When two boats share the same hull type — in this case both the Tiara Yachts 3100 Coronet 2013 and the Tiara Yachts 5800 Sovran 2011 are deep vee designs with fiberglass construction — 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 2011 measures 60,8 feet overall (2011), giving it roughly 27,7 additional feet of deck space compared to the Tiara Yachts 3100 Coronet 2013 at 33,1 feet (2013). Weight tells a clearer story for trailering families: the Tiara Yachts 3100 Coronet 2013 tips the scales at 1 355 lbs — 920 lbs more than the Tiara Yachts 5800 Sovran 2011 at 435 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 435 hp, the Tiara Yachts 5800 Sovran 2011 has a 60-hp advantage over the Tiara Yachts 3100 Coronet 2013's 375-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 5800 Sovran 2011 carries 65 gallons versus 21 gallons in the Tiara Yachts 3100 Coronet 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Tiara Yachts 3100 Coronet 2013 is rated for up to 10 people. Passenger data for the Tiara Yachts 5800 Sovran 2011 wasn't available.
