Weldcraft Marine 18 SJ 2010 vs Weldcraft Marine 240 SD 2010 — Which Deep Vee Fits Your Needs?

When two boats share the same hull type — in this case both the Weldcraft Marine 18 SJ 2010 and the Weldcraft Marine 240 SD 2010 are deep vee designs with aluminum 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?

For family outings this is probably the sharpest distinction between the two. The Weldcraft Marine 240 SD 2010 is rated for 7 passengers, while the Weldcraft Marine 18 SJ 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Weldcraft Marine 240 SD 2010 could be the deciding factor.

Bottom line: Choose the Weldcraft Marine 240 SD 2010 if your priority is putting more people on the water — it handles 7 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Weldcraft Marine 18 SJ 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

The Weldcraft Marine 240 SD 2010 is the longer of the two at 24,0 feet overall. The Weldcraft Marine 18 SJ 2010 comes in at 18,1 feet, making it roughly 5,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
How many people can each boat hold?
The Weldcraft Marine 18 SJ 2010 is Coast Guard rated for 6 passengers, while the Weldcraft Marine 240 SD 2010 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

The Weldcraft Marine 240 SD 2010 measures 102" wide, compared to 86" for the Weldcraft Marine 18 SJ 2010. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

The Weldcraft Marine 240 SD 2010 has the bigger tank at 62 gallons, versus 42 gallons on the Weldcraft Marine 18 SJ 2010. That 20-gallon difference translates to roughly 60–100 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
