I have recently acquired a Holder 12 sailboat made by Hobie Cat that is in excellent condition. At some point in time however, the upper mast was lost and I would like to find a replacement if anyone has one. Failing that, could someone please provide the upper mast specifications. The overall length, the outside diameter, the wall thickness/inside diameter of the mast. In addition it would be helpful to know the distance the collar is from the top of the mast. I am assuming the upper as went inside the lower mast up to the collar. With this information, hopefully I will be able to purchase a piece of aluminum tubing as a replacement. Surprisingly Hobie Cat was unable to provide this information and suggested this forum.
Thank you in advance for any help.
