Right, but that is cost I could potentially swallow; worth it work from paradise anchorages with little other connectivity. You don't pay rent at anchor.
What I will probably end up doing this summer is a stern-to mooring to some trees with a Starlink terminal sitting on the beach with an Ethernet cable running out to the boat.
What about point to point WiFi instead of a cable?
WiFi 6 will handle anything that Starlink can possibly hand out.
With a directional antenna, you'll have more range than you would ever want to store cable for.
Then again, I would think you could make a stabilized platform that could keep a starlink connection up.
The advantage of Starlink over point to point WIFI is there is so much less set-up involved; just update your service address and boot your terminal and you're good to go. Conveniently the ethernet cable will also power the terminal from the boat's batteries.
If you're that close to the beach that you can string a cable, do you not have 4G LTE/5G services available? With a high-gain antenna I would imagine you could get speeds and latency that would rival Starlink in many places. Of course, this will vary wildly and depends on how remote you are mooring.
It just depends; every anchorage is different however it's not uncommon to be cruising in area with great coverage, but once you lay anchor you find yourself without service because the rocks of the bay you chose to shelter you from sea waves also shelter you from radio waves.
It doesn't deal too well with all the movement; it works sometimes but not reliably. I don't know if it is only the rolling or also the lateral swinging around the anchor that throws it off.
In perfectly flat seas it might work fine, but you don't often find yourself in those conditions.
Catamarans tend the roll pretty aggressively, even if they aren't going to roll over a wide angle.
A SWATH - small water-plane area twin hull - would be a better choice.
Basically two completely submerged pontoons with small pylons passing though the water surface up to the superstructure.
Because they have very little boyancy change when the waves change the water surface level, they have very gentle roll characteristics.
