Timbo most of my sailing exp has been on larger keel boats. Pac seacraft 37 and a Hunter 40 these were OPBs. I have some experience on smaller boats but that was close to 15 years ago. Most recent thing that *might* be comparable to this is track days on my 675. Weight shift is key on a bike for loading/unloading the front end and proper turn in on corners. I would expect it to be similarly important on a cat that might only weigh 16kg more than I do.
