Aventura 37 Sailboats for Sale

Layouts on the Used Market

The standard boat is a three-cabin arrangement with a true owner’s suite — a desk nook, a generous wardrobe room, and a private bath with a separated shower stall — while a four-cabin charter version was offered with two or four bathrooms. Ex-charter examples are common, so buyers will see both the owner-spec layout and higher-density charter fits. The saloon welcomes five to six guests and the cockpit seats up to eight around a large table; the roof carries a dedicated sunbathing area with direct access from the cockpit and a double helm seat close by.

Equipment and Common Upgrades

Most boats on the market carry a chartplotter and autopilot as standard navigation, with solar, a freezer, dinghy davits, a short-handed sail-handling setup, an inverter, and a life raft often seen as part of the cruising inventory. Less commonly, buyers will find a bimini, AIS, air conditioning, heating, a furling main, electric winches, or hot water as owner upgrades. For a catamaran of this size the meaningful clusters are power and energy — solar and inverter supporting the EmpirBus-managed 12V systems and freezer — and sail handling, where a short-handed setup and davits speak to self-sufficient anchoring and trimming without crew.

What to Inspect

The build method is the main inspection lens: the 37 is infused with an Airex foam, glass, and polyester sandwich throughout, and the underwater hulls remain sandwich down to the skegs before becoming monolithic glass and polyester at the base sandwich hulls with monolithic glass at the skeg bases. On any ex-charter four-cabin example, check the additional bathroom modules and cabin joinery for charter-wear and the plumbing seals around the 285-liter fridge-freezer galley, oven, microwave, and dishwasher. The integrated plancha in the cockpit and the direct roof-access steps are points where gelcoat and hardware should be examined for stress.

Availability and Buyer's Takeaway

Aventura 37s typically appear in Spain, Croatia, Tunisia, Italy, Australia, and the Netherlands. For a buyer, the checklist is straightforward: confirm whether the layout is the owner three-cabin or charter four-cabin with two or four heads; verify the navigation and energy cluster (chartplotter, autopilot, solar, inverter, freezer) is intact; inspect the infusion sandwich hull and skeg-base monolithic sections for impact; and treat air conditioning, heating, furling main, and electric winches as negotiable upgrades rather than expected equipment.
