So we played the session with the "boats" and "je skis". Went well until one player decided that rather than chase an NPC down a pier jumps on a jet ski. He flips a destiny for a large wave to come in and jumps it (two red, 3 purple difficulty) managing to clip the NPC and took him down. Safely jumps off but loses his weapon to the briny seas.
The jet ski then careened into a rack of parked vehicles for explosive fun causing the players to pay thousands in damages...
I love this game.
