Hull-to-Deck Joint Repair - Photos
| The recessed rectangle is where an aluminum plate was embedded in the
fiberglass skin. This apparently functioned to distribute the load
of the stanchion to prevent compression of the balsa core. Once
water penetrated through the stanchion bolt holes, the aluminum corroded,
the balsa core deteriorated and the entire area failed, allowing more and
more water in. Note: when finally removed, the aluminum plate
was severely corroded, with layers of scale on the surface of the
aluminum.
Hull-to-Deck Joint Near Scupper: (starboard side) This picture clearly shows the separation of the bonding of the polyester infill at the bulwark. Being a bonded joint, integrity of the adhesive infill is very important. Once the joint fails, water gets in, freezes and thaws, causing the separation to travel further and further. View of Hull-to-Deck Joint: One more view, starboard side looking aft. View of Old Joint Next to One Repaired Area: port side. This is a view of an area of the joint in which the inner skin did not have to be removed to effect the repair. Click on any of the thumbnails below to see an enlarged photo. (Note: photos were taken while boat was covered with a blue tarp to keep deck area dry).
