Design and Construction
The Aventura 45 is built in fiberglass with polyester resin using the infusion process. It has a 24.6-foot beam, a 4.6-foot draft, and a displacement of 26,455 pounds. The catamaran sits on twin keels and carries a spade rudder.
Good bridgedeck clearance is a defining trait, giving the boat a clean passage through bigger seas without the slamming that plagues low-bridgedeck cruisers. Its 3.3 capsize-screening ratio and 24.24 sail-area-to-displacement figure place it among lively, volume-forward cruising cats rather than heavy-displacement passagemakers.
Rig, Sail Plan, and Machinery
A fractional sloop rig rises to a 72-foot mast. Sail area includes a 74-square-meter mainsail and a 51-square-meter genoa, with an optional 85-square-meter gennaker. This single-masted sloop plan, combined with generous sail area relative to the 12-tonne dry displacement, suggests a boat intended to move in modest air without relying on its engines.
Twin diesel options provide either 45 or 57 horsepower per side. They draw from a 185-gallon fuel tank, while a 211-gallon fresh-water supply supports extended coastal and ocean use.
Accommodations and Tankage
Lasta Design created large volumes and optimized living space across numerous layout versions. The reference specification has four guest cabins and four bathrooms, sleeping eight, plus a single crew berth. The saloon and cabin volumes feel generous rather than merely adequate.
A maximum onboard capacity of 28 people, together with 800-liter fresh-water and 80-liter black-water tanks, shows that the boat was engineered for both private cruising and heavier charter loads. The optional dark beige gelcoat used on hull #1 also shows the builder’s willingness to depart from the usual white-fiberglass convention.
Equipment and Early-Hull Details
Hull #1 carried a hydraulic aft platform, but this was noted on the show boat rather than identified as fleet-standard equipment.
The CE Category A – Ocean rating confirms the design’s offshore intent. Its lower price than competitors positions the Aventura 45 as a value entry in the 44-foot catamaran class, without obvious structural compromise in the build.
The Verdict
The Aventura 45 is a modern, volume-rich cruising catamaran with genuine offshore certification and an infusion-process build. Its narrow, chined bows and tall bridgedeck suit passagemaking, while the numerous layout versions and four-cabin baseline serve both private and charter owners. With no documented end-of-production date, it remains squarely a current-model design.
Pros
- Large, optimized living space with numerous layout versions
- Good bridgedeck clearance for greater comfort on ocean passages
- Infusion-process GRP construction with a CE Category A – Ocean rating
- Competitive price compared with same-size French catamarans
Cons
- Imposing freeboard may not appeal to traditionalist tastes
- Hydraulic aft platform confirmed only on hull #1, not across the fleet
