Tiara Yachts 3100 Coronet 2013 vs Tiara Yachts 3800 Open 2008 - Boat Spec Comparison

Q: Which is the larger boat — the Tiara Yachts 3100 Coronet 2013 or the Tiara Yachts 3800 Open 2008?

The Tiara Yachts 3800 Open 2008 is the longer of the two at 38,0 feet overall. The Tiara Yachts 3100 Coronet 2013 comes in at 33,1 feet, making it roughly 4,9 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Tiara Yachts 3100 Coronet 2013 or the Tiara Yachts 3800 Open 2008?

For trailering, the Tiara Yachts 3800 Open 2008 has the edge at 226 lbs dry weight versus 1 355 lbs for the Tiara Yachts 3100 Coronet 2013. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: Which boat can handle a bigger outboard?

The Tiara Yachts 3800 Open 2008 is rated to a maximum of 490 hp, giving it the larger power ceiling. The Tiara Yachts 3100 Coronet 2013 tops out at 375 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Tiara Yachts 3100 Coronet 2013 is Coast Guard rated for 10 passengers, while the Tiara Yachts 3800 Open 2008 is certified for 12. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

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

The Tiara Yachts 3800 Open 2008 measures 17" 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.

Q: Which boat has the larger fuel tank — the Tiara Yachts 3100 Coronet 2013 or the Tiara Yachts 3800 Open 2008?

The Tiara Yachts 3800 Open 2008 has the bigger tank at 411 gallons, versus 21 gallons on the Tiara Yachts 3100 Coronet 2013. That 390-gallon difference translates to roughly 1170–1950 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 3800 Open 2008 from the same manufacturer?

Yes — both the Tiara Yachts 3100 Coronet 2013 and the Tiara Yachts 3800 Open 2008 are built by Tiara Yachts. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Tiara Yachts 3100 Coronet 2013 vs Tiara Yachts 3800 Open 2008 — Same Brand, Different Boat

Matching a deep vee Tiara Yachts 3100 Coronet 2013 against a modified vee Tiara Yachts 3800 Open 2008 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 3800 Open 2008 measures 38,0 feet overall (2008), giving it roughly 4,9 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 — 1 129 lbs more than the Tiara Yachts 3800 Open 2008 at 226 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 490 hp, the Tiara Yachts 3800 Open 2008 has a 115-hp advantage over the Tiara Yachts 3100 Coronet 2013'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 3800 Open 2008 carries 411 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 3800 Open 2008 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 3800 Open 2008 could be the deciding factor.

Bottom line: Choose the Tiara Yachts 3800 Open 2008 if your priority is putting more people on the water — it handles 12 passengers and at 38,0 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.
