura 37 is a thoughtfully modern small catamaran. She combines light, infused construction with a layout that allows the helm, sail-handling station and social areas to work together instead of competing for deck space.
Her interior is genuinely equipped for liveaboard use, and the owner’s suite rises above the usual compromises of a three-cabin charter layout. She’s very much a 2021-era design, with a clear lineage from Lasta Design’s earlier work for Aventura. Several dozen boats were on order at launch.
Pros
- Full infused sandwich construction, with monolithic glass at the skeg bases, keeps weight low and the structure sound
- Roof-mounted helm seat sits near the sunbathing area and has direct cockpit access
- True owner’s suite with a desk, dressing room and private head with a separate shower
- Galley includes a 285-liter fridge-freezer, oven, microwave and dishwasher
- Balanced 250 l water and fuel capacity, plus an 80 l holding tank
Cons
- Standard 2 x 20 hp powertrain is modest; 30 hp engines are optional only
- Her under-12-meter niche puts her up against better-known production catamarans
