Sleek, innovative and practical!
When designing Vento RIBs a thought was primarily oriented towards the two basic goals – the vessel must have uncompromising sea keeping abilities and at the same time has to plane easily , which will affect fuel consumption and there will be no need to install big outboard engines that would not just reduce the overall purchase price but also operating costs .
These are usually contradictory characteristics because for easy planning the hulls should be shallow and this leads to the boat that will jump and slam on the waves and in this way becomes uncomfortable.
To solve this problem Vento RIBs have deep V -section hulls which start at the bow at a steep 60 degrees and finish with a deep 20 degrees stern deadrise.
Such cross section of the hull provides secure and comfortable ride in big waves (over 2 m in height). At the same time for easy planning, Vento RIBs are equipped with one step and delta pad at the stern. This design „trick“ allows the RIBs to come easily onto plane without raising the bow and with no require for powerful engines ( e.g. lightly loaded Vento 500 can plan with the outboard of 25 hp ) . The planning angle during the ride is minimal, almost horizontal even with the different load conditions on board. This reduces fuel consumption, enables better view in all directions and of course makes boating more enjoyable.
The minimum planning speed is incredibly small ( on Vento 500 only 7 knots) which means that it is possible to maintain planning regime and thus the handling of the boat in the worst possible sea conditions ( Vento 500 was tested on the waves of up to 5 m in height ) .
The tubes also contribute to the sea keeping abilities. Their pointed bow is designed for the penetration through the (high) waves.
When designing a deck it was thought primarily about practicality. Already on Vento 500 there are three rows of seats (seat in front of console, driver seat behind the console and aft bench) which is unique in this class of vessels. Larger models maintain the same scheme with even more space for more passengers.
Besides this Vento RIBs have plenty of practical storages. Vento 500 for example, can have up to 10 storages (in Smart variant) in the bow, console , seats and under the deck .
In the end, all models of Vento (even 5 meter) have static self-drainage deck (water runs out of the boat even when not in motion).

Vento inflatables are manufactured with advanced technologies from advanced materials. Rigid parts – hull, deck , console , benches – are made in so-called 3D vacuum infusion . This means that all parts, including internal bulkheads, stringers, reinforcements, frames, etc. are vacuum infused together with the basic shell which gives a much better final product. That means for example that the hull makes a unique part together with all the stringers, bulkheads and other parts and that is much stronger than when the reinforcements are laminated to the hull separately.
The technique of vacuum infusion gives around 20-30 % lighter and stronger hull than compared conventional hand laminating hull. The consequences are lower fuel consumption, better performance and better stress tolerance when riding in rough seas.
Vacuum infusion has also the environmental dimension because the whole process is performed in a closed mold and prohibits the emission of harmful fumes .
The whole boat is in sandwich construction. The hull is made from 100 % vinyl ester resin and multiaxial fibers with structural PVC foam in the middle. If necessary, the reinforcements of Kevlar and carbon fibers can be added. The construction does not have any wood that eventually might rot.
Tubes are made of Hypalon – Neoprene fabrics of 1300 g/m2 with 5 independent chambers and have a 5 year warranty. If necessary, the heavier, more robust material can be used ( for professional use ).
