Thanks for the info, I've got the boats out from where they were stored only to find there is a small dent in the Dirigo and some cracks in the fiberglass so I'll have to address those issues first. I was able to locate the # on the hull though its digi0048l84 and there is a stainless or aluminum gromet in the stern, did the rudder just slip in to this or is it fastened mechanically?
