What is the practicality of this tho?

I've sailed with a guy who had a Pactor modem + SSB radio + frequency thingy + one of the rigging cables made into 11 meter antenna.

Yes, it was cool AF from nerdy standpoint - calculate propagation and you can dial anywhere in the world. But also it's a huge investment. IIRC Inmarsat gives you all-you-can-eat (apparently the spectrum gets quite saturated in some areas quite saturated) matchbox sized modem that connects to your iPhone for $100 per month.

You'd have to sail for many years to break even and probably have worse experience all the time.

Until very recently, satellite broadband was unobtanium for most leisure sailors. It's much cheaper now, but $800 for an Iridium Go hotspot and $124/mo for service is still steep for leisure sailors who might occasionally need to send an email at sea. Any bluewater boat should have a decent HF rig for safety, so adding a Winlink system is basically free.
