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.

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

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