PS got my hands on a light list .....no tidal info in there for

The height of the light is from MHW on US charts. That is about all
the tidal information in that publication.

If you use the "dipping the horizon" technique for establishing a
circle of position, the height of the tide at the time of the
observation must be taken into consideration.
