Dinghy sailing and hip replacements

I am 10 months post full replacement, had a couple of “ subluxation “ events ( partial dislocation of joint ) which put me back a bit. I have gone back to Pilates which has helped enormously as the instructor has tailored some of the exercises to improve my hip, cycling and walking is also good . My experience is that rotation exercises / movement of the hip takes longer to sort than the basic walking / cycling exercise where everything stays in line.  My concern is impact damage, I normally sail a Fireball and am worried about impact damage should I lose grip / get washed off of the gunwhale. It is not always easy to control the “ landing “after you have become the dope on the rope ! Going to give it a go in 2020 , light stuff first gradually building up.
