Costarmoricaine : Erquy - Bréhat
You are viewing the standard program. This year, due to COVID-19, there are only 3 legs
Carte du Port-Clos

Date: On Wednesday
Distance: 28nm (52km)

For this first leg, the Formula 18 catamarans start in front of Erquy's harbor and finish at the Men Joliguet tower at Bréhat island, on the other side of Saint Brieuc bay. The distance between those two points is only about 20nm, but the catamarans, to comply with their navigation zone must stay close to the coast.


Warning:Provided geographical coordinates may contain errors, we disclaim any liability in this case. Furthermore, there are obstacles to navigation between some consecutive marks so you must prepare your navigation by carefully referring to a marine navigation chart.
