That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Odyssey 222C TT I/O 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Odyssey Millennium 1903M 2004 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Odyssey 222C TT I/O 2007 if your priority is putting more people on the water — it handles 13 passengers and at 23,0 ft it has the deck room to back that rating up comfortably.
