Nauti-Craft™ Marine Suspension Technology. A radical departure from naval architecture principles. Nauti-Craft Pty Ltd is a research and development company focused on the design and development of the Nauti-Craft™ marine suspension system. This patented technology separates the vessel's hulls from the deck and superstructure via a 'passive reactive' interlinked hydraulic system which provides increased levels of ride comfort, control and stability whether stationary or travelling at speed.

The Nauti-Craft technology is a hydraulic suspension system for multihulled vessels. The system separates the hulls from the superstructure which allows the hulls to react rapidly to wave inputs and conform to the ocean surface without transmitting high forces and accelerations of the hulls to the deck and superstructure. This provides increased levels of ride comfort, control and stability whether stationary or travelling at speed. The improvements to stability and maintaining a level attitude can be further enhanced with active control of the suspension system. This has great potential applications for commercial, military and recreational vessels.


The need for marine suspension.

• Reduced slamming and jarring motions

Improves comfort and safety.


• Reduced roll and pitch motions.

Reduces sea sickness.


• Improved planing speed in rougher conditions

Improves speed comfort and efficiency.


• Cost Versus Performance

Allows a smaller vessel to provide seakeeping typically only found in larger vessels while having the lower operating costs of a smaller vessel.

Innovative Features

• Passive Reactive System.

Hydraulic interconnections provide beneficial functionality without requiring power when underway or at rest.
• The elegant and devious combination of interconnections provides a PASSIVE mode decoupled solution for optimal tuning for comfort and safety

• Mode decoupled roll, heave, pitch and warp.

Allows the hulls to individually conform to the ocean surface or accommodate wave inputs while maintaining the stability of the body (deck and superstructure).
Permits the hulls to move rapidly with high accelerations while reducing the acceleration levels on the body.
Reduces load inputs to the body and reduces the torsional loading on the body.
Permits simplified active control of roll and/or pitch attitude at (low) body frequencies while allowing the passive reactive system functionality to react to and distribute loads from (higher) hull frequency inputs.


• Auto adjustable for different load conditions and sea states.

Self-levelling of the body with adjustable height.
Electronically auto adjustable controlled variable damping.


• Optional active roll control for fast efficient and stable cornering.
• Optional active pitch control.
• Optional DACS (active ‘skyhook’ Deck Attitude Control System)
• Uses standard marine, aeronautical, agricultural & automotive types of components.
