Did this summers when I was little on my dad's sailboat De Swarte Bere (black bear) in the Netherlands. Fond memories of Willemstad, Helivootslaus, Dordrecht (where the shipbuilder lived and I fed the ducks.) Most memorable sail was through the canals to Belgium followed by the North Sea where the waves seemed 20 feet high (might've been 10 feet, but I was little).
