Precepts on the Peat Course

The Peat Course provides all persons on board with freedom and peace. Please bear this in mind, especially towards your fellow visitors and other persons concerned. Keep your pets on a leash and prevent nuisance caused by noise.

Generally you can remain with you boat somewhere for a longer time, unless there is an indication at that particular place that says otherwise. At the moorings at Appelscha, Donkerbroek, Hemrik and Wijnjewoude, long-lasting mooring is only permitted, when the boat is staffed during the evening and at night. Unmanned, this period is 3 days. This rule of course does not apply in case of local harbour dues.

It happens sometimes that you will have to wait longer for a lock or bridge than you would like. Usually the lock and bridge keepers are watchful to your arrival, but sometimes they got caught up as well. Please keep your patience in that case, eventually you are on holiday. Should you find that there is no obvious reason to explain why the delay is longer, please call one of the board members of the foundation The Nije Kompanjons or the province, 058-2925888.

We do the best we can to make your visit to the Peat Course as pleasant as possible.
