Interesting to note that when he stopped to pump out -- the harbormaster in Tashmoo offered me a pamphlet this year with visitor info. See link below.
Note that they prohibit generators except between 9a to 9p, you can't leave a transient boat anchored unattended for more than 24 hours, and transients can't stay anchored more than 3 days.
I think it would be better if they limited generators to 9-6, but that's just my opinion.
