Four Winns H6 OB 2023 vs Four Winns HD5 RS Surf 2021 - Boat Spec Comparison

Q: Which is the larger boat — the Four Winns H6 OB 2023 or the Four Winns HD5 RS Surf 2021?

The Four Winns HD5 RS Surf 2021 is the longer of the two at 26,3 feet overall. The Four Winns H6 OB 2023 comes in at 26,2 feet, making it roughly 0,1 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: How many people can each boat hold?

The Four Winns H6 OB 2023 is Coast Guard rated for 7 passengers, while the Four Winns HD5 RS Surf 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.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Four Winns H6 OB 2023 and Four Winns HD5 RS Surf 2021 share an 8.50 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.

Q: Which boat has the larger fuel tank — the Four Winns H6 OB 2023 or the Four Winns HD5 RS Surf 2021?

The Four Winns HD5 RS Surf 2021 has the bigger tank at 55 gallons, versus 1 gallons on the Four Winns H6 OB 2023. That 54-gallon difference translates to roughly 162–270 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Four Winns H6 OB 2023 and Four Winns HD5 RS Surf 2021 from the same manufacturer?

Yes — both the Four Winns H6 OB 2023 and the Four Winns HD5 RS Surf 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.
