The new foil designs allowed for enough lift a portion of the boat out of the water, making it a partially foiling boat, reducing the overall drag and increasing the top speed of the boat. Certainly making the rest of us old guys look bad;). A measure of the power of the sails relative to the weight of the boat. 'T' Foils, commonly seen in the International Moth class and the AC75 class, contains a vertical component connecting to a horizontal wing, providing lift for the foil. Using the best possible manufacturing techniques available, weve obtained maximum strength with minimum weight using autoclave technology, curing the pre-impregnated carbon/epoxy at 120 degrees Celsius at an atmospheric pressure of 6 bar. 2023 Sea Time Tech, LLC.
