Matching a modified vee Tiara Yachts 3900 Open 2009 against a deep vee Tiara Yachts 4800 Convertible 2012 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 4800 Convertible 2012 measures 51,4 feet overall (2012), giving it roughly 12,4 additional feet of deck space compared to the Tiara Yachts 3900 Open 2009 at 39,0 feet (2009). Weight tells a clearer story for trailering families: the Tiara Yachts 4800 Convertible 2012 tips the scales at 45 012 lbs — 44 767 lbs less than the Tiara Yachts 3900 Open 2009 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 1 015 hp, the Tiara Yachts 4800 Convertible 2012 has a 415-hp advantage over the Tiara Yachts 3900 Open 2009's 600-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 1 gallons in the Tiara Yachts 4800 Convertible 2012. 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 4800 Convertible 2012 is rated for 15 passengers, while the Tiara Yachts 3900 Open 2009 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 4800 Convertible 2012 could be the deciding factor.
