My build has me 'tuning' its position on trailer now, looking forward to launch soon!

To that end, and in the interest of towing safely, here's a couple of links to a method by which one can weigh what their trailered boat weighs with nothing more than a bathroom scale (note that in the latter a 'John Harris' is mentioned so there maybe somthing here on this that I failed to turn up using the -search- function...):

Mayhap this'll help others looking to accomplish the same thing.
