When two boats share the same hull type — in this case both the Maritime 20-DF 2009 and the Maritime 25 Defiant 2010 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Maritime 25 Defiant 2010 measures 25,7 feet overall (2010), giving it roughly 23,7 additional feet of deck space compared to the Maritime 20-DF 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Maritime 20-DF 2009 tips the scales at 204 lbs — 173 lbs more than the Maritime 25 Defiant 2010 at 31 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.
The Maritime 25 Defiant 2010 tops out at 300 hp. Engine specs for the Maritime 20-DF 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Maritime 25 Defiant 2010 carries 83 gallons versus 29 gallons in the Maritime 20-DF 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Maritime 25 Defiant 2010 is rated for 12 passengers, while the Maritime 20-DF 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maritime 25 Defiant 2010 could be the deciding factor.
Bottom line: Choose the Maritime 25 Defiant 2010 if your priority is putting more people on the water — it handles 12 passengers and at 25,7 ft it has the deck room to back that rating up comfortably. The Maritime 20-DF 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
