Not much to it, but we saw it on the canal tour. Apparently, many boats are too tall to traverse the canals without a bridge lift. Also interesting fun fact-living on the canals is super pricey because there is a limit to the number of houseboats on the canals. Apparently, there was a housing shortage post-WW2. But, the houseboats gradually because really really nice and expensive. Worth picking out your dream boat house!
