On our 35-2, the area around the mast collar had wet core, and was repaired (drilled & filled with epoxy) by the previous owner 20 years ago. This area is now very solid, basically all epoxy. The mast collar has 4 bolts through the deck, but also a SS strap on each side, and these are connected below decks with a bolt though the mast, so most of the upward force on the collar is transferred to the mast, not the deck. Just had the mast out for the first time in 20 years when the work was done, and it still seems very solid.
Possibly adding the straps between the mast and collar (if they are absent) might help with your deck compression issue. -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Wed, Jun 9, 2021 at 10:06 AM Steve Thomas via CnC-List < cnc-list@cnc-list.com> wrote: > I have a C&C36 MK1, 1980 version, with the same problem.
