Picnic Cat Spar Specs  Posted by: George Haycraft, Picnic Cat  Mast (DM-284): Boom (DM-275):  Gaff (DM-1): DM-284 Mast  ince we were talking about mast, boom, and gaff hardware, I (George Haycraft, PC#29) thought I'd share this  summary for any who may be interested. All the spars and rigging fittings are available from the Dwyer Aluminum  Mast Co. Go to the page for the spar section you're interested in, and on that page, they list all the hardware fittings for  that spar section. Below are listed the web pages, dimensions, and part numbers for our spars. You can order direct. I  recommend keeping a spare gooseneck or two around. Those cast aluminum horns for the tack and throat pins are weak  points. S  Hint: If you are replacing the mast and stub after unintentionally prematurely folding the mast down and splitting out the  groove, you only need to buy the 12 ft. 7 inch mast section. You can cut three new stub sections from your old mast.  Wonder how I know this ? ? ? NO, how dare you think that !! I just fixed the carnage. The unintentional premature folding  occurred under the previous ownership.  http://dwyermast.com/items.asp?cat1ID=20&cat1Name=Masts&familyID=35&familyName=DM%2D284+Mast  http://dwyermast.com/items.asp?cat1ID=30&cat1Name=Booms&familyID=5&familyName=DM%2D275+Boom  http://dwyermast.com/items.asp?cat1ID=30&cat1Name=Booms&familyID=3&familyName=DM%2D1+Boom  76 Mast length of upper segment is 12ft. 7 in.
