Sealine F42/5 2005 vs Sealine T50 2011 - Boat Spec Comparison

Q: Which is the larger boat — the Sealine F42/5 2005 or the Sealine T50 2011?

The Sealine T50 2011 is the longer of the two at 50,5 feet overall. The Sealine F42/5 2005 comes in at 44,9 feet, making it roughly 5,7 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Sealine T50 2011 is rated to a maximum of 575 hp, giving it the larger power ceiling. The Sealine F42/5 2005 tops out at 400 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 F42/5 2005 is Coast Guard rated for 13 passengers, while the Sealine T50 2011 is certified for 15. 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 T50 2011 measures 181" wide, compared to 166" for the Sealine F42/5 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 F42/5 2005 or the Sealine T50 2011?

The Sealine T50 2011 has the bigger tank at 549 gallons, versus 370 gallons on the Sealine F42/5 2005. That 179-gallon difference translates to roughly 538–897 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Sealine F42/5 2005 and Sealine T50 2011 from the same manufacturer?

Yes — both the Sealine F42/5 2005 and the Sealine T50 2011 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 F42/5 2005 vs Sealine T50 2011 — Same Brand, Different Boat

The Sealine F42/5 2005 vs Sealine T50 2011 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 575 hp, the Sealine T50 2011 has a 175-hp advantage over the Sealine F42/5 2005's 400-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 T50 2011 carries 549 gallons versus 370 gallons in the Sealine F42/5 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 T50 2011 is rated for 15 passengers, while the Sealine F42/5 2005 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sealine T50 2011 could be the deciding factor.

Bottom line: Choose the Sealine T50 2011 if your priority is putting more people on the water — it handles 15 passengers and at 50,5 ft it has the deck room to back that rating up comfortably. The Sealine F42/5 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
