Where do you attach the bunge? Comments, ideas welcome.

An excellent idea! It would be great if some of the mechanical engineer
types would take this on as a project. It would benefit the entire group and
possibly the manufacturer. The through bolt idea is not a great one as
Judy's <and others'> recent experience(s) will attest. Another good
'engineering project' would be to do the same for the P-15. A weighted
centerboard is likely to come up during a capsize if not held down by some
means and can cause the boat to turn turtle. A properly sized and placed
bungee will no doubt do it, but what is that size and placement? OK
engineering types, whadaya say?
