Weldcraft Marine 188 2010 vs Weldcraft Marine 21 Legacy 2013 — Same Brand, Different Boat

Matching a deep vee Weldcraft Marine 188 2010 against a modified vee Weldcraft Marine 21 Legacy 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Weldcraft Marine 188 2010 at 18,7 ft versus Weldcraft Marine 21 Legacy 2013 at 21,0 ft. Weight tells a clearer story for trailering families: the Weldcraft Marine 188 2010 tips the scales at 136 lbs — 105 lbs more than the Weldcraft Marine 21 Legacy 2013 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 Weldcraft Marine 188 2010 carries a rated maximum of 150 hp. Engine data for the Weldcraft Marine 21 Legacy 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Weldcraft Marine 21 Legacy 2013 carries 62 gallons versus 42 gallons in the Weldcraft Marine 188 2010. 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 Weldcraft Marine 21 Legacy 2013 is rated for 6 passengers, while the Weldcraft Marine 188 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Weldcraft Marine 21 Legacy 2013 could be the deciding factor.

Bottom line: Choose the Weldcraft Marine 21 Legacy 2013 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Weldcraft Marine 188 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

The Weldcraft Marine 21 Legacy 2013 is the longer of the two at 21,0 feet overall. The Weldcraft Marine 188 2010 comes in at 18,7 feet, making it roughly 2,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
