snorkel/SUP question

SUP sounds better the more I hear about it! Are the "rocks (links)" you refer to across the bay from La Ropa around that little peninsula serviced by Paseo del Morro? Are there any dangers we should be aware of in Zihua Bay: rocks close to surface, unfriendly fish, currents? Despite all these questions, we're not timid about trying SUP and I'm sure we will do fine---just need to keep our balance! Isn't the worst that could happen is that we'll fall off into beautiful 80 degree water?
Thanks again for all the great tips!
