Reminds me of an off the beach Fort Lauderdale Laser regatta in 1974 where a Portuguese Man O" War washed into a competitor's cockpit and stung him all over the legs ..... well didn't mean to ruin this nice photo image .........
Ok, now I feel even more fat & out of shape. . . ;-) But nice photos (they have two posted on line here) it really shows how fit the top sailors in the class have to be.
