Patented hull technology
for a better ride


Petestep® deflectors lower slamming in rough seas and reduce G-force by up to 50%, with unmatched ride comfort as a result

Softer ride


No more clatter and clinking from the hull! Petestep® hulls create a lot less noise from the sea, therefore significantly adding to the comfort of the ride

Quieter ride

Lower consumption

Up to 35% less energy is required to propel the boat forward, in effect lowering fuel consumption and increasing range

Lower consumption

More stable

Stability is increased both at high speed and at the dock, making you feel safer on the water

More stable

“I’ve never felt anything like it – it really is amazing!”

– Jack Haines, Motorboat and Yachting (UK)

The Petestep® spray deflectors

Our patented technology with the unique combination of significantly higher comfort combined with the best planing efficiency in the industry. You can’t get a better ride!

How does it work?

Spray water makes a difference

Our patented technology utilizes the otherwise wasted spray water, and creates a significant increase in efficiency and comfort

Conventional hull technology

Conventional spray rails

Spray rails are noisy and make the boat slam harder in waves. By pushing spray water to the sides of the boat, spray rails also waste hydrodynamic energy, resulting in a significantly higher fuel consumption than necessary.

Petestep hull with deflectors means a softer ride

Petestep® deflectors

Petestep deflectors redirect the otherwise wasted spray water down and aft, consequently providing a lift and forward thrust force on the boat. The combined result is a much lower energy need than other V-bottom hulls.

How can we help

Hull development

For all boat models, we design the Petestep® hull to suit this particular model’s intended use and characteristics, along with its specific engine options. This ensures that the boat will always run with great comfort combined with maximum efficiency.

Performance estimates

Most projects start in a feasibility stage, where Petestep supplies predictions of the performance and powering requirements. This also occasionally includes a comparison to a conventional hull, in order to illustrate the performance differences

Advanced analysis

We can handle most advanced analyses on planing hulls, including turning and wave simulations. Also how propulsion systems such as water jet and surface drives affect the performance and seakeeping.
