The Odyssey 220C 2007 vs Odyssey Millennium 1703M 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here.

Weight tells a clearer story for trailering families: the Odyssey 220C 2007 tips the scales at 166 lbs — 151 lbs more than the Odyssey Millennium 1703M 2005 at 15 lbs. 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 1703M 2005 could be the deciding factor.
The Odyssey 220C 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Odyssey Millennium 1703M 2005 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 1703M 2005 if your priority is putting more people on the water — it handles 9 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Odyssey 220C 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
