After I put one of those inspection holes (thanks to one sunfish forum member!) in my yet-to-be-sailed sunfish, I found out the foam on the left (port?) side of the mast is not only kinda loose but also tilting towards the mast on the rear. I read the how-to on gluing it back with the expandable foam. Would that do the trick here?
The last picture shows the right side foam in its rightful place.
