Boating lessons

I dont undetstand, why this level is in the playable bug/exploit session. I solved it in two ways:
1. Without any exploits and very boring
2. with one or two long known and very common exploits....also quite boring.
Did I miss something???

Took me just a moment to realize how simple the solution really was. The level has a very attractive design and it looked as if the game play might be a little more complicated than it was. So was pretty to look at, easy and pretty quick to solve, and there were no nasty Zappers to worry about.
