The Wellcraft 3700 Martinique 2001 vs Wellcraft 390 2004 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.

The power gap is worth calling out. Rated to 480 hp, the Wellcraft 390 2004 has a 100-hp advantage over the Wellcraft 3700 Martinique 2001's 380-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Wellcraft 390 2004 carries 394 gallons versus 288 gallons in the Wellcraft 3700 Martinique 2001. 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 Wellcraft 3700 Martinique 2001 is rated for 11 passengers, while the Wellcraft 390 2004 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Wellcraft 3700 Martinique 2001 could be the deciding factor.
