SeaDek’s Closed-cell Foam Helps Quiet Sea Ray SLX Models


A closer look at the exclusive Quiet Ride technology that reduces noise, vibration and harshness (NVH) up to 50 percent on a Sea Ray.

Maximum performance requires sacrificing the comfort of the ride, because an engine at full throttle generates significant sound and vibration energy.

THE METHOD: Engineers measured 48 points on Sea Ray sport boats at idle and full cruising speed to isolate the sources of decibels, vibration energy and harshness. In-depth vibration analysis showed how to dampen and interrupt vibration flow at the source.

INTERPRETING THE DATA: Performance and a comfortable ride aren’t mutually exclusive if you can reduce vibration energy at the source. To accomplish this, engineers started from the literal drawing board, redesigning new Sea Rays with integrated Quiet Ride technology.


Exclusive to Sea Ray SLX models, Quiet Ride uses a multi-pronged approach to dampen NVH at its root sources.

FIT AND FINISH: Closed-cell foam knocks down NVH. Neoprene isolators and mounting brackets reduce vibration. Heavy-duty magnets, latches, bumpers and gaskets ensure silence from hatches. Wind-struck edges are fared to let the wind slip by silently.

ENERGY-DISSIPATING HULL LAMINATE: Sea Ray’s specially engineered hull laminates convert vibration and noise energy into heat energy, which water whisks away.

FULL-BEAM BULKHEADS: Full-beam bulkheads and full-stop blocks in the boat’s cavities trap and isolate energy, preventing sound from traveling and surfacing elsewhere on the boat.

A well-buffered hull offers acoustical insulation, while structurally bonded hulls, liners and decks reduce vibration.

TUNED TRANSOM®: Borrowing vibration-abating technology from space shuttles and jet engines, the Tuned Transom from Omni Products short-circuits energy at the source to dampen excessive noise.
