Horizon Cat spars

[bruce]

Com-Pac sources the spars and fittings for all their catboats, and possibly other models, from the Dwyer Aluminum Mast Co.   If it is necessary to replace a part, Com-Pac does stock some assemblies, but Dwyer also offers many components individually. For parts in assemblies, like goosenecks, once you've determined what spar section you have, refer to the detailed diagrams on their website.

To make sure that the correct part is ordered, I asked Dwyer to specify what spar sections are used for the different catboat models. For the HC, the mast is DM-450, the boom is DM-375, and the gaff is DM-2. They also generously provided dimensioned shop drawings that they said I could pass on if I thought they would be useful.
