The STGi shipyard started at the turn of the millennium with sailing catamarans for Aventura Catamarans. Until 2017, it also built for Kerkena Sailing and Sterne Fish Motor Boats. The Tunisian shipyard, under the management of Frenchman Romain Roger, now focuses exclusively on the Aventura brand. Production takes place in Menzel Bourguiba, around 75 kilometres north-east of Tunis. Carpentry and upholstery work is carried out in France, while assembly takes place in Tunisia. The first motorised catamaran, the Aventura 10, arrived in 2016. The Aventura 14 followed in 2021, and we were able to test the power cat after the International Multihull Show. Sales in Germany are handled by cat sale GmbH & Co. KG owned by Klaus Tietze in Bremen. At least €866,570 must be saved up for the basic equipment.
The Aventura 14 in detail:
We go on board via the 1.80 metre long bathing platform. A staircase on the starboard side leads to the cockpit with a large L-shaped upholstered bench and table and the entrance to the skipper's cabin in the port hull. This is followed by the saloon with a U-shaped upholstered seating area with a 190 x 80 cm folding table and the galley to port. The standard equipment includes a 560-litre refrigerator with ice cube maker and a 4-burner gas cooker. The companionways to the hulls and the steering position to port are located at the front end of the saloon. Various electronic packages are available for the latter, leaving nothing to be desired.
The access door to the foredeck is practical and also increases safety. Safety is a top priority anyway. There are two electric bilge pumps in each hull, plus another in each engine compartment and a manual one. The situation is similar with the fire extinguishers. A total of seven foam extinguishers and extinguishing systems are on board in the engine compartments. There are numerous emergency escape hatches. There are two sun loungers in the foredeck and benches with a table on each side.
Choice of three to six cabins
That leaves the flybridge. Here, too, there is plenty of space. The hardtop, the hydraulically lowerable bathing platform and other extras are part of the extensive "Pack Privilège" equipment package, which costs 135,065 euros. The wetbar is located behind the stairs. It can be optionally equipped with refrigeration technology, an electric grill and a sink. On the starboard side, there is also a fully equipped helm station. It also has a manual compass, which we missed at the command centre in the saloon.
Naturally, there is a large U-shaped seating area with table on the Flybridge de Aventura. There is plenty of cushioned sunbathing space at the rear. There is a choice of three to six double cabins. The test boat has five cabins, including a very large owner's cabin with sofa and desk. All cabins are equipped with en-suite bathrooms and have headroom of at least 1.95 metres. Separate showers and pump toilets are standard. The double berths all measure around 1.93 x 1.50 metres.
Range enables Atlantic crossing with the Aventura
The motorisation in the test boat with two Yanmar LV8-320s corresponds to the basic version. The diesel engines transmit their power to the propellers via a shaft using space-saving ZF V-Drive transmissions. Yanmar diesels with 324 kW (440 hp) are also available as an option. The tank capacity is remarkable, with two 1500-litre reservoirs that can be supplemented by a further 1000-litre tank. The Aventura 14 is therefore designed for long journeys. The construction is designed for displacement cruising. The maximum speed of 11.7 kn at 3850 rpm is reached after 13 seconds.
The basic motorisation of the Aventura is therefore completely sufficient. It is many times more efficient in the speed range of 2000 rpm at a speed of 7.2 knots and an hourly consumption of 19.6 litres. This results in a range of 936 nautical miles with a 15 per cent reserve. If you reduce to 6.6 knots, the range is already around 1300 nautical miles. With an additional tank, Atlantic crossings are possible at a moderate speed. The cat is also very manoeuvrable. The Aventura 14 masters full circles at full throttle with a diameter of 2.5 boat lengths. At slow speed, the boat turns on the spot with the right throttle setting. The reaction time when reversing is three seconds. The hulls go through waves as smooth as butter and the overall seaworthiness is excellent.

Conclusion
The Aventura 14 is an independent development and not a sailboat without a mast. The catamaran is suitable for owners with large space requirements as well as for charter companies. Thanks to its good seaworthiness and high tank capacity, the yacht is ideal for long voyages. The quality level is high and the basic equipment is generous.
