Tiara Yachts 3800 Open 2007 vs Tiara Yachts 4700 Sovran 2009 — Same Brand, Different Boat

The Tiara Yachts 3800 Open 2007 vs Tiara Yachts 4700 Sovran 2009 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 4700 Sovran 2009 measures 47,0 feet overall (2009), giving it roughly 43,0 additional feet of deck space compared to the Tiara Yachts 3800 Open 2007 at 4,0 feet (2007). Weight tells a clearer story for trailering families: the Tiara Yachts 4700 Sovran 2009 tips the scales at 3 315 lbs — 3 089 lbs less than the Tiara Yachts 3800 Open 2007 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 power gap is worth calling out. Rated to 715 hp, the Tiara Yachts 4700 Sovran 2009 has a 225-hp advantage over the Tiara Yachts 3800 Open 2007's 490-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 4700 Sovran 2009 carries 526 gallons versus 411 gallons in the Tiara Yachts 3800 Open 2007. 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 3800 Open 2007 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 3800 Open 2007 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 3800 Open 2007 vs Tiara Yachts 4700 Sovran 2009 — Common Questions

Which is the larger boat — the Tiara Yachts 3800 Open 2007 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 3800 Open 2007 comes in at 4,0 feet, making it roughly 43,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Tiara Yachts 3800 Open 2007 or the Tiara Yachts 4700 Sovran 2009?
For trailering, the Tiara Yachts 3800 Open 2007 has the edge at 226 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 3800 Open 2007 tops out at 490 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 3800 Open 2007 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 17" for the Tiara Yachts 3800 Open 2007. 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 3800 Open 2007 or the Tiara Yachts 4700 Sovran 2009?
The Tiara Yachts 4700 Sovran 2009 has the bigger tank at 526 gallons, versus 411 gallons on the Tiara Yachts 3800 Open 2007. That 115-gallon difference translates to roughly 345–575 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Tiara Yachts 3800 Open 2007 and Tiara Yachts 4700 Sovran 2009 from the same manufacturer?
Yes — both the Tiara Yachts 3800 Open 2007 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.
