Dean Catamarans, begin their production in 1984.
This invaluable experiment was forged in the seas of South Africa where the winds can vary from 10 to 60 nodes in a few minutes and from an oil sea "" to waves up to 17 meters recorded
Certain large building sites of catamarans produce mainly boats for fleets of charter in the world and do not have the freedom of design which we have, and as usually these fleets operate in protected water, the navigability is often a forgotten factor.
All the Dean Catamarans, have the characteristics to have a very stable full stem, with a front bridge into hard, very advanced and small trampolines.
This ensures that the stem of the boat does not plow in the strong seas and in the heavy seas coming from the back the stem does not charge, this draws aside the possibility of sancir. The stems with fine entries and large trampolines do not enjoy the same safety factor.
Many nacelles of catamarans type, that is caused by the interaction waves created by the boat in the tunnel of its hulls, particularly when the hulls are symmetrical (equal curves on each side of the hulls). All the Dean catamarans have asymmetrical hulls, and the external curve is much more important than the interior curve, which reduces the wave induced by the hulls (reduction of the venturi effect). This, coupled to a high and broad nacelle, reduced considerably the possibilities with the nacelle of typing, ensuring of more than better performances.
The chechmates of the Dean catamarans have a search of 7 degrees. This unusual characteristic facilitates at the same time the yacht to be gone up with the wind and to transfer without any the encountered difficulties not some other catamarans.
