Tri Hull

Tri Hull

It's official: Tri-Hulls are just flat-out awesome. Need proof? See picture below... When these small open-cockpit boats with their supersized engines speed into a turn, it's total chaos and that's what the drivers and fans love about this exciting class. Based on 1970s-era production boats, Tri-Hulls thrive on rough water. If it's not rough when they start racing, don-t worry - it will be by the time they're done. Boats must be original Tri-Hull design, with walk-through windshield and bow rider configuration. Tri-Hulls are an APBA-approved Sportsman (Local) class and are very popular in Texas and Louisiana. Approved Boats, Glastron V-166, Glastron V-156, Galaxy 15 ft., Thundercraft 160-SS, Cain Cutter 16 ft., Invader 15 ft., Phantom, Higgs Craft.
