Matching a modified vee Tiara Yachts 3800 Open 2009 against a deep vee Tiara Yachts 3900 Open 2013 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 3900 Open 2013 measures 41,9 feet overall (2013), giving it roughly 3,9 additional feet of deck space compared to the Tiara Yachts 3800 Open 2009 at 38,0 feet (2009). At 226 lbs and 245 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 550 hp, the Tiara Yachts 3900 Open 2013 has a 60-hp advantage over the Tiara Yachts 3800 Open 2009'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 3900 Open 2013 carries 535 gallons versus 411 gallons in the Tiara Yachts 3800 Open 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
