Took my new (1974) boat out a couple weekends ago. Had a blast and everything worked great. When I got it home and put it in the garage to clean it up, I noticed that the mast had water in it. I read in another thread about a draining mast. Is this an option or do I need to replace the caps. Thankyou for any input. I havent posted any but have gotten lots of info about my boat.
