Detailed Evaluation & Buyer Recommendation
Tiara Yachts 3800 Open 2008 vs Tiara Yachts 3900 Convertible 2010 — Same Brand, Different Boat
Matching a modified vee Tiara Yachts 3800 Open 2008 against a deep vee Tiara Yachts 3900 Convertible 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 Convertible 2010 measures 41,6 feet overall (2010), giving it roughly 3,6 additional feet of deck space compared to the Tiara Yachts 3800 Open 2008 at 38,0 feet (2008). Weight tells a clearer story for trailering families: the Tiara Yachts 3900 Convertible 2010 tips the scales at 30 125 lbs — 29 899 lbs less than the Tiara Yachts 3800 Open 2008 at 226 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 3800 Open 2008 carries a rated maximum of 490 hp. Engine data for the Tiara Yachts 3900 Convertible 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 Convertible 2010 carries 475 gallons versus 411 gallons in the Tiara Yachts 3800 Open 2008. 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 2010 at 41,6 ft is the right call if deck space, comfort, and entertaining are top of your list. The Tiara Yachts 3800 Open 2008 at 38,0 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.
