Anyone out there have a Tartan 37 manual? If so, does it have specifications/dimensions for a storage cradle? For that matter, what are the general requirements of a cradle for a 37' boat? Since most of the weight is supported through the keel, how critical is the position of the pads on the hull anyway? My understanding is that the role of the pads is only to keep the hull upright, such that it's weight is directed down through the keel.
