Why pickle yourself inside a glass-bound boat with fifty other people when you can cruise around on a smaller open boat? 
Those Dam Boat Guys offer the best of the lot. Though a young company, these Amsterdam-loving troopers originally from Canada and America have steadily climbed the charts on TripAdvisor, and recently claimed the number one spot under the boat tours and water sports category, beating out 47 other competitors in a matter of months. 
It's easy to see why. Knowledgeable, friendly guides with silent, electric boats. Plus you can bring your own food, drinks, and whatever you want to smoke (wink wink). Unlike the big boys, Those Dam Boat Guys are able to cruise you through the narrow canals effortlessly. 
Discover Amsterdam with Those Dam Boat Guys and be the envy of every bored passenger sitting around floating tables.
