Both the Venture Marine 34 Forward Seating 2009 and the Venture Marine 39 Open 2010 are deep-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 Venture Marine 39 Open 2010 measures 39,5 feet overall (2010), giving it roughly 5,0 additional feet of deck space compared to the Venture Marine 34 Forward Seating 2009 at 34,5 feet (2009). Weight tells a clearer story for trailering families: the Venture Marine 39 Open 2010 tips the scales at 8 000 lbs - 1 100 lbs less than the Venture Marine 34 Forward Seating 2009 at 6 900 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.
For family outings this is probably the sharpest distinction between the two. The Venture Marine 39 Open 2010 is rated for 12 passengers, while the Venture Marine 34 Forward Seating 2009 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Venture Marine 39 Open 2010 could be the deciding factor.
Bottom line: Choose the Venture Marine 39 Open 2010 if your priority is putting more people on the water - it handles 12 passengers and at 39,5 ft it has the deck room to back that rating up comfortably. The Venture Marine 34 Forward Seating 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
