The Digimap Marinas was first set up to help fellow boaters when they first visit a marina.
For mobile phones, the links to the marinas pages are at the bottom of this page. There are separate sections for Southern Brittany and Normandy.
Videos have been added for many marinas to help you see what to expect. Charts, as important as they are, can only show so much.
More recently, the site has provided valuable information on the Douane requirements post Brexit, to help boaters navigate the paperwork and rules for entering and leaving France and the Schengen area.
