Something I came across / old news, but new to me. Tampa, Florida to Yucatan, Mexico Ferry Service 2014 | Enjoy Cozumel's Blog Nierenberg expects to run two round trips weekly to Tampa, with a cost of $350 $195 (updated 1/31/12) for a round trip crossing in a cabin with meals included. We are still chugging ahead on the task of getting this new service up and running. We are still targeting the summer of 2014 for a start date. I am in the middle of the acquisition of ships for our various cruise/ferry services and one of them will be used in the service from Tampa Florida to the Yucatan.
Don't buy a used one from the cruise lines, it may breakdown, catch fire, run aground or have a virus. Seems to be the norm with them lately.
