Gen-5 Suspension System with Energy Recovery
roll, pitch and heave compensation in all operational scenarios whilst recovering energy from the waves instead of fighting the waves
Explored as an increased efficiency, weight-reduced alternative to Gen 4. Interconnected hydraulic system replaced with independent BLDC-motor-driven corner units interconnected electrically.
The Gen 5 Nauti-Craft suspension system is featured on the WB-24 / WB-27.
Each corner of the Gen 5 system has a passive gas spring for support working in parallel with an active circuit for damping and Deck Motion Control (DMC), packaged in a common cylinder.
The active circuit is comprised of a BLDC-motor-driven reversible pump assembly which discharges the battery during active control and charges the battery during damping.
Support hydraulics and motor controllers are mounted directly to the cylinders for high-response control with hydraulic and electrical lines connecting to batteries and manifolds housed in the hulls.
The ERS (Energy Recovery System) is a strong contributor to the hybrid propulsion system based on a 750 Volt DC PTI (Power Take-In).

Wallaby Boats GmbH
Your partner for high performance daughter crafts, CTV, pilot boats and small workboats
Wallaby Boats GmbH is the first OEM producing commercial boats using the Nauti-Craft suspension system on an exclusive right to the Nauti-Craft patent.
We are producing the prototype Wallaby-18 in Germany, bringing the technology from TRL 5 to TRL 7. For the WB-10 and the WB-12 Tuco Marine from Fåborg in Denmark is our preferred supplier for the production of the composite parts. We will build the boat, where our Clients want it built. We try to build as close as possible to their area of operation to reduce carbon overheads. You need Jones Act compliant boats - ask us.
Green Points:
- lowest fuel consumption per nautical mile
- first boat with energy recovery from waves during transit
- lowest carbon footprint per vessel lifetime
- blue angel design and operation
- EU Ship Recycling Regulation (EU SRR)

The Demonstrator "2 play" in Western Australia
In late 2015 Harald Hübner and Steffen Staudenmaier took a test ride on the "2 play" at Dunsborough in the south of Western Australia in rough seas around the Cape Naturaliste. The 8,5m boats' performance in 1,2m Hs waves at more than 25 knots was convincing.
