Tiara Yachts 3900 Convertible 2013 vs Tiara Yachts 3900 Open 2010 — Same Brand, Different Boat

Matching a deep vee Tiara Yachts 3900 Convertible 2013 against a modified vee Tiara Yachts 3900 Open 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.

On paper these two are close siblings in the size department — Tiara Yachts 3900 Convertible 2013 at 41,6 ft versus Tiara Yachts 3900 Open 2010 at 41,9 ft. Weight tells a clearer story for trailering families: the Tiara Yachts 3900 Convertible 2013 tips the scales at 30 125 lbs — 29 880 lbs more than the Tiara Yachts 3900 Open 2010 at 245 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 3900 Convertible 2013 carries a rated maximum of 550 hp. Engine data for the Tiara Yachts 3900 Open 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 3900 Open 2010 carries 535 gallons versus 475 gallons in the Tiara Yachts 3900 Convertible 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 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 Tiara Yachts 3900 Convertible 2013 and Tiara Yachts 3900 Open 2010 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
