And yet another Starlink option. I received this back in October. This it is basically their RV program using the full-size residential unit.
I tried the RV unit, but service was spotty. You need an unobstructed view to north and we have too many trees on our property.
Should not be a problem on a boat!

"Starlink
Your service area remains at capacity which means we are unable to convert you to Residential service at this time. Our best estimate for delivery of Residential service in your area is now mid-2023.

Adding users before adding additional network capacity would result in delivery of a lesser service. However, we understand that some customers may have urgent connectivity needs with no other alternatives.

For those with urgent connectivity needs, we are offering a Best Effort service option.

What is Best Effort?
Best Effort enables typical internet activity with the understanding that Best Effort users will be deprioritized behind Residential users.

The monthly service charge is the same but unlike Residential, Best Effort users will have the option to pause service on their account page."
