I store my boat for the winter on a lakefront dock (wood w/fixed steel legs). Last year I pulled the hull onto two bunks and covered w/a tarp, had some snow/ice buildup in the cockpit, despite trying to "tent" it with PVC pipe. Others have suggested that I turn the hull upside down and skip the tarp. Is this better for the hull (avoid depressions from bunks)? Do I need to remove the jibcars to prevent damage? Is there risk of damage to teak coamings; the bow fitting; the mast tabernacle; or the mainsheet swivel block/barney post, from the weight of the hull (I have a Mod 2)? Should I now cover the bottom of the hull with a tarp? Do I need to do anything to secure the centerboard? Any other pros/cons for either method? Thx in advance.
