Sealine F42/5 2005 vs Sealine S335V 2021 — Same Brand, Different Boat

The Sealine F42/5 2005 vs Sealine S335V 2021 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 400 hp, the Sealine F42/5 2005 has a 100-hp advantage over the Sealine S335V 2021's 300-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 F42/5 2005 carries 370 gallons versus 125 gallons in the Sealine S335V 2021. 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 F42/5 2005 is rated for 13 passengers, while the Sealine S335V 2021 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sealine F42/5 2005 could be the deciding factor.

Bottom line: Choose the Sealine F42/5 2005 if your priority is putting more people on the water — it handles 13 passengers and at 44,9 ft it has the deck room to back that rating up comfortably. The Sealine S335V 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

Sealine F42/5 2005 vs Sealine S335V 2021 — Common Questions

Which is the larger boat — the Sealine F42/5 2005 or the Sealine S335V 2021?
The Sealine F42/5 2005 is the longer of the two at 44,9 feet overall. The Sealine S335V 2021 comes in at 33,1 feet, making it roughly 11,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Sealine F42/5 2005 is rated to a maximum of 400 hp, giving it the larger power ceiling. The Sealine S335V 2021 tops out at 300 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.
How many people can each boat hold?
The Sealine F42/5 2005 is Coast Guard rated for 13 passengers, while the Sealine S335V 2021 is certified for 10. 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.
Which boat is wider, and does it affect trailering?
The Sealine F42/5 2005 measures 166" wide, compared to 139" for the Sealine S335V 2021. 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.
Which boat has the larger fuel tank — the Sealine F42/5 2005 or the Sealine S335V 2021?
The Sealine F42/5 2005 has the bigger tank at 370 gallons, versus 125 gallons on the Sealine S335V 2021. That 244-gallon difference translates to roughly 734–1224 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sealine F42/5 2005 and Sealine S335V 2021 from the same manufacturer?
Yes — both the Sealine F42/5 2005 and the Sealine S335V 2021 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.
