When two boats share the same hull type — in this case both the Tiara Yachts 3900 Convertible 2010 and the Tiara Yachts 3900 Convertible 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 3900 Convertible 2010 at 41,6 ft versus Tiara Yachts 3900 Convertible 2011 at 41,6 ft. At 30 125 lbs and 30 125 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The Tiara Yachts 3900 Convertible 2011 tops out at 550 hp. Engine specs for the Tiara Yachts 3900 Convertible 2010 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 475 gal and 475 gal — so range won't be a tiebreaker here.

Both boats are rated for 12 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.
