Before we came down to SP last month I bought some short fins. I was conserned about my long fins damaging the coral The current at Mexico rocks was strong enough that day I had to change and put the long ones on. But I was very careful to stay far enough away as not to touch the coral. Two or three days later we were at Hol Chan and I could use the short fins with no problem.

I'm not a strong swimmer hence the long fins. But I float with the best of them. LOL
