Meine Englische Sprache ist viel besser als meine Deutsche Sprache. That is why I write in English. Sorry for that.
I finished a sailing guide for the IJsselmeer, Markermeer and the Randmeren, I am thinking of a translation in German. It is a book with tips and tricks and a lot of history of all islands, towns and harbors at the former Zuiderzee.
I made some clips about sailing in the Netherlands. I am always happy to see German sailors, they know their thing.
