The NEEL trimarans are resolutely designed for fast cruising, regularly sailing at more than 10 knots average, thus covering 220 miles per 24 hours. 15 to 20 knots are often reached as soon as the wind strengthen.
The NEEL trimarans are set up with the last innovations developed by racing multihulls, such as square top mainsail, Vectran shrouds and forestay, reef hooks, genoa stocker, carbon rudder…Weight distribution is centered, limiting pitching.
The main hull roach facilitates tacking. On the other hand, the floats shape is tense in order to favour stability and hull center progress according to the sail loading.
The sail area is wide with 170sqm per ton. Finally, the trimaran is also fast under power. Indeed, the main hull prismatic coefficient offers a very low drag. Moreover, the lateral floats are touching only very lightly the water surface.
Dedicated computer study for optimized construction
In order to optimize the NEEL trimarans structure, we hired TENSYL company, with whom we had already worked for the racing trimaran TRILOGIC. TENSYL specialized in structural calculation of racing and cruising composite multihulls.
The laminate is determined by considering the sea loading cases which are the most critical for the boat structure: boat surfing a wave at full speed or crossbeam navigation.
The analysis programs transmit the needed informations which are then compared to requirements acceptable ones.
The color views are particularly useful to identify the confine areas to strengthen. The body of evidence aims to define, for each zone, the most suitable construction materials and the quantities required. The purpose is to eliminate useless weights and to apply
security coefficients suited to the effort zones.
