Detailed Evaluation & Buyer Recommendation
Tiara Yachts 3900 Convertible 2009 vs Tiara Yachts 3900 Open 2009 — Same Brand, Different Boat
Matching a deep vee Tiara Yachts 3900 Convertible 2009 against a modified vee Tiara Yachts 3900 Open 2009 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 2009 at 39,0 ft versus Tiara Yachts 3900 Open 2009 at 39,0 ft. Weight tells a clearer story for trailering families: the Tiara Yachts 3900 Convertible 2009 tips the scales at 30 125 lbs — 29 880 lbs more than the Tiara Yachts 3900 Open 2009 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.
Both boats share a closely matched power ceiling — 600 hp for the Tiara Yachts 3900 Convertible 2009 and 600 hp for the Tiara Yachts 3900 Open 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Tiara Yachts 3900 Open 2009 carries 535 gallons versus 475 gallons in the Tiara Yachts 3900 Convertible 2009. 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 2009 and Tiara Yachts 3900 Open 2009 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.
