tunnel hull boat plans
Tunnel boats fly over the water on the lift created by their airfoil-shaped hulls and the air trapped and compressed between their sponsons. plus, they turn sharper than any other vehicle on water or land. the fastest outboard boats in the world are tunnels. but you don't have to be a champboat driver or formula 1 racer to enjoy a tunnelboat.. Tunnel mite is a compact replica of those exciting competition racing boats cleaning up the "silverware" on the world's racing circuit. the high speed hull rides as if on rails due to the twin, full length sponsons.. The tunnel "roof" and the upper deck surface form the lower and upper surfaces of the aerofoil, respectively. when properly designed, it is this aerofoil, and the aerodynamic lift it generates, that gives the tunnel boat its great performance. what makes the tunnel hull work? this is a multi-part article on the engineering basics of what makes. 
tunnel hull boat plans My goal in designing the pro tunnel was a hull that generates maximum aerodynamic lift in a boat meeting the gt pro weight requirement of at least 650 lbs. (boat, motor and driver), and with an expected top speed of 45-50 mph.. Pocket drive, catamaran tunnel and some theory: there are different ways to design a flats boat with minimal draft. some catamarans claim to have less draft than monohulls but that is simply not possible. let's demonstrate by comparing the geometry of two simple hulls..
