I have a 1980 C27 which I think may have been the first year with the sea hood. I would like someone with the sea hood model to confirm the position of the mast step casting relative to the upper shrouds. I know it fits into the cut out of the sea hood but would like to confirm the position independently. I have the location centered on the line between the upper shroud deck hardware connection points. Reason I'm asking is that I had to make wet core repairs and have lost my notes on the mast step position. Thanks in advance.
