Four Winns H350 2021 vs Four Winns HD3 OB 2022 — Same Brand, Different Boat

The Four Winns H350 2021 vs Four Winns HD3 OB 2022 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 12,9 additional feet of deck space compared to the Four Winns HD3 OB 2022 at 22,1 feet (2022). Weight tells a clearer story for trailering families: the Four Winns H350 2021 tips the scales at 12 800 lbs — 8 610 lbs more than the Four Winns HD3 OB 2022 at 4 190 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 Four Winns H350 2021 carries a rated maximum of 320 hp. Engine data for the Four Winns HD3 OB 2022 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Four Winns HD3 OB 2022 carries 44 gallons versus 17 gallons in the Four Winns H350 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 HD3 OB 2022 caps at 6. 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 HD3 OB 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

The Four Winns H350 2021 is the longer of the two at 35,0 feet overall. The Four Winns HD3 OB 2022 comes in at 22,1 feet, making it roughly 12,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
