I now found out the correct year and other information on my boat it is a 1958 Model F. Next I was wondering a rough estimate of the empty weight of the boat because completely empty mine still weights in the 300# area which seems an awful lot for something that is nothing but aluminum. I also noticed that it feels like there is water somewhere in the boat but I cant really identify where it could be. Just recently patched a poorly filled hole in the bottom and it did take on water very slowly over time but even when the inside was dry I could still hear water sloshing around when its moved and it sits very low to the water no matter what (only around 4 inches freeboard on the transom). So in short how much should this thing weigh and where could the water be hiding? Thanks!
