Got it. Instead of going in a curve / spiral, you go out a ways, circle away to maximal distance from the monster, then go out again. There's a distance where you can still circle the lake faster than the monster. That head start lets you win.

Turns out I told it correctly: https://puzzling.stackexchange.com/questions/2155/the-lake-monster

wasoxygen found it on StackExchange.

Psh, symbols. I spew the ideas and leave it to others to work out if they're actually sane.

Wow, okay, so I didn't even tell the question right but you still got the answer. The gist of it, I think, is that you can row 1 radius and the monster can run 4r and so you need to "shorten the circle" by rowing to r/4, whereupon you can move around the circle faster than the monster can run. I believe. That was roughly my solution (after I sugged 8bit's everlasting spiral) and my friend said I got it, but I may be mixing up the details. I'll try to get back to you with the actual question.
