Detailed Evaluation & Buyer Recommendation
Tiara Yachts 3900 Open 2010 vs Tiara Yachts EX 54 2023 — Same Brand, Different Boat
The Tiara Yachts 3900 Open 2010 vs Tiara Yachts EX 54 2023 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 EX 54 2023 measures 54,3 feet overall (2023), giving it roughly 12,4 additional feet of deck space compared to the Tiara Yachts 3900 Open 2010 at 41,9 feet (2010). Weight tells a clearer story for trailering families: the Tiara Yachts EX 54 2023 tips the scales at 48 400 lbs — 48 155 lbs less than the Tiara Yachts 3900 Open 2010 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 Tiara Yachts EX 54 2023 tops out at 600 hp. Engine specs for the Tiara Yachts 3900 Open 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Tiara Yachts 3900 Open 2010 carries 535 gallons versus 65 gallons in the Tiara Yachts EX 54 2023. 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 EX 54 2023 is rated for 16 passengers, while the Tiara Yachts 3900 Open 2010 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 EX 54 2023 could be the deciding factor.
Bottom line: Choose the Tiara Yachts EX 54 2023 if your priority is putting more people on the water — it handles 16 passengers and at 54,3 ft it has the deck room to back that rating up comfortably. The Tiara Yachts 3900 Open 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
