The Odyssey Cottage 1701C 2003 vs Odyssey Millennium 1703M 2003 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.
On paper these two are close siblings in the size department - Odyssey Cottage 1701C 2003 at 16,0 ft versus Odyssey Millennium 1703M 2003 at 16,0 ft. At 1 400 lbs and 1 500 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats are rated for 9 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Odyssey Cottage 1701C 2003 and Odyssey Millennium 1703M 2003 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
