What kind of boat
do you have?
The best deal right now for light web browsing, FTP, etc without breaking the bank is an Inmarsat Fleet One. It's about $3K for the hardware
and then a service
plan. They have a special Americas Leisure Unlimited plan that works up to 200nm off the coast for North/Central/South America. Speed is only 100kbps but still fast enough for light web browsing, etc. In a given month, the plan provides 30MB of data at 100kbps, followed by an additional 30MB of data at 32kbps, then unlimited at 16kbps. At the end of each month, the speed resets. https://www.sea-tech.com/product/fle...irtime-bundle/
Depending on how much data you think you need, this may or may not work
. I know of a boater who uploaded videos to Facebook with this same plan, it took a while, but it worked.
After that, you would be looking at Iridium
Certus, which will be more like $7K for hardware
, and a few hundred $ per month, but higher speeds (750kbps to 1.5mbps). Certus isn't quite available yet but will be in a month or so.
Finally, there is KVH which is much faster and the data (per-MB) is much less expensive, but the hardware cost is much higher. https://www.sea-tech.com/product/kvh-tracphone-v3hts/
