Design and Construction
The Aventura 45 is built in fiberglass with polyester resin using the infusion process. At 24.6 feet of beam and a 4.6-foot draft, the 26,455-pound 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 anchor without the slamming that plagues low-bridgedeck cruisers. The 3.3 capsize-screening ratio and 24.24 sail-area-to-displacement figure place her among lively, volume-forward cruising cats rather than heavy-displacement passagemakers.
Rig and Sail Plan
A fractional sloop rig rises to a 72-foot mast, carrying a 74-square-meter mainsail and a 51-square-meter genoa, with an 85-square-meter gennaker available as an option. The single-masted sloop plan and the generous sail area relative to the 12-tonne dry displacement suggest a boat built to move in modest air without recourse to engines. Twin diesel options of 45 or 57 horsepower per side feed from a 185-gallon tank, supporting a 211-gallon fresh-water supply for extended coastal and ocean use.
Accommodations
Lasta Design created large volumes and an optimized living space across numerous layout versions anchor, and the reference spec confirms a four-guest-cabin, four-bathroom arrangement sleeping eight with a single crew berth. The 28-person maximum onboard capacity and the 800-liter fresh-water and 80-liter black-water tanks show a boat engineered for both private cruising and heavier charter loads. The saloon and cabin volumes read as generous rather than merely adequate, and the optional dark beige gelcoat on hull #1 signals a builder willing to depart from white fiberglass convention.
Equipment and Early Hull Details
Hull #1 carried a hydraulic aft platform, an item noted on the show boat rather than cited as fleet standard. The CE Category A – Ocean rating confirms the design's offshore intent, and the lower price than competitors positions the 45 as a value entry into 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. Her narrow chined bows and tall bridgedeck suit passagemaking, while the many layout versions and four-cabin baseline serve both private and charter owners. The lack of documented end-of-production dating leaves her squarely a current-model design.
Pros
- Large optimized living space with numerous layout versions
- Good bridgedeck clearance for ocean passage comfort
- Infusion-process GRP build with CE Category A – Ocean rating
- Competitive price against same-size French catamarans
Cons
- Imposing freeboard may not suit traditionalist tastes
- Hydraulic aft platform confirmed only on hull #1, not fleet-wide
