Everyone is assuming this caters to the rich yacht owner. While I'm sure that's a component of the target market, there are also plenty of other customers. Commercial fishing boats, coastal freighters, offshore oil platforms, cruise ships, various charter vessels, etc. It'd be worth it for a lot of businesses. And once it's available in the middle of the ocean, an enormous armada of freight vessels. $5k/mo is nothing for many of those commercial customers, both for improved logistics and metrics gathering and for keeping the employees/guests happy.
