Tiara Yachts 3900 Open 2011 vs Tiara Yachts 4700 Sovran 2009 — Same Brand, Different Boat

Matching a deep vee Tiara Yachts 3900 Open 2011 against a modified vee Tiara Yachts 4700 Sovran 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.

Size is the most obvious dividing line here. The Tiara Yachts 4700 Sovran 2009 measures 47,0 feet overall (2009), giving it roughly 5,1 additional feet of deck space compared to the Tiara Yachts 3900 Open 2011 at 41,9 feet (2011). Weight tells a clearer story for trailering families: the Tiara Yachts 4700 Sovran 2009 tips the scales at 3 315 lbs — 3 070 lbs less than the Tiara Yachts 3900 Open 2011 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 power gap is worth calling out. Rated to 715 hp, the Tiara Yachts 4700 Sovran 2009 has a 165-hp advantage over the Tiara Yachts 3900 Open 2011's 550-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 2011 carries 535 gallons versus 526 gallons in the Tiara Yachts 4700 Sovran 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Tiara Yachts 4700 Sovran 2009 is rated for 14 passengers, while the Tiara Yachts 3900 Open 2011 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tiara Yachts 4700 Sovran 2009 could be the deciding factor.

Bottom line: Choose the Tiara Yachts 4700 Sovran 2009 if your priority is putting more people on the water — it handles 14 passengers and at 47,0 ft it has the deck room to back that rating up comfortably. The Tiara Yachts 3900 Open 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.

Tiara Yachts 3900 Open 2011 vs Tiara Yachts 4700 Sovran 2009 — Common Questions

Which is the larger boat — the Tiara Yachts 3900 Open 2011 or the Tiara Yachts 4700 Sovran 2009?
The Tiara Yachts 4700 Sovran 2009 is the longer of the two at 47,0 feet overall. The Tiara Yachts 3900 Open 2011 comes in at 41,9 feet, making it roughly 5,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Tiara Yachts 3900 Open 2011 or the Tiara Yachts 4700 Sovran 2009?
For trailering, the Tiara Yachts 3900 Open 2011 has the edge at 245 lbs dry weight versus 3 315 lbs for the Tiara Yachts 4700 Sovran 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 4700 Sovran 2009 is rated to a maximum of 715 hp, giving it the larger power ceiling. The Tiara Yachts 3900 Open 2011 tops out at 550 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 2011 is Coast Guard rated for 12 passengers, while the Tiara Yachts 4700 Sovran 2009 is certified for 14. 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 4700 Sovran 2009 measures 174" wide, compared to 18" for the Tiara Yachts 3900 Open 2011. 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 2011 or the Tiara Yachts 4700 Sovran 2009?
The Tiara Yachts 3900 Open 2011 has the bigger tank at 535 gallons, versus 526 gallons on the Tiara Yachts 4700 Sovran 2009. That 9-gallon difference translates to roughly 27–45 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Tiara Yachts 3900 Open 2011 and Tiara Yachts 4700 Sovran 2009 from the same manufacturer?
Yes — both the Tiara Yachts 3900 Open 2011 and the Tiara Yachts 4700 Sovran 2009 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.
