Randy,Usual winter storage is just a little short of what I would do. Unless the batteries are new you will need to replace them when you return so might as well take them out and get rid of them. You migth want to "oil" the pistons (fogging oil in each injector). A boat that is sitting a long time also becomes a target for thieves so remove every thing and anything that you can. Cushions,bed, bedding, sails,all gear etc etc Don't leave anything on the boat that could be stolen. I am guessing you will have the mast down,you need to make sure the boat stands are in the correct spots so there is no hull "oil canning" you might want to think using some extra stands. Make sure there are plently of vents in the shrink wrap,more will be better in a long term storage. I'm sure some others will have more to add but you might ask a family member or a boat friend to check it at least once a month if not very other week if posible. Make sure the yard has an emergency contact in your absence. I am assuming you are in the service and will be stationed overseas ("duty calls") If this is true THANK YOU for your service and may you come home safe and soon !
