Adds convenience and security of attachment at the boom to mast connection. Replace the vertex that connects the boom pin to the gooseneck yoke assembly on the mast. Custom made for the Hobie 18, machined from a block of 6061-T6 aluminum and hard coat
anodized. Will not bend and open up no matter how strong the wind. Go a step further and permanently secure the clevis pin that connects that Super Goose to the boom pin with a cotter key. Replace the nut and bolt connecting the vertex to the mast yoke with a 20304 ball lock pin.
