$5000 a month? Who is this for? I'm a little confused. Seems like even the military would be reluctant at that price point, let alone private boat owners who aren't multimillionaires.
While I agree that the military would be unlikely to use this civilian service on warships, it's not because of the price where $5000 would be a rounding error in the operational cost of the ship.
I see this more for commercial operators, like the Ferry between Seattle and Victoria BC - they could sell high speed internet for $10/trip and make a profit if they can sell it to 500 passengers/month.
It's for those vessels already paying $5000+ a month for inferior service. I'm a coastal cruiser myself; obviously I will use the RV package on my boat.
