It is half past seven on a Friday morning and you are already thinking about the weekend. The calendar is clear from Saturday noon through Sunday sunset. The kids want to bring friends. Your spouse wants to anchor somewhere quiet. You want to run. Nobody has to be hired for any of it.
That is the Tiara EX 54, and the reason it works is arithmetic rather than atmosphere: three private cabins and two heads on a 54'3" hull that a competent owner and one other person can dock. At this length that combination is unusual, and it is the whole argument.
Who It's For
The EX 54 fits the owner who is done with crew. Joystick docking, an aft-facing camera on the glass cockpit and assisted docking are all standard on the theory that you and one other person put the boat away. If leaving on a Friday afternoon without coordinating anyone else's calendar is the point of owning a boat, this one is built around exactly that.
It fits a family of six who want three separate cabins. Three staterooms and two heads at 54 feet is a genuine three-cabin arrangement, not a bunk alcove counted generously, and it is the reason to look here rather than at a two-cabin boat of the same length.
It does not fit a buyer whose first question is top speed. Wide open throttle is 38.7 mph, and the boat is happiest at 26 to 30. And it does not fit anyone who wants an upper station - the EX 54 is a single-helm boat under a hardtop.
Design and Layout: A Cockpit You Order
The aft cockpit is a decision you make at order rather than a fixed layout. Tiara builds the EX 54 with three module selections - a social configuration, an adventure configuration and a glass patio - so the back of the boat is set up around what you actually do out there.
The glass patio changes the character of the interior more than its name suggests. Ordered in place of the social or adventure cockpit, it extends the finished, glazed living space aft instead of leaving the stern as open deck. It is the version to look at if your boating is long lunches at anchor in changeable weather rather than fishing or water sports.
Twin terraces open the cockpit outboard to the water on both sides, and the swim platform carries integrated steps, which makes the whole stern the swimming and tender end of the boat. Forward, the bow is easy to walk to and gives you a second exterior lounge away from the cockpit crowd.
Inside, the salon and galley share the main deck on one level, drawn for dining and entertaining rather than for a cook working alone out of sight. Sight lines run forward to the helm, which is the part that matters when you are the one driving - the person at the wheel stays in the room.
Below deck, three staterooms sleeping six adults, with two heads. The cabins are separated for privacy. Tiara's virtual tour is the quickest way to read materials, finishes and how the below-deck spaces divide before you travel to see a hull.
Performance: The Sheet Tiara Publishes
Tiara tests its boats and publishes the sheet, which at this length is rarer than it should be.
The EX 54 on twin IPS2-950s was run at Stuart, Florida on 23 January 2024 with fuel, water and waste tanks all full, three people aboard and a weight as tested of 56,891 lbs. Wide open throttle is 38.7 mph at 2,561 rpm, burning 74.2 gallons per hour. Idle to 30 mph takes 15.5 seconds.
The band to plan around is the optimum cruise: 26.0 mph at 2,000 rpm on 44.3 gph, or 30.6 mph at 2,200 rpm on 53.7 gph. Tiara's own arithmetic, worked on 90 percent of the 650-gallon tank, puts that at 299 nautical miles at the lower setting and 290 at the higher.
Four and a half extra miles an hour costs nine nautical miles of range. That is a flat enough trade that there is no real penalty for running this boat at the top of its cruise band, which is not something you can say about most hulls.
Noise at the helm is 71 dB(A) at 2,000 rpm and 72 at wide open throttle. One decibel separates loafing from pushing.
Deadrise at the transom is 14 degrees. That is a cruising number, and it is the correct one for a hull built to hold a flat, dry attitude in the high twenties rather than to punch a head sea at forty.
What to Settle at Sea Trial
Propulsion is pods, so slow-speed work happens on a joystick with the aft camera up on the glass cockpit. Dock it in a crosswind, in a slip the width of the one you keep, before you form an opinion about handling from the way it feels at cruise.
Choose the cockpit module against how you actually use a cockpit - social if you entertain, adventure if you fish or run water toys, the glass patio if you want glazed living space aft.
And if you are planning a season around fuel, plan it off the published sheet: 44.3 gph at 26.0 mph, 53.7 at 30.6, worked against 650 gallons. Then get observed burn at your intended rpm in writing on the day.
Where to Start
The EX 54's first competitor is the boat on the next stand. The 56 LS is two feet longer and answers the same length question from the opposite direction: four outboards, 54.4 mph, 1,000 gallons and two staterooms, against the EX 54's twin diesel pods, 38.7 mph, 650 gallons and three. Outboards or inboards, speed or cabins. Tiara has split the choice cleanly and expects you to pick a side.
Where the EX 54 argues is documentation and configurability. A published test sheet with rpm, gph, decibels and calculated range at every step is a rare thing at this length, and a cockpit ordered in one of three configurations means the boat you take delivery of is the one you use.
