Why not anchor
, the penalty for breaking the local law (Rule 7.0 Section 7.2(l)) states:
Anchoring in a location for longer than fourteen (14) days -- Twenty Five Dollars ($25.00) for the first day or part thereof after the fourteenth day in that location and Seventy Five Dollars ($75.00) for each subsequent day or part thereof.
There are plenty of places in Casco Bay to anchor
... make sure you change locations after 14 days. Call the Harbor Master in Portland
(207.772.2367) for the local interpretation.
I couldn't find the actual law limiting anchoring
to 14 days just the penalty.
