Another wacky Belgian event took place this summer in Dinant. The International Bathtub Regatta is an event in which teams create bathtubs and race them on the River Meuse. Here's a blurb from the website:
Surely the wackiest and most entertaining boat race on earth with over 250 participants in a flotilla of original vessels made out of at least one bathtub racing down the river Meuse. Strictly no deliberate sinking of opponents allowed!
"More of a lark than a serious competition, this event is open to seaworthy bath tubs of all classes, from all nations. The exact rules are vague, but vessels can be of any design — seemingly the more bizarre the better — and there must be at least one bath tub providing buoyancy. Motors are strictly forbidden, so is the deliberate sinking of a fellow competitor. Prizes are awarded by an impartial panel of judges for speed, technical endeavour, beauty, novelty, and representation of the town. Even for non-boating visitors, Dinant, with its onion dome tower wedged between the river and a cliff, is sufficiently picturesque to be worth a visit. "La Regate des Baignoires" makes it doubly so ..." (from worldeventsguide.com)
It was pretty entertaining. There were some creative bathtubs and several of the racers had some fun with the crowd by throwing water balloons, splashing, or pooring buckets of water as they passed by. I thought it was quite amusing to watch them try to paddle the boats with various objects as well.
