nb Innisfree

With Innisfree prop walk wasn't very noticeable when in reverse unless near piling when it seemed to go in the opposite direction most of the time, I eventually came to the conclusion that the prop helix when in reverse would bounce back off the piling and hit the swim and push it away...but sometimes it could go either way or neither, it seemed to depend on water depth and shape of canal bed near the pilings. I could never reliably guess which way it would go, so just adjusted to behaviour at each occasion. Very complex. ETA: It also depended on which side the piling was on, if on the stb side prop walk would often be conventional, but then again depth of water and canal bed blurred the results. Witchcraft
