When two boats share the same hull type — in this case both the Maritime 20 Classic 2011 and the Maritime 25 Defiant 2011 are modified vee designs with composite 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 2011 measures 25,7 feet overall (2011), giving it roughly 5,1 additional feet of deck space compared to the Maritime 20 Classic 2011 at 20,6 feet (2011). At 21 lbs and 31 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.
The power gap is worth calling out. Rated to 300 hp, the Maritime 25 Defiant 2011 has a 150-hp advantage over the Maritime 20 Classic 2011's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Maritime 25 Defiant 2011 carries 83 gallons versus 29 gallons in the Maritime 20 Classic 2011. 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 2011 is rated for 12 passengers, while the Maritime 20 Classic 2011 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 2011 could be the deciding factor.
Bottom line: Choose the Maritime 25 Defiant 2011 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 Classic 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
