    Could you elaborate a little? What did you do to get your longitude? The latitude is relatively straight-forward, but any details you have might be of interest for folks not so familiar with all of this.

    Also you mentioned using "declination and equation of time from Eldridge's tide tables for year 2018 (the 4 year cycle for 2022)" which is certainly legitimate, but since most NavList readers don't have a copy of those tide tables handy, could you tell us what actual values you used? Thanks.
