Detailed Evaluation & Buyer Recommendation
Tiara Yachts 3800 Open 2006 vs Tiara Yachts 3900 Convertible 2006 — Same Brand, Different Boat
The Tiara Yachts 3800 Open 2006 vs Tiara Yachts 3900 Convertible 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Tiara Yachts 3900 Convertible 2006 measures 41,0 feet overall (2006), giving it roughly 37,0 additional feet of deck space compared to the Tiara Yachts 3800 Open 2006 at 4,0 feet (2006). Weight tells a clearer story for trailering families: the Tiara Yachts 3900 Convertible 2006 tips the scales at 30 125 lbs — 29 899 lbs less than the Tiara Yachts 3800 Open 2006 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 3900 Convertible 2006 tops out at 9 hp. Engine specs for the Tiara Yachts 3800 Open 2006 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Tiara Yachts 3900 Convertible 2006 carries 475 gallons versus 411 gallons in the Tiara Yachts 3800 Open 2006. 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 2006 at 41,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Tiara Yachts 3800 Open 2006 at 4,0 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.
