Keep mast raised when not in use?

I am looking at keeping my 1982 Hobie 16 at a marina where there are a large number of other cats (Hobies, Nacras etc.). The boats are kept on special made floating docks so they can be easily slipped into the water. My question is would it be okay to leave the mast raised for the season? The thought of trying to raise the mast on a floating dock is not appealing, even with a assistance. The other boats I saw there all had thier masts raised, but I remember reading that the mast should be lowered when not being sailed. Any input would be great. Thanks!
