The Tiara Yachts 3600 Open 2009 is a modified-V design and the Tiara Yachts 4500 Sovran 2011 is a deep-V design, so you're likely deciding between two noticeably 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 4500 Sovran 2011 measures 46,8 feet overall (2011), giving it roughly 10,8 additional feet of deck space compared to the Tiara Yachts 3600 Open 2009 at 36,0 feet (2009). Weight tells a clearer story for trailering families: the Tiara Yachts 4500 Sovran 2011 tips the scales at 26 700 lbs - 7 600 lbs less than the Tiara Yachts 3600 Open 2009 at 19 100 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.

Both boats share a closely matched power ceiling - 425 hp for the Tiara Yachts 3600 Open 2009 and 435 hp for the Tiara Yachts 4500 Sovran 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Tiara Yachts 3600 Open 2009 carries 400 gallons versus 350 gallons in the Tiara Yachts 4500 Sovran 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
