I saw more worse injuries from sailing on yachts than from cats. They have all sorts of things sticking up for you to trip on, slide into or fall on, especially winches and stanchions.

Saw a few big hits and lots of close calls with booms sweeping across during broaches,

crew picked up by the mainsheet and tossed across the deck

fingers/sensitive bits/clothing crushed in winches,

Had my hand 'smoke' when spinnaker halyard was let go as I was about to put it on a winch. Silly me froze just long enough to totally blister my fingers and palm. The only relief was holding a cold tinny for the rest of the race.

Scariest incident: Young guy working the bow nearly knocked out and sent overboard when he tripped the spinnaker shackle and it hit him in the temple. This on a yacht with no safety lines or stanchions.
