Does anyone have a drawing of how the mast is stepped to the keel? My mast is not centered in the lower collar -- there is about a 1/8" gap at the front of the collar, and none at the back. There does not appear to be any movement in the mast, and it feels secure. The seal at the deck also leaks (rain water runs down the mast). Before I have the mast lifted, however, I would like to know precisely how it is mounted and locate replacement seals. I have sent emails to Hunter, but so far no response. Can anyone help?
