Extreme SIB - Gemini Dive 470
Their is also a 5.3m version of this boat.
A If you fit launching wheels, 2 people could easily launch and recover it.
A Mine is rated for up to 80hp, but the Yamaha 40 pushes it along quite nicely with 3-4 people and moderate gear. While it can be inflated & deflated with each use and loaded in a pickup truck, a flat deck trailer is far more convenient.
A About 1/2 the price of a Zodiac Futura Commando 470. The Gemini is simpler in design but much better built and with a far more efficient hull design.
Before my purchase, I did alot of research and looked at dozens of different SIBS from various manufacturers (I also own a couple of zodiac SIBs - one from the recreational line, the other from their mil-pro line) and have yet to see another SIB built anywhere near as well as this one. It also rides more smoothly than any 16 foot or shorter hardhull that I've ridden in.
