SU Marine Launch Trio of New Tenders

By Paul Joseph

Turkish boatbuilder SU Marine has carved out an impressive reputation down the years, not just for its luxury sailing and motor yachts, but also its innovative tenders.

Now the Istanbul-based company has unveiled a brand new trio of tenders, each boasting an array of innovative design features that make them ideal support vessels for superyachts.

Marketed under the Reliant brand as part of its long-standing joint venture agreement with SU Marine, the tenders are all distinctive in their own way.

First up, the X40L Lander is a 40-foot utility boat designed so that it can serve as a working craft in the morning and a luxury SUV in the afternoon.

Perhaps the vessel’s most eye-catching and unique feature is its 4 hydraulically actuated platforms - one on each side - that turns it into a party boat including a table that can seat 14 and rises out of the deck.

Furthermore, carbon-fibre “wing” doors fold down to expand the party space, and on bright sunny days, an overhead canopy can be rigged. A powerful entertainment system with Apple Airplay plays music and movies, and dramatic footlighting and underwater lights help set the mood. 

In light winds and calm seas, with two crew aboard and carrying no extra weight or ballast, the X40L cruises at 11 to 16 knots and can hit 24.1 kts. Unballasted but with a vehicle on board, the boat cruised at 10 to 12 knots and has a top speed of 16.4.

The X40 Express, meanwhile, is billed by its designers as a modern, robust, and luxurious interpretation of the classic express design, with its plumb bow and straight, clean lines, accentuated by a cambered teak deck.

Framing that deck is an eye-catching, uninterrupted, low-profile cap rail painted the same metallic silver as the hull. But perhaps most striking is when the carbon-fiber hardtop is removed, turning a coupe into a convertible.

Initial sea trials near Istanbul in light winds and calm seas indicate that the X40 could run at 40 knots, topping out at 40.7 knots at 3300 rpm.

Completing the trio is the X40T Limousine, which has the same clean lines and powerful hull shape as its sistership, the X40 Express, and boasts an expanse of teak deck, and metallic silver paint jobs accented in black.

The X40T cuts a profile much like the Express with a nearly plumb bow and subtly reversed transom over complementary stern platform. In the “cab” or main saloon, there is full standing headroom with excellent views all around, whether standing and sitting.

Passengers can access convenient wifi routers and use Apple Airplay to engage a powerful stereo system from their smartphones.

The aft end of the saloon features a full head compartment to port and a galley and bar to starboard, plus a door to the open-air aft cockpit. Above, the cockpit can be covered by a powered awning for sun protection.

Early sea trials saw the vessel’s twin Cummins QSB 6.7 425HOI diesels and Konrad 660b Stern Drives take the boat up to 38 knots, with a cruising speed of 26.2 knots at 2400 RPM.

SU Marine was founded in Istanbul in 2007.
