If you live to make wading pools out of mad rivers, this is the jet boat you've been waiting for. Built using our exclusive Pre-Flex technology with a heavily reinforced hull with nine 6061 extruded stringers, 3/8-inch 6061 center keel, 1/4 inch transom reinforcing and 6061 bottom with UHMW armor. The 2008 1775 Extreme Duty is unbelievably agile and flexible, thanks to its parabolic hull design. In other words, it's a jet boat that's destined to redefine river boating - one rapid at a time.
