I'm well into my Minifish restoration. I weighed the boat, 120# and everything I have read states the weight should be in the 80# range. I installed two deck ports for ventilation. One is just aft of the mast and I hit open space the other is forward of the rudder and I had to cut away some foam to access the forward/aft open space. When I cut into the foam it was soaked (boat has been under my deck for approx. 15 years) . I set the boat in the sun with a small fan this past weekend and the foam I can reach no longer feels wet. I will be cartopping this boat so I would like to shed as much of the excess weight as possible. Now to the question - The plastic plug at the bottom of the mast came out when I took the mast down from it's perch in the garage and 4 round dried -out pieces of cork also came out. Does anyone know if these are important? Where should be positoned in the mast? Any help will be appreciated.
