Sunfish Sailboat Dimensions Diagram How Do I Get Rid Of Water In The Mast And Spars Of A Sunfish Sailboat?

How do I get rid of water in the mast and spars of a sunfish sailboat? - sunfish sailboat dimensions diagram

The boat is a sunfish Alcorta MFA, 1979, when I read the S / N law. Observed water in them in the first race of the year. It seems to go, even if it stops in the final.

Thanks in advance
