Design and Construction
The Aventura 37 was drawn entirely by Lasta Design Studio, the same office responsible for the Aventura 34 and 44, giving the range a consistent visual language — elegant and dynamic silhouette that the manufacturer describes as unique among catamarans under twelve meters. What makes that silhouette work is the roof arrangement: a double helm seat positioned close to the sunbathing area keeps skipper and guests in the same social orbit rather than marooning the helmsman at a distant wheel.
Construction follows modern practice throughout. Built entirely in infusion in female molds, the hulls use a sandwich matrix of Airex foam, glass, and polyester, with the underwater sections continuing that sandwich construction as far down as the base of the skegs, which then transition to monolithic glass and polyester. Female-mold infusion produces sharper exterior surfaces and more consistent resin ratios than hand layup, and Airex foam coring keeps displacement in check — the boat comes in at a light displacement of 17,400 lbs for a hull just under eleven meters.
Rig, Sail Plan, and Handling
For a boat this size, the upwind sail area is substantial. The standard working canvas — 1,012 square feet between mainsail and genoa — gives a sail-area-to-displacement ratio just above 24, which in catamaran terms suggests responsive performance without needing to carry a gennaker to make ground. The optional asymmetrical spinnaker at 915 square feet and symmetrical at 969 square feet expand the downwind repertoire considerably for those who want to push the boat offshore.
The sail handling station located in immediate proximity to the sail plan is a deliberate layout decision, ensuring that trimming sheets and handling the main does not require the crew to travel the length of the boat. On test in south-of-France conditions, short chop didn't impact the vitality of the Aventura 37 under sail, suggesting the hull lines are sufficiently stiff and buoyant to maintain momentum in the confused seas common along Mediterranean coastlines. Twin 20-horsepower diesels serve as auxiliary power, with an upgrade to 30 horsepower available — adequate for marina maneuvering and motoring in calm conditions, though owners planning extended liveaboard passages in light-air regions often look upward in the range.
Cockpit and Deck Layout
The cockpit is the most immediately impressive feature for guests coming aboard. Generous seating arranged around a large table can accommodate up to eight guests, and the architects have clearly understood that the cockpit is where most people on a catamaran spend most of their time. Direct access to the roof from the cockpit, combined with the sunbathing zone adjacent to the helm, creates what the manufacturer describes as a true open-air living space — a phrase that earns its use here because the geometry actually supports it rather than simply promising it.
Ample storage and an integrated plancha (the outdoor grill-griddle ubiquitous in French-built and French-influenced cruising boats) complete the picture of a boat fostering natural conviviality both underway and at anchor. The capsize screening number sits above 3.0, which is characteristic of beamy, shallow-draft cruising catamarans designed for comfort over pure offshore stability metrics.
Accommodations and Galley
Below, the Aventura 37 offers a three-cabin owner's layout as standard, with a true owner's suite featuring a desk area, a spacious dressing room, and a private bathroom with a separate shower. A four-cabin charter version — offered with two or four bathrooms — allows the boat to serve commercial programs without redesigning the entire interior. The saloon comfortably welcomes five to six guests, which is generous for a boat of this length.
The galley is well-specified for coastal and offshore cruising. Standard equipment includes a 285-liter fridge-freezer, oven, microwave, and dishwasher, along with a navigation station that runs the EmpirBus electrical management system for centralized control of DC loads. Fresh water capacity splits between two 250-liter tanks, and fuel follows the same dual-tank arrangement — two 66-gallon fuel tanks give reasonable range under power when conditions dictate motoring.
Known Considerations
The Aventura 37 is a young model, and the publication record from independent test sources is still relatively thin. The Multihulls World test represents one of the more authoritative on-the-water assessments available, but it was conducted under ESE 10 to 16 knots in moderate sea state — benign conditions that do not reveal how the boat performs in heavier air or sustained offshore passages. Buyers expecting to venture beyond coastal cruising should seek independent reports in stronger conditions before committing.
The 3.94-foot draft is competitive for a catamaran of this beam, but the overall beam of 19 feet, 6 inches will exceed the slip limits of many marinas — a practical constraint that applies to the category broadly but is worth confirming before purchase.
The Verdict
The Aventura 37 is a thoughtfully executed small cruising catamaran that punches above its length in livability. Lasta Design Studio has made smart decisions about where conviviality matters — the cockpit, the helm arrangement, the galley specification — and the infusion construction gives the hull a modern structural foundation. In the thinly populated 11-meter cruising catamaran segment, it has few direct competitors at its specification level, which partly explains the strong order book reported by the manufacturer.
Pros
- Infused Airex sandwich construction throughout, including underwater sections
- High sail-area-to-displacement ratio rewards sailing over motoring
- Cockpit genuinely seats eight, with integrated plancha and roof access
- Owner's suite with private head and dressing room in base three-cabin layout
- Galley specified with dishwasher, oven, microwave, and 285-liter refrigeration as standard
- Four-cabin charter configuration available for charter operators
Cons
- Twin 20-hp engines are modest for a boat of this displacement; the 30-hp upgrade is worth considering
- Published independent sea trial coverage is limited to benign Mediterranean conditions
- 19-foot, 6-inch beam exceeds slip width at many marinas
- As a relatively new model, long-term ownership track record is still accumulating
