The Odyssey 175NS 2005 vs Odyssey 220C 2006 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.
Both boats share a closely matched power ceiling — 75 hp for the Odyssey 175NS 2005 and 90 hp for the Odyssey 220C 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The Odyssey 220C 2006 is rated for 10 passengers, while the Odyssey 175NS 2005 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Odyssey 220C 2006 could be the deciding factor.
The Odyssey 220C 2006 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Odyssey 175NS 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 220C 2006 if your priority is putting more people on the water — it handles 10 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Odyssey 175NS 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
