This is Coco's 2nd Jet Ski level. It's longer and a bit more difficult than Makin' Waves. Now there are Great White Sharks that could eat her, and pirates that could hit her with their anchors.
All you can do is dodge all of those obstacles and everything else I didn't mention.
There's a bit of a branch halfway through the level that you must make sure to go through if you want to get all of the crates. The very first time I played through this game years ago, I didn't know about that at all.
