I haven't had much chance to take it out yet, but a few times on a local lake. I have to agree that with me alone, the wind does make it hard to handle with a paddle, but I bought a 54lb electric motor and with the battery up front for ballast, it handles beautifully and zips right along. I haven't done much colliding with underwater objects, but having read the comments, I'll be careful.
