Four Winns H350 2021 vs Four Winns HD8 RS 2021 — Same Brand, Different Boat

The Four Winns H350 2021 vs Four Winns HD8 RS 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.

Size is the most obvious dividing line here. The Four Winns H350 2021 measures 35,0 feet overall (2021), giving it roughly 8,5 additional feet of deck space compared to the Four Winns HD8 RS 2021 at 26,5 feet (2021). Weight tells a clearer story for trailering families: the Four Winns H350 2021 tips the scales at 12 800 lbs — 8 550 lbs more than the Four Winns HD8 RS 2021 at 4 250 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.

Both boats share a closely matched power ceiling — 320 hp for the Four Winns H350 2021 and 300 hp for the Four Winns HD8 RS 2021. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Four Winns H350 2021 carries 17 gallons versus 7 gallons in the Four Winns HD8 RS 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 Four Winns H350 2021 is rated for 10 passengers, while the Four Winns HD8 RS 2021 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Four Winns H350 2021 could be the deciding factor.

Bottom line: Choose the Four Winns H350 2021 if your priority is putting more people on the water — it handles 10 passengers and at 35,0 ft it has the deck room to back that rating up comfortably. The Four Winns HD8 RS 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

Four Winns H350 2021 vs Four Winns HD8 RS 2021 — Common Questions

Which is the larger boat — the Four Winns H350 2021 or the Four Winns HD8 RS 2021?
The Four Winns H350 2021 is the longer of the two at 35,0 feet overall. The Four Winns HD8 RS 2021 comes in at 26,5 feet, making it roughly 8,5 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 HD8 RS 2021?
For trailering, the Four Winns HD8 RS 2021 has the edge at 4 250 lbs dry weight versus 12 800 lbs for the Four Winns H350 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 2021 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Four Winns HD8 RS 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 Four Winns H350 2021 is Coast Guard rated for 10 passengers, while the Four Winns HD8 RS 2021 is certified for 8. 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 Four Winns HD8 RS 2021 measures 1 212" wide, compared to 121" for the Four Winns H350 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 Four Winns H350 2021 or the Four Winns HD8 RS 2021?
The Four Winns H350 2021 has the bigger tank at 17 gallons, versus 7 gallons on the Four Winns HD8 RS 2021. That 10-gallon difference translates to roughly 30–50 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Four Winns H350 2021 and Four Winns HD8 RS 2021 from the same manufacturer?
Yes — both the Four Winns H350 2021 and the Four Winns HD8 RS 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.
