Razor is a full-size Laser ILCA 7, the single-handed dinghy sailed at the Olympics. It is a small experiment next to the big ocean racers: a real 4.23 m hull with every measurement the ILCA class rules give, from the daggerboard and rudder to the mast sections and the deck fittings. Hull & appendages A 4.23 m hull that is 1.39 m wide, with a rule-size daggerboard (0.78 m draft) and a kick-up style rudder on stainless pintles. The hull shape is not public, so it was traced from a side drawing and tuned until the waterline length matched the real boat. Rig & sail A two-piece carbon-look mast of 6.1 m that turns with the boom, as on the real boat, and an ILCA 7 mainsail of about 7 m² with the "Razor" graphic: gold dots on black with the cut through the name, like the sails of its sisters. Deck & cockpit A clean deck with only what the class rules ask for: hiking strap, grab rails along the cockpit, mast step and daggerboard pad. Two carbon pods next to the daggerboard hold the sail instruments, and the twin-blade logo sits on the foredeck. Sail it Light, quick and wet: you steer with the tiller extension and keep the boat flat with your weight. A different way to sail in Sailaway, between the ocean passages. Built entirely from parametric code in Blender. Feedback is always welcome. carlo.cifarelli@gmail.com |
