Four Winns H310 2011 vs Four Winns V378 2009: Which Modified-V Boat Fits Your Needs?

Both the Four Winns H310 2011 and the Four Winns V378 2009 are modified-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Four Winns V378 2009 measures 37,0 feet overall (2009), giving it roughly 5,7 additional feet of deck space compared to the Four Winns H310 2011 at 31,3 feet (2011). Weight tells a clearer story for trailering families: the Four Winns V378 2009 tips the scales at 20 800 lbs - 12 440 lbs less than the Four Winns H310 2011 at 8 360 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 550 hp, the Four Winns V378 2009 has a 230-hp advantage over the Four Winns H310 2011's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Four Winns V378 2009 carries 300 gallons versus 130 gallons in the Four Winns H310 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 14 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: The Four Winns V378 2009 at 37,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Four Winns H310 2011 at 31,3 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.

Four Winns H310 2011 vs Four Winns V378 2009 - Common Questions

Which is the larger boat - the Four Winns H310 2011 or the Four Winns V378 2009?
The Four Winns V378 2009 is the longer of the two at 37,0 feet overall. The Four Winns H310 2011 comes in at 31,3 feet, making it roughly 5,7 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Four Winns H310 2011 or the Four Winns V378 2009?
For trailering, the Four Winns H310 2011 has the edge at 8 360 lbs dry weight versus 20 800 lbs for the Four Winns V378 2009. 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 V378 2009 is rated to a maximum of 550 hp, giving it the larger power ceiling. The Four Winns H310 2011 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 H310 2011 is Coast Guard rated for 14 passengers, while the Four Winns V378 2009 is certified for 14. 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 V378 2009 measures 153" wide, compared to 116" for the Four Winns H310 2011. 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 H310 2011 or the Four Winns V378 2009?
The Four Winns V378 2009 has the bigger tank at 300 gallons, versus 130 gallons on the Four Winns H310 2011. That 170-gallon difference translates to roughly 510–850 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Four Winns H310 2011 and Four Winns V378 2009 from the same manufacturer?
Yes - both the Four Winns H310 2011 and the Four Winns V378 2009 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.
