The Open 5,70 is meant for sailors who have experienced fun surfing on small dinghies or catamaransand want to find once again the same sensations on a small, safe sport keelboat. Therefore, re-using modern boats experience, especially the Open 5.70, the purpose was to design a boat physically and financially accessible. Finot Group implemented the technical solutions tested on the modern boats which do not increase too much the price to create a fast, alive boat.
The boat has the longest possible floating waterline (LWL) : 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.
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 "diamond" pressing on 2 small spreaders which turn with the mast. The asymmetric spinnaker is held by a retractable 5 foot bowsprit.
The control of the boat is ensured by two retractable twin rudders. The 1,75m keel can be blocked at 1,40m for the shallower waters . The deck. The large cockpit gives a lot of space for handling and allows to optimize the weight placement. The construction. The boat is built out of glass fiber reinforced polyester with a large affixed longitudinal structure which makes the connection between the deck and the hull. The deck is made of a 15mm PVC foam core sandwich.
The boat is supplied with OD Myalr Sails (Square top Main, furling jib and Asymmetrical spinnaker).
