Hi all I have a 1971 21 ft sailboat that I seldom take out. She sits in dry storage here in vegas until taken out 5-6 times a year.the mast is down and sails are put away but my question is what do I need to do as far as maintance goes on the boat to ensure shes still around for a long time.I take her to the car wash about 2 miles for storage and give her a bath once a month and make sure the trailer wheels are greased and aired up but is there anything i need to be worried about on the boat?
