It is half past seven on a Saturday in late May. You back out of the slip with coffee in hand, twin V12s idling behind you, and the plan is simple: run forty miles north to the quiet cove, drop the terrace, and spend the afternoon in the water. By quarter past eight you are there.
That is the Tiara 39 LS working the way it was drawn to. It is not a center console with a cabin, and it is not a scaled-down express cruiser. It is a walkaround boat built around the idea that the run out and the afternoon at anchor are both part of the same day, and neither should be compromised for the other.
Who It's For
This boat makes sense for the owner who has outgrown a 30-foot runabout and has no interest in the operational weight of a 50-foot express. You want overnighting capability without the boat becoming about the accommodation. You want a real cruise range. And you want to run it yourself.
The 39 LS is also for the owner who spends the middle of the day at anchor rather than underway. If your boating is a long run followed by four hours in the water with people, the terrace and the convertible bow are what you are actually buying.
Design and Layout: The Terrace Changes the Day
Walkaround decks connect the social zones from bow to stern. Forward, wrap-around seating converts to a large sunpad. Aft, the cockpit takes either rotating lounge seating with storage or a module built around fishing. That choice is made at order and it changes what the back third of the boat is for.
The portside terrace is the feature that reorganizes everything else. It folds out to widen the cockpit at anchor, putting a platform at water level off the side of the boat rather than only off the stern. A starboard boarding door handles people getting on and off. Together those two details are why guests end up using the boat rather than swimming beside it.
Below deck the 39 LS carries a forward queen berth, a private head, and a mid cabin storage area that converts to a berth. That is enough to host guests overnight, or to give someone a quiet place to lie down mid-passage, without the boat needing to be a cruiser to justify itself.
Performance: The Cruise Band Is the Story
Twin Mercury 600 Verado V12 outboards drive the 39 LS, with joystick piloting and integrated Garmin navigation.
Tiara tested this hull on Lake Michigan off Holland at 26,632 lbs as tested, two aboard, in under a foot of sea. Wide open throttle was 54.0 mph at 6,146 rpm; idle to 30 mph took 11.5 seconds.
The two published optimum cruise settings are where the boat earns its keep. At 4,500 rpm it runs 35.5 mph for 312 statute miles. At 5,000 rpm it runs 42.4 mph for 330 - which works out to 286 nautical miles. Both come off 90 percent of the 500-gallon tank.
Read that twice, because it is unusual: the faster of the two settings is also the longer-legged one. On this hull you are not paying range for speed inside the cruise band, which makes 5,000 rpm the number to plan a crossing around.
The 21-degree deadrise at the transom is what carries that speed when the water is not flat, and at 21,339 lbs dry the boat has enough mass to stay composed rather than busy.
What to Check at Sea Trial
Decide the aft module first. The rotating lounge with storage if the cockpit has to seat people, the adventure module if it has to fish. Reconfiguring later is a refit, not an afternoon.
Deploy the terrace at anchor while you are aboard, and put someone in the water to board from it. That is the feature you are paying for; test it rather than reading about it.
Then run at your intended cruise rpm and get observed burn in writing. Tiara's published figures describe one hull on one day at one weight - work your own numbers off 500 gallons.
Where to Start
The 39 LS sits in the middle of Tiara's Luxury Sport line, between the 35 LS and the 43 LS, and it is where the line picks up the portside terrace.
It shares its 39'6" length, 12'6" beam and 21-degree deadrise with the 39 LE, and the two split on where the volume goes. The LS keeps it on deck - walkaround access, the terrace, a convertible bow - with a queen berth and a convertible mid cabin below. The LE puts it below, in two sleeping quarters and a galley. Drive both on the same day; the choice is about where you want the space.
