If my experience of cruising the northeast coast is of any value to you, allow me to recommend an air card. I, too, have to work from the boat, and without the air card, I would be unable to. I suppose a satellite
connection would be better, but I'm not willing to make that kind of an investment.
Based on my experience, if you're anchoring
, forget about being able to connect via wifi
. If you pick up a rented mooring
, very few marinas
that will reach out that far. In fact, I don't remember a single
one. I have found that even when I rent a slip (which I rarely do) at a marina which purports to provide wifi, more often than not, I'm just outside the useful range. That's true even at my home marina.
For what it's worth.
