Dfitchtx, the mid level really is a pretty good life. The satellite
communicator can be a life saver, and has gotten me out of a jam on shore (motorcycle breakdown outside cell phone range). We pay $12.50 a month for that. Our phones and tablets are hotspots, so that only means a cell phone contract
(Verizon in our case) that includes some data and the option to purchase
more when we need it. Thee are lots of isolated anchorages
that have cell phone coverage, and a cell phone booster antennas are available should we need one. It would be expensive to stream movies, but I prefer sunsets. Cell phone service tends to be strong where landline service was lacking prior to cell phones, because the infrastructure is so much cheaper.
I'm thinking of south Biscayne Bay, with Miami
lights largely over the horizon, and everywhere I can think of in the Bahamas
Best wishes to you on pursuit of your cruising dreams.
