Also available: cockpit plans can be adapted to the pro tunnel. i built the original dillon pro tunnel in the winter of 2009 and sold the bare hull to another member of our twin city powerboat racing club.. Taking the jonboat concept further, i got an email from a boating enthusiast asking if i had ever designed a tunnel hull boat along the lines of the swamper. he indicated that he had seen a boat something like that which had been designed for very thin water work.. Mod vp simply refers to a specific race class (vee production). you see many larger catamarans with a true 2 sponson tunnel design (referred to as asymmetrical tunnels) but it’s rare for small pleasure boats. f1 style race boats are a true tunnel hull (air entrapment) as well but that design has many drawbacks for pleasure use..
