Offshore Navigation Tip

When preparing for a coastal passage go onto Google Earth to check the Longitude and Latitude of each point, harbour, etc along the route and measure the distance between them.

Then set up a table with columns for point or harbour etc Waypoint, Longitude, Latitude, distance, time in hours at 6 - 7 - 8 knots.

Print out the table and put it in a plastic sleeve at the nav station so all the crew can check how far, how long and waypoints at any time with minimum mental exertion.
