Tiara Yachts 3900 Open 2009 vs Tiara Yachts 3900 Sovran 2007 — Same Brand, Different Boat

The Tiara Yachts 3900 Open 2009 vs Tiara Yachts 3900 Sovran 2007 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.

On paper these two are close siblings in the size department — Tiara Yachts 3900 Open 2009 at 39,0 ft versus Tiara Yachts 3900 Sovran 2007 at 41,0 ft. Weight tells a clearer story for trailering families: the Tiara Yachts 3900 Open 2009 tips the scales at 245 lbs — 222 lbs more than the Tiara Yachts 3900 Sovran 2007 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 power gap is worth calling out. Rated to 600 hp, the Tiara Yachts 3900 Open 2009 has a 230-hp advantage over the Tiara Yachts 3900 Sovran 2007's 370-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Tiara Yachts 3900 Open 2009 carries 535 gallons versus 3 gallons in the Tiara Yachts 3900 Sovran 2007. 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: Performance buyers should lean toward the Tiara Yachts 3900 Open 2009 and its 600-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Tiara Yachts 3900 Sovran 2007 with its 370-hp rating is the more economical daily driver.

Tiara Yachts 3900 Open 2009 vs Tiara Yachts 3900 Sovran 2007 — Common Questions

Which is the larger boat — the Tiara Yachts 3900 Open 2009 or the Tiara Yachts 3900 Sovran 2007?
The Tiara Yachts 3900 Sovran 2007 is the longer of the two at 41,0 feet overall. The Tiara Yachts 3900 Open 2009 comes in at 39,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Tiara Yachts 3900 Open 2009 or the Tiara Yachts 3900 Sovran 2007?
For trailering, the Tiara Yachts 3900 Sovran 2007 has the edge at 23 lbs dry weight versus 245 lbs for the Tiara Yachts 3900 Open 2009. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Tiara Yachts 3900 Open 2009 is rated to a maximum of 600 hp, giving it the larger power ceiling. The Tiara Yachts 3900 Sovran 2007 tops out at 370 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Tiara Yachts 3900 Open 2009 is Coast Guard rated for 12 passengers, while the Tiara Yachts 3900 Sovran 2007 is certified for 12. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Tiara Yachts 3900 Sovran 2007 measures 167" wide, compared to 18" for the Tiara Yachts 3900 Open 2009. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Tiara Yachts 3900 Open 2009 or the Tiara Yachts 3900 Sovran 2007?
The Tiara Yachts 3900 Open 2009 has the bigger tank at 535 gallons, versus 3 gallons on the Tiara Yachts 3900 Sovran 2007. That 532-gallon difference translates to roughly 1596–2660 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Tiara Yachts 3900 Open 2009 and Tiara Yachts 3900 Sovran 2007 from the same manufacturer?
Yes — both the Tiara Yachts 3900 Open 2009 and the Tiara Yachts 3900 Sovran 2007 are built by Tiara Yachts. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
