10/22/2017 6:46 PM Pacific Time My boat is a mk 1, today while doing some bottom prep for next season I noticed my hull flexes when pushed on basically in the area below the rear bench on the dining table side between the keel trunk and the trailor bunk. I have not noticed this before the boat just came out of the water last week for the season , is this normal and I just haven't caught it? Anyone ever came across this area as prone to flexing due to the large span in the liner and no tabs glassed in there. My worst case assumption is delamination but there is no cracking sound, just flex.
