When two boats share the same hull type — in this case both the Tiara Yachts 3900 Coronet 2013 and the Tiara Yachts 3900 Open 2013 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 Coronet 2013 at 41,9 ft versus Tiara Yachts 3900 Open 2013 at 41,9 ft. At 245 lbs and 245 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 power gap is worth calling out. Rated to 550 hp, the Tiara Yachts 3900 Open 2013 has a 70-hp advantage over the Tiara Yachts 3900 Coronet 2013's 480-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 535 gal and 535 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.
