Bill - Thanks for all the data. That said, I owe an apology. In my attempt at comic releif I've created a whole lot of work and distraction.
I have no intention to take out battens, change my prop shaft or to change or do anything with my factory installed stove.
As is, I race with the plastic dry storage bins, a teak and holly sole. all the cushions and a cooler full of Sam Adams - in bottles. When my crew complained about not having the halyard's stripped of their covers because of the weight saving, we took one beer out of the cooler and set it on the dock as an offset.
If we have a weight issue for a one design event, we'll be sailing the boat as built but we'll starve the crew rather than sacrifice any more beer.
