PTE-RA讲解 Day70.The Cup Class boats 杯级艇
At the end of this year, we will launch the Cup Class boats. So these will be about twice the power. The sailors are down in cockpits, unlike today. A lot of the power is being generated by these four grinders that are providing hydraulic power, and that energy is being used to control the flying surface, the hydrofoil...and is also being used to control the wing and the flaps, effectively the engine, of what we have.
