I recently purchased a 1969 macgregor venture 21 foot and it is beyond spectacular. but one problem i have is i live in the pacific northwest and it rains.. a lot! so one of my questions is how should i store it for the winter i currently have it in a barn, but a lot of the time ill go out there and still find water in it. I have been regularly pumping it out but i was wanting a more permanent solution. Also if it will be detrimental to the health of the boat to leave it in there for more than a week or so. Thank you.
