Why a torpedo?
Because when properly submerged it has much lower drag resistance and lower wake generation if compared with traditional hulls.
This is meaning LESS Energy Consumption, higher environment sustainability.
At all speeds!
Low drag resistance
Be efficient,to really be green!
The torpedo requires much less energy and, thanks to its tapered shape, is characterised by reduced hydrodynamic resistance.
A conventional hull, on the other hand, must plough through the water and support the body of the boat, and this results in a great deal of drag.
The torpedo is by itself efficient like the hydrofoils we’re using as its appendages. They are used both to raise the boat and to stabilize in pitch and roll the boat underway.
This is massively increasing the confort onboard, even at low speeds, when other foilers are just operating in displacement, not efficient mode.
Flying at low speed
The combination of foils and torpedo, allows in-flight navigation even at low speed.
Thus Gerrisboats is gentle, producing little wave, both when starting on the side hulls and when in the air.
