Four Winns H350 2021 vs Four Winns H350 OB 2021 — Same Brand, Different Boat

The Four Winns H350 2021 vs Four Winns H350 OB 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.

On paper these two are close siblings in the size department — Four Winns H350 2021 at 35,0 ft versus Four Winns H350 OB 2021 at 35,0 ft. Weight tells a clearer story for trailering families: the Four Winns H350 OB 2021 tips the scales at 13 300 lbs — 500 lbs less than the Four Winns H350 2021 at 12 800 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 power gap is worth calling out. Rated to 800 hp, the Four Winns H350 OB 2021 has a 480-hp advantage over the Four Winns H350 2021's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 17 gal and 17 gal — so range won't be a tiebreaker here.

Both boats are rated for 10 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Four Winns H350 OB 2021 and its 800-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Four Winns H350 2021 with its 320-hp rating is the more economical daily driver.

Four Winns H350 2021 vs Four Winns H350 OB 2021 — Common Questions

Which is the larger boat — the Four Winns H350 2021 or the Four Winns H350 OB 2021?
The Four Winns H350 OB 2021 is the longer of the two at 35,0 feet overall. The Four Winns H350 2021 comes in at 35,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Four Winns H350 2021 or the Four Winns H350 OB 2021?
For trailering, the Four Winns H350 2021 has the edge at 12 800 lbs dry weight versus 13 300 lbs for the Four Winns H350 OB 2021. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Four Winns H350 OB 2021 is rated to a maximum of 800 hp, giving it the larger power ceiling. The Four Winns H350 2021 tops out at 320 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 Four Winns H350 2021 is Coast Guard rated for 10 passengers, while the Four Winns H350 OB 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Four Winns H350 2021 and Four Winns H350 OB 2021 share an 10.10 ft beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Four Winns H350 2021 and Four Winns H350 OB 2021?
Both boats carry similar fuel loads — 17 gallons and 17 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Four Winns H350 2021 and Four Winns H350 OB 2021 from the same manufacturer?
Yes — both the Four Winns H350 2021 and the Four Winns H350 OB 2021 are built by Four Winns. 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.
