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.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Odyssey Millennium 2503M 2004 could be the deciding factor.
The Odyssey 216F 2006 is an inflatable design - lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Odyssey Millennium 2503M 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 Millennium 2503M 2004 if your priority is putting more people on the water - it handles 17 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Odyssey 216F 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
