Sail Boat

This design was entrusted to Studio Vallicelli & Co. in virtue of their track record. In depth research on hull shape was carried out for RIVIERA DI RIMINI in order to obtain a very low displacement (6.000 kilos) with the minimum of hull below the waterline and at the same time the highest metacentric radius. This involves a considerable righting of form.

To further increase the righting moment during offshore races, which are sailed with a minimum crew, water tanks of a capacity of 1.100 litres each were installed which function as ballast. 


A simple and efficient system
 of valves permits taking on, discharging and moving the ballast water both by gravity and by an electric pump with a delivery of around 250 litres/minute. 
The lead fin keel is linked to a high Aspect Ratio wing (maximum tie is 75 cm) fixed to the coach roof to further reduce the weight of the structure.

The RIVIERA DI RIMINI sail 
plan has a battened, very lengthened mainsail and a curving of 35%; a genoa cut max. 135% which permits the reduction of mainsail overlap and therefore improved efficiency; 
a light genoa with halyard at the masthead and tack on the bowsprit of 2.50 metres, spinnaker and gennaker at the masthead and half-mast. 
The laminations and structures, which have also been calculated with Finished Elements programmes, are in termanto sandwich and unidirectional carbon fibres impregnated with epoxy resin. 
All the chain-plates are in carbon fibre.
