The Tiara Yachts 3100 Open 2011 vs Tiara Yachts 34 LS 2023 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Tiara Yachts 3100 Open 2011 at 33,0 ft versus Tiara Yachts 34 LS 2023 at 34,9 ft. Weight tells a clearer story for trailering families: the Tiara Yachts 34 LS 2023 tips the scales at 13 800 lbs — 575 lbs less than the Tiara Yachts 3100 Open 2011 at 13 225 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 400 hp, the Tiara Yachts 34 LS 2023 has a 25-hp advantage over the Tiara Yachts 3100 Open 2011'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 3100 Open 2011 carries 21 gallons versus 2 gallons in the Tiara Yachts 34 LS 2023. 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.
