I just purchased a Sirocco C-13 very inexpensively on ebay. It was made by Sirocco Boatworks and Fiberglass Co. in Oshawa, Canada. The company is no longer in business, and I, unfortunately, lost the masthead on the trip home. Dwyer aluminum mast company has an mast extrusion that is identical in shape, but slightly too small (DM-2). Can anyone direct me to where I might find one?
