The Tiara Yachts 3900 Open 2010 is the longer of the two at 41,9 feet overall. The Tiara Yachts 3100 Coronet 2013 comes in at 33,1 feet, making it roughly 8,8 ft shorter — a meaningful difference in deck room and overall on-water presence.

For trailering, the Tiara Yachts 3900 Open 2010 has the edge at 245 lbs dry weight versus 1 355 lbs for the Tiara Yachts 3100 Coronet 2013.

Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: What is the maximum horsepower rating for these boats?

The Tiara Yachts 3100 Coronet 2013 has a documented max rating of 375 hp. Engine specifications for the Tiara Yachts 3900 Open 2010 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: Which boat is wider, and does it affect trailering?

The Tiara Yachts 3900 Open 2010 measures 18" wide, compared to 15" for the Tiara Yachts 3100 Coronet 2013. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

The Tiara Yachts 3900 Open 2010 has the bigger tank at 535 gallons, versus 21 gallons on the Tiara Yachts 3100 Coronet 2013. That 514-gallon difference translates to roughly 1542–2570 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Tiara Yachts 3100 Coronet 2013 and Tiara Yachts 3900 Open 2010 from the same manufacturer?

Yes — both the Tiara Yachts 3100 Coronet 2013 and the Tiara Yachts 3900 Open 2010 are built by Tiara Yachts. That means shared dealer networks, common parts availability, and consistent build quality across the line.

Detailed Evaluation & Buyer Recommendation

Tiara Yachts 3100 Coronet 2013 vs Tiara Yachts 3900 Open 2010 — Same Brand, Different Boat

Matching a deep vee Tiara Yachts 3100 Coronet 2013 against a modified vee Tiara Yachts 3900 Open 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Tiara Yachts 3900 Open 2010 measures 41,9 feet overall (2010), giving it roughly 8,8 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 — 1 110 lbs more than the Tiara Yachts 3900 Open 2010 at 245 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 Coronet 2013 carries a rated maximum of 375 hp. Engine data for the Tiara Yachts 3900 Open 2010 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 3900 Open 2010 carries 535 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.

For family outings this is probably the sharpest distinction between the two. The Tiara Yachts 3900 Open 2010 is rated for 12 passengers, while the Tiara Yachts 3100 Coronet 2013 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tiara Yachts 3900 Open 2010 could be the deciding factor.

Bottom line: Choose the Tiara Yachts 3900 Open 2010 if your priority is putting more people on the water — it handles 12 passengers and at 41,9 ft it has the deck room to back that rating up comfortably. The Tiara Yachts 3100 Coronet 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
