HULA GIRL - SANTA CRUZ 50- BUILD CARBON CHAINPLATES TO WORK WITH NEW CARBON SPAR FROM HALL SPARS

J-WORLD hired GCRC and Doug Frolich of Marshall Yacht Design to spearhead the new chainplate project. The new spar had some sweep in the spreaders so the new CPs had to be moved aft. We started by laminating a hull patch at the new CP location. Then we built a box on which to laminate the CP that would live above decks. Doug Frolich designed a nitronic pin with stainless bushings to accomodate the uppers and lowers from the same CP.


The first order of business after locating the exact location of the new chainplates was to laminate the hull patches and build a quick mold on which we could build the carbon boxes. The boxes have inward flange for max gluing area.


The box being fit. After building the boxes we laminated the CP to the inside and outside of the box.

The CP laminates drape around a tube and then connect to both sides of the inboard face of the box.

Before installing the boxes and chainplates we made sure to core the deck to add stiffness and strength to the area.
     

All sides of the box tabbed onto the hull patch.

The bunk is rebuilt and primer has been applied.


The chainplates at deck level after the full paintjob. The nitronic pin has radiused surfaces so the shrouds align perfectly with the loads.

The chainplates have stainless bushings glued in. The pin ends have caps heald in place with machine screws.
