Why Marine Suspension


In a high-speed boat, travelling in rough water can be torture.

The continuous slamming actions as the vessel’s hull impacts the next bit of chop or wave can wear you down. Worse still, rough waters and chop can cause serious injury.

The only alternative is to slow down dramatically, which makes the ride better, but much longer. 

In a Nauti-Craft equipped vessel, every bit of chop of wave can be soaked up by 700mm of suspension travel. This is equivalent to the suspension available in a monster truck and more than 3 times the travel available in a suspension seat.

That much travel reduces the effect of slamming impacts by around 80%, which means a injury generating 7.5G impact, becomes a slight 1.5G impact, and it also makes flying over chop a lot of fun.

Anyone who has ever tried to step off a boat onto a jetty on a bumpy day knows that things can go very wrong very quickly.

That slightly bigger wave comes through and suddenly the bow of the boat lifts and drops just as you were getting ready to make the step. It is a lot worse if you are halfway through that step.

The world disappears from under your feet and the best outcome is to fall in the water clear of hitting something or being hit by the boat. 

Vessels up to 30% smaller can now provide the same transfer performance at a fraction of the capital and operating costs, with Nauti-Craft Marine Suspension Technology.

Improved vessel comfort, safety and performance with Nauti-Craft

Nauti-Craft suspension systems
eliminate commercial boating risks

By pushing the bow of the boat against the object you want to step onto, the suspension system becomes able to soak up the waves as they pass through.

The hulls move up and down, the bow stays fixed to the object and you are safe to step across. This concept of push on transfer is commonplace in the offshore wind industry, but without the suspension system, the risks are much greater.

With normal vessels the bow can slip when a big wave or trough comes through. These are only called slips when the bow slides more than 300mm (1ft), but it is not unheard of for these slips to be up to 2m, and when they slip, it can get very dangerous.

With windfarm vessels equipped with suspension travel of up to 25% of their beam, an 18m vessel can feature 2m of travel, enabling it to offer safe transfers in seas more than 2x the current range of vessels.

Nauti-Craft provides solutions to the wind farm industry.

Loitering Stability

The rolling and pitching of a commercial vessel can be dangerous and leave you seasick.

However, with our innovative boating technology, all you need to do is switch on “Nauti-Craft’s proprietary Deck Active Control System” and the vessel’s rolling and pitching becomes almost unnoticeable.

By hydraulically shifting fluid between the cylinders, the active control system can counteract the rolling and pitching motions induced by the waves. Using an accelerometer mounted on the vessel deck, the control system measures the deck roll and pitch angles and maintains them within 3 degrees of horizontal.

This function is limited by the amount of suspension travel available, but even once travel limits are exceeded, the roll and pitch angles are greatly reduced compared to a normal vessel.

Nauti-Craft provides stability and therefore safer boating conditions.
