Up here in Maine, at least, we are blessed with all these fixed
reference points and current direction and rough velocity indicators,
known by the quaint local term as "Lobster Pots".

Pick a slack current time and set up a waypoint to distant
landmark.

Little or no wind is also very desirable, especially for a high
profile boat. Trying to determine if the current is really slack on
a
windy day is next to impossible.

What am I missing here? You need to be able to see your compass
heading when
pointed directly at the waypoint, and the GPS reading at the same
time.
Seems to me it would take an awful lot of wind or current to prevent
you
from doing that.
