These Ports are all within 12 hours sail of Guernsey and are based on an average of 5.5 knots boat speed. The Author recommends that one purchases "The Almanach du Marin Breton (FF80) for those who can read French which contains all the French Tidal Ports to Biarritz as well as other very helpful information. (It is far less expensive than McMillans Almanach at £25 for CI boatowners).

For speeds greater than the above, please recalculate for your own vessel.
