These are photos of all glass Parker 505 7678, as it was being dissassembled by George Saunders, who recently purchased it, and chose to make some significant repairs. The first repair (compass holes in seat tanks) is shown. We expect to have more images added as work progresses.
Close up shot of compass mounting hole. George decided to reduce weight by going with a single compass rather than the two - sunk into the seat tanks - that came with the boat. Both compasses were badly scratched and hard to read. They had been mounted with epoxy, so removing them caused some minor damage around the mounting hole. This is a close up of the hole in the port seat tank. A portion of the port shroud extension turning block can be seen in the lower left of the photograph.
A jig was used to hold up the first - inside - layer. George made a thin layer for the inside, and used this jig to force it to conform to the tank shape, while on the inside of the hole. A layer of microballoons went over the inside layer, then another layer of glass over that. George made a mold to shape the top layer using an adjacent portion of seat tank as a plug.
Close up of the repair. The repair after glassing but before any color and cosmetic work. You are looking at the starboard tank, facing forward. The turning block for the starboard shroud is in the upper right of the photo.
Prior to closing the compass mounting holes, the area near the shroud turning block anchoring points, inside each seat tank, was carefully checked. The rail is heavily loaded at this point. Both sides were fine, and neither required any repair or reinforcement.
Photo of centerboard cap The core in the centerboard cap had crushed in several places, and fittings were pulling out. When George opened it up, he discovered a rotten, waterlogged balsa core. This photo was taken after a portion of the top glass layer had been removed, exposing some of the core. Balsa is normally light in color; the dark in the core is all rotten - and water saturated - core.
The tops of the thwarts, the mast step, and the twin shroud lever system can all be seen in this photograph. They were all removed after this photograph was taken.
Close up shot of the rotten balsa core. Not a pretty site!
The centerboard cap portion that has already been removed is lying on the bottom of the boat. You can see numerous holes were drilled in it. This was from an earlier effort to dry out the core, and inject epoxy through the holes to reinforce the centerboard cap.
More of a close up of rotten balsa! When balsa goes bad.....
Note the use of fiberglass mat in the layup (you can see it where the top layer of glass is still partially in place).
Photo of centerboard trunk and thwarts with CB cap and step removed. George is rebuilding a new cap and thwart top out of laminated wood, epoxy and carbon fiber. He also took the opportunity to remove the Parker standard shroud tension levers. They did not have enough travel to allow low rig tension at the 25' 8" rake setting and tight shrouds " at 25' 2" " of rake, as the North American rig tuning sheets suggest.
Most of the pieces removed required minimal cutting, and came out with George's bare hands.
If you compare the thwarts with the earlier images you will note that the molded fiberglass tops of the thwarts have been removed, and the polyester gelcoat that the wooden thwarts were "painted" with has been sanded off removed. A small amount of rot was discovered underneath a fillet where a thwart was bonded to the boat. Fortunately, the rest of the wooden thwart structure was fine, and new wooden thwart tops will be bonded to it.
All wood should be sealed with epoxy!
Remaining portion of mast step. The centerboard trunk cap extends forward, becomes part of the mast step, and stops at the watertight bulkhead. The new cap will come foward all the way as well. The new structure will be wood, and will bond to the structure that was left.
The repair around the shroud turning block anchor was done by the first owner. Most of
this series of boats have required that repair, as the wood where the shroud
turning blocks were anchored rotted out.

The picture illustrates some localized rot found behind one of the polyester fillets..
