A mooring penndant can easily be sucked into the thruster.

I wondered about this. Are there not screens on the intake ports that would prevent this? If not, I agree this would be a good reason to not use it and even if there are, I can see where you still might not want to risk it. Hmm.

bowthrusters draw a lot of electric power, ... Not only does the motor heat up, but so do the batteries and cables producing and carrying that load.

This makes sense - thanks for pointing this out. Still feels like a bit of a design flaw to me...

I singlehand and use it for fine adjustments when approaching a mooring, as the rudder has no effect when I'm that slow. That allows me to easily pick up moorings alone without any stress.

Cool! At least this helps me not feel like a total idiot for thinking about this newbie

(I was waiting in the channel at the St. Martin drawbridge and a boat ahead of me had stopped and the boat behind me was too close, and the wind was blowing me towards the rocks) and it stopped working,

Yikes! That sounds terrifying. I guess you manage to keep her off the rocks!
