(For those of you who don't get the joke (and yes, this course was actually sailed), you may recall that we sail on the river. Normally courses are sausage shaped, going up and down the river. On open water, people sail triangular courses which allow you to sail on all points of sail (with the wind, against the wind and across the wind). Obviously this isn't possible on a narrow river.
But what if everyone took out toppers (little one-man boats designed for teenagers)? What silliness could occur then? Remember that the horizontal aspect of this course is only as wide as the river!)
