Hydro: Scuppers



This weekend we cut holes for the port and starboard scuppers and glassed it up.
Since this area will most likely be constantly wet, we took extra care in sealing up the holes.
After the holes were cut, we saturated the raw ply with epoxy.  The transom is made of (2) 3/4 ply wood epoxied together.
Next we cut thin wall PVC tube to line the holes.  The tube was abraided with sandpaper. The tubes had a slightly loose fit so we wrapped the tube with glass tape, saturated it and twisted it into place.
We left the tubes slightly long.  This allowed us to wrap the ends with carbon fiber tow and press it into the seam with a screw driver.
Today the lamination was hard so we sanded the tubes flush.  It looks like a solid connection. Over the season, we will monitor the integrity of this joint.
This is the sanded flush starboard scupper.
This is the glass tape and CF tow we used to wrap the scupper tubes.
This is the interior view of the port scupper.
