Both the Tiara Yachts 3600 Open IPS 2009 and the Tiara Yachts 5800 Sovran 2010 are modified-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Tiara Yachts 5800 Sovran 2010 measures 60,8 feet overall (2010), giving it roughly 24,8 additional feet of deck space compared to the Tiara Yachts 3600 Open IPS 2009 at 36,0 feet (2009). Weight tells a clearer story for trailering families: the Tiara Yachts 5800 Sovran 2010 tips the scales at 43 500 lbs - 24 400 lbs less than the Tiara Yachts 3600 Open IPS 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.
