H and I travelled north for a houseboating holiday on the Havel, which intersects with a few different national parks crossing the borders between Berlin, Brandenburg and Mecklenburg Vorpommern.
With our point of departure Röblinsee, leading to connections to the various lake districts (Seenplatten—including the Müritz where we visited years and years ago), we arrived at the harbor at midday and after orientation and a training module to operate the boat safely, it was too late to venture out before sunset and stayed in the dock in Fürstenberg overnight. 
The neighbourhood fronting the riverbank was lined with fancy villas and the industrial ruins of multipurpose food processing factory (Mischfutterwerk) was visible on the opposite shore. Three years prior to the Cuba Missile Crisis, the Soviet Union placed six armed launch for medium range R-5 Побе́да (Victory) nuclear warheads in early 1959–garrisoned troops left the small town in 1994. Behind the row of stately homes built originally for retirees from Berlin, a housing high rise for soldiers and their families stationed there. After an evening of planning and studying the channels and rotes, we were ready to head out.
