I've never sailed in a cat, but I have a cutter
with a lot of mass and windage, and "back in ready to chuck lines" was the first thing I thought.
Have a crew on the ama closest to the neighbour ready to fend off, and of course, put out every fender
. I would rather have someone lurch gently into my hull
(I keep fender
out all around at dock) with four fat fenders out than to have them ram me at an angle while trying to solve their docking
issues with 2,500 RPMs of futile.
In fact, I make it a general rule
in neutral and I try to avoid even using reverse because I have a crew ready to take a line to a midship bollard on the dock
just to get me stopped. The rest can be done (usually) at some leisure.
By contrast, when being blown off strongly, I have backed out as fast as possible (I usually dock bow-in) and continued to back down the line in reverse, only swinging around when I'm in a channel free of boats. This is because the wind
will push the bow over faster than the rudder
I would suggest you practice first on a buoy in crosswind, and then on an empty wall, because windage will surprise you if you aren't used to it.
