Isn't 10Gbps for an entire ship kind of very slow?

It's not amazing. Assuming 3k people are using the connection simultaneously (I think these ships can have like 9k+ in practice), that is ~412.5kilobytes/second.

Probably not 3k simultaneously, not even close, but it only takes a few hundred people streaming 4K videos or downloading something for the whole network to slow down to a crawl.

The modern compression techniques can do wonders. See youtube for details. /s

I’m not sure 30% of people pay the $30 or whatever daily fee for wifi

that never happens tho. run a speedtest on a starlink airplane, nominally what like 400Mbps shared among 200+ passengers, and you'll get at least 40Mbps ish

A ship will likely have multiple uplinks, not to mention a lot of on board caching.

Pretty impressive. What is the laser link bandwidth between starlink satellites? Can any starlink node also be a relay station? I don't know much about the network, I guess I didn't really realize that links between satellites was a thing now, I thought it required that a node have LOS to you and a base station for the system to work.

(Edit) According to this (old) link there's something over 40pb of laser link traffic every day.
