I very much enjoy sailing at night, and there are certainly additional risks.
Most charter places here (PacificNW USA) disallow sailing at night.
Anyway - we have crab pots not lobster pots, same risk though.
For my night time sailing, I like to be out in the channels and away from shallow waters where pots might be snagged.
Another thing matter, at least here, is understanding how the local currents run. Not just for a speedier passage, but at night to avoid deadheads and things like that.
All in all, thinking about stuff wrapped on the prop or shaft after a long sail (day or night), is a good reminder to get the engine spun up, in forward and in reverse, well in advance of when you intend to be needing to use it?
