motorboat

This motorboat fouled a wooden boat.

这只机撞了一只木。

The motorboat put on speed as soon as it left the pier.

一离开码头就加快了速度。

Powerboat racing began about the end of last century, and became truly international in 1922 with the organization of the Union for International Motorboating (UIM).

赛艇运始于上世纪末。1922年成立国际赛艇联盟，该运成为世界性运。
