Update June 26th 2021: max 4 persons or only same household. You can have a boat trip with whoever you want, as long as you maintain a mutual distance of 1.5 meter (5ft) between different households. This means, that when you’re not a household together, you have to maintain a mutual distance of 1.5 meter between friends, families, family and grandparents, two sets of partners, etc. This is quite possible on our spacious boats for 2 household with 2 persons or 4 households with 1 person.. Please mind that both police and municipal enforcers are keeping an eye on the canals, so please stick to the precautions to prevent high fines.
