Tiara Yachts 3900 Coronet 2013 vs Tiara Yachts 3900 Open 2009 — Same Brand, Different Boat

Matching a deep vee Tiara Yachts 3900 Coronet 2013 against a modified vee Tiara Yachts 3900 Open 2009 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.

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 2009 at 39,0 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 600 hp, the Tiara Yachts 3900 Open 2009 has a 120-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.

Bottom line: The Tiara Yachts 3900 Coronet 2013 at 41,9 ft is the right call if deck space, comfort, and entertaining are top of your list. The Tiara Yachts 3900 Open 2009 at 39,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Tiara Yachts 3900 Coronet 2013 vs Tiara Yachts 3900 Open 2009 — Common Questions

Which is the larger boat — the Tiara Yachts 3900 Coronet 2013 or the Tiara Yachts 3900 Open 2009?
The Tiara Yachts 3900 Coronet 2013 is the longer of the two at 41,9 feet overall. The Tiara Yachts 3900 Open 2009 comes in at 39,0 feet, making it roughly 2,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Tiara Yachts 3900 Coronet 2013 or the Tiara Yachts 3900 Open 2009?
For trailering, the Tiara Yachts 3900 Open 2009 has the edge at 245 lbs dry weight versus 245 lbs for the Tiara Yachts 3900 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.
Which boat can handle a bigger outboard?
The Tiara Yachts 3900 Open 2009 is rated to a maximum of 600 hp, giving it the larger power ceiling. The Tiara Yachts 3900 Coronet 2013 tops out at 480 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.
How many people can each boat hold?
The Tiara Yachts 3900 Coronet 2013 is Coast Guard rated for 12 passengers, while the Tiara Yachts 3900 Open 2009 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Tiara Yachts 3900 Coronet 2013 and Tiara Yachts 3900 Open 2009 share an 15 ft. (4.57 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Tiara Yachts 3900 Coronet 2013 and Tiara Yachts 3900 Open 2009?
Both boats carry similar fuel loads — 535 gallons and 535 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Tiara Yachts 3900 Coronet 2013 and Tiara Yachts 3900 Open 2009 from the same manufacturer?
Yes — both the Tiara Yachts 3900 Coronet 2013 and the Tiara Yachts 3900 Open 2009 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.
