Cozumel Mexico.. a four month divng interlude

We have good friends from Canada who moved to Cozumel Mexico in 1991 and opened a Scuba diving shop. Being scuba instructors we have been there many times. We promised our friends that we would spend our first Christmas and New Years aboard with them.We had an awesome time. It was a 50 hour sail from Havana Cuba to Cozumel Mexico. Check in took a few days of running around because we had to temporary import the boat since we were staying longer then 2 weeks. The TIP was $60 and good for ten years. Since we spent so long here it would be tough to tell you all we did suffice to say we visited many friends, did lots of dives, drank many margaritas and generally had a good time.
