I found an old Precision 16 for sale near me that looks pretty clean. However, I noticed that someone mounted a board where the rudder attaches, I can’t find any stock photos of a 16 that has anything like this. Do you think the original rudder mounting holes broke loose and they just did a cheap “fix?” I wasn’t sure if these had a wood core in the transom or not. Any suggestions on how to correctly fix if the rest of the boat checks out? Thanks for any help.
