edbulmer, There are many beautiful choices for your Keys cruising. Although, as said above, the
ICW is not passable south of Marathon, the Big Spanish Channel may be available with your
draft for running on the Gulf side and into
Key West via the NW Channel. Also, keep in mind that those referrences to Hawk's Channel arte not "offshore". The outer
reefs keep Hawk's Channel relatively calm. If your
draft is less than five feet there are many pleasant and protected
anchorages on the bayside. If you use Hawks Channel you can find good
anchorages at Rodriquez Key (except NE) , Tavernier, Channel Five (under the fixed bridge), Moser Channel and Newfound Harbor.
