Sealine S29 2005 vs Sealine SC38 2007 - Boat Spec Comparison

Q: Which is the larger boat — the Sealine S29 2005 or the Sealine SC38 2007?

The Sealine SC38 2007 is the longer of the two at 37,0 feet overall. The Sealine S29 2005 comes in at 30,0 feet, making it roughly 7,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Sealine SC38 2007 is rated to a maximum of 310 hp, giving it the larger power ceiling. The Sealine S29 2005 tops out at 160 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Sealine S29 2005 is Coast Guard rated for 9 passengers, while the Sealine SC38 2007 is certified for 11. 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.

Q: Which boat is wider, and does it affect trailering?

The Sealine SC38 2007 measures 148" wide, compared to 126" for the Sealine S29 2005. 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.

Q: Which boat has the larger fuel tank — the Sealine S29 2005 or the Sealine SC38 2007?

The Sealine SC38 2007 has the bigger tank at 179 gallons, versus 126 gallons on the Sealine S29 2005. That 52-gallon difference translates to roughly 158–264 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Sealine S29 2005 and Sealine SC38 2007 from the same manufacturer?

Yes — both the Sealine S29 2005 and the Sealine SC38 2007 are built by Sealine. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Sealine S29 2005 vs Sealine SC38 2007 — Same Brand, Different Boat

The Sealine S29 2005 vs Sealine SC38 2007 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 310 hp, the Sealine SC38 2007 has a 150-hp advantage over the Sealine S29 2005's 160-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sealine SC38 2007 carries 179 gallons versus 126 gallons in the Sealine S29 2005. 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 Sealine SC38 2007 is rated for 11 passengers, while the Sealine S29 2005 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sealine SC38 2007 could be the deciding factor.

Bottom line: Choose the Sealine SC38 2007 if your priority is putting more people on the water — it handles 11 passengers and at 37,0 ft it has the deck room to back that rating up comfortably. The Sealine S29 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
