Detailed Evaluation & Buyer Recommendation
Tiara Yachts 3900 Open 2013 vs Tiara Yachts 4300 Open 2010 — Same Brand, Different Boat
Matching a deep vee Tiara Yachts 3900 Open 2013 against a modified vee Tiara Yachts 4300 Open 2010 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 4300 Open 2010 measures 45,9 feet overall (2010), giving it roughly 4,0 additional feet of deck space compared to the Tiara Yachts 3900 Open 2013 at 41,9 feet (2013). Weight tells a clearer story for trailering families: the Tiara Yachts 3900 Open 2013 tips the scales at 245 lbs — 242 lbs more than the Tiara Yachts 4300 Open 2010 at 3 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 4300 Open 2010 has a 165-hp advantage over the Tiara Yachts 3900 Open 2013'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 2013 carries 535 gallons versus 6 gallons in the Tiara Yachts 4300 Open 2010. 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 4300 Open 2010 is rated for 14 passengers, while the Tiara Yachts 3900 Open 2013 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 4300 Open 2010 could be the deciding factor.
Bottom line: Choose the Tiara Yachts 4300 Open 2010 if your priority is putting more people on the water — it handles 14 passengers and at 45,9 ft it has the deck room to back that rating up comfortably. The Tiara Yachts 3900 Open 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
