How to Have Your New Rudder Weighed and Measured

First, you find something high enough to toss a line over. Then you fasten you scale and rudder to it and hoist it up. Read the number on the scale and bring it all down.
Then make a trailing edge measuring tool and see if the factory made rudder is legal. Seems a bit silly to have to do this with a rudder that's like the one billionth produced specifically for the Folkboat, but since I'm a suspicious person, likely to cheat at any opportunity, better check to be sure. ;)
Good news! The rudder passed! Now off to other, more pressing boat projects.
