Hello Scott, I took a quick look through my accumulated Flicka information and I could not find anything which indicated the date PS changed the resin formulation. It has been related to me it was sometime in the late 80's. The point of whether is is more detrimental for a fiberglass hull to sit in saltwater vs freshwater has been hashed about over the years as well. I still have no idea what the answer is. I had pock marks and minor blisters on my M17 hull when I got her in '96. I did a bottom job myself to see first hand what a pain it is. Sanding fiberglass is a nasty job. I applied 8 coats of Interprotect 2000 then 2 coats of Micron CSC. The M23 has Awlgrip on it's hull. I follow your thinking on keeping a trailerable even if you have a "transportable" larger sailboat. That is what I have in mind for my M17. My pipe dream is to have the M23 in Minnesota, and the M17 in the Keys for my "snowbird" winter getaways............someday soon.
