The Open 5,70 is designed for sailing schools, renting, clubs and to be used by young people with a reduced surveillance and, in regatta, by anybody who have passed the age for dinghy acrobatics.

This style of boat, successor of the Star, the Aile or the Soling, is a tradition abroad. In France, until now, keel day-boat sales are limited. In this size, for day race or day ride, the sailors use 5,5 to 6,5 m cruising boats. It is an expensive solution, and slow

Therefore, re-using our modern boats experience, especially the Open 7,50, our purpose was to design a boat physically and financially accessible. We implemented the technical solutions tested on the modern boats which do not increase too much the price to create a fast, alive boat. .

Caracteristics

Sails

The hull.

The boat has the longest possible floating waterline : 5,70 m. The waterline remains narrow to decrease the wet area but width of the boat is at the maximum of the road size (2,55m). The stability of shape, stability of weight give a stable boat which can carry large sail areas with good performance both upwind and downwind.

The ballast.

It consists of a glass injected fin (30 kg) and a lead bulb of 150 kg with two settings for a draft of 1,75 m or 1,45 m. It gives a very low center of gravity. .

The sail plan.

With a high aspect ratio, it consists of a small jib and a large mainsail controlled by a main track. The pivoting wingmast is held by a forestay and a 2 shrouds aft. . The tension of the rigging is set by a bolt jack placed under the mast. The stability of the mast is completed by a "losange" pressing on 2 small spreaders which turn with the mast. The asymmetric spinnaker is held by an telescopic boomsprit.

The appendage.

The control of the boat is ensured by two retractable rudders. The 1,75m keel can be blocked at 1,40m for the shallower waters .
