This library gets you both the sounds of a tugboat / motor engine boat, as well as a sailboat.
It delivers powerful boat engine sounds such as accelerations, stopping and idle sounds. You also get radio VHF chatter, cabin roomtone, splashing waves, the sounds of anchors being dropped and handled and mainsail hoisting sounds. There's also lots of ropes creaking and squeaking, winches, furlers, genoas flapping and raising, sailboat interiors with light swells. Finally, it includes some quiet ambiences from a big city marina.
So if your project calls for boat sounds, there's lots to work with here:
