When two boats share the same hull type — in this case both the Tiara Yachts 3100 Open 2011 and the Tiara Yachts 3200 Open 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?

On paper these two are close siblings in the size department — Tiara Yachts 3100 Open 2011 at 33,0 ft versus Tiara Yachts 3200 Open 2011 at 35,1 ft. Weight tells a clearer story for trailering families: the Tiara Yachts 3100 Open 2011 tips the scales at 13 225 lbs — 11 630 lbs more than the Tiara Yachts 3200 Open 2011 at 1 595 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 Tiara Yachts 3100 Open 2011 carries a rated maximum of 375 hp. Engine data for the Tiara Yachts 3200 Open 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Tiara Yachts 3200 Open 2011 carries 256 gallons versus 21 gallons in the Tiara Yachts 3100 Open 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 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.
