Hi, I'm also a non swimmer (well, I can kick around a little bit
) and I love snorkeling and am looking into diving (although I need the swimming skills to be on a little better level first). I'm pretty adventurous but I think the two things that helped me the most were: (1) being able to wade into the water instead of tumbling out of a boat. This allowed me to reach a comfort level with the water first. Being a non swimmer the thought of tumbling out of a boat right into the water was a little unnerving although I'm OK with it now. (2) There was a local guy along the beach that noticed, by my hesitant actions, that this was probably my first time snorkeling. He quickly jumped into the water and began swimming like a dolphin showing me that everything was OK. Little by little he and my hubby coaxed me into the water and before I knew it I looked up and was WAY out. I shrugged my shoulders and put my head back in the water. Having two really good swimmers on either side of me was a comfort. I knew that if I got into trouble they were there.
