Although I'm not a sailer myself, I do enjoy time on the water, and appreciate those who have their own boats.
But when parking a catamaran on the street, is it really necessary to leave the rudder blades sticking straight back? Every time time I drive by the one parked on Touriga on my way to drop off my children at school, I think of some child riding their bike and potentially running into one of those blades. It's like the owner is aiming a sharp knife directly at oncoming traffic, right at face level. Someone could be killed!
Aren't there rudder blade covers that you can put on, or a foam bumper? Or I don't know if this is possible, but can't you just turn the rudders sideways so they aren't pointing right at someone in the bike lane.
I know people should be able to avoid obstacles right in front of them, but I've seen my kids run into lots of things, and I would hate to see anyone smack into something sharp and metal and pointing right at them.
If you have a boat parked on the street, please do what you can to make it less of a hazard to people riding or driving by!
