Detailed Evaluation & Buyer Recommendation

Tiara Yachts 3100 Open 2011 vs Tiara Yachts 3900 Sovran 2010 — Same Brand, Different Boat

Matching a deep vee Tiara Yachts 3100 Open 2011 against a modified vee Tiara Yachts 3900 Sovran 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Tiara Yachts 3900 Sovran 2010 measures 39,3 feet overall (2010), giving it roughly 6,3 additional feet of deck space compared to the Tiara Yachts 3100 Open 2011 at 33,0 feet (2011). Weight tells a clearer story for trailering families: the Tiara Yachts 3100 Open 2011 tips the scales at 13 225 lbs — 13 202 lbs more than the Tiara Yachts 3900 Sovran 2010 at 23 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 Tiara Yachts 3100 Open 2011 carries a rated maximum of 375 hp. Engine data for the Tiara Yachts 3900 Sovran 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Tiara Yachts 3100 Open 2011 carries 21 gallons versus 3 gallons in the Tiara Yachts 3900 Sovran 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Tiara Yachts 3100 Open 2011 is rated for up to 10 people. Passenger data for the Tiara Yachts 3900 Sovran 2010 wasn't available.

Bottom line: The Tiara Yachts 3900 Sovran 2010 at 39,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Tiara Yachts 3100 Open 2011 at 33,0 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.
