I don't know since when but for some years now you have to sail away from the Island after the lighthouse and end of the island to what is called the VC bouy and than turn right towards the south west and the Island again. This little triangle is about 9 nm and in the earlier time you were allowed to hug the bay side of the Island . The Nothern part of this old route is now a small nature reserve (Vlakte van Kerken)
