2016 Nitro Z18, The all-new 2016 NITRO Z18 takes the success of the highly-regarded Z-7 bass boat to a whole new level. Our new NVT (NITRO Vortex Technology) hull. Lower profile gunnels for maximum deck space. An improved, heavily-insulated cooler. Room at the bow and console for a 12" fishfinder. These improvements, plus the high level of quality craftsmanship that goes into every NITRO, make the new Z18 the fiberglass bass boat of choice for everyone from the weekend warrior to the hardcore tournament contender.
