Since we've spent some time lately looking at modern plywood/epoxy construction, it might be helpful to see how repairs are accomplished with this building method.
In traditional wood boat construction care is taken to insure that future repairs can be made without compromising the structural integrity of the vessel. One of the perceived drawbacks to gluing a boat together as opposed to using fasteners is the difficulty in dissembling the damaged area and resembling with accuracy while also keeping the hull fair.
As we've seen with the design modification of Doryman's rowing shell, there is an inherent tendency for the glued planks to sag once the lap or glue joint is compromised. This is due to the strain on the plank, the lightness of the material and the lack of internal framing.
Last November, a combination of a strong gale and a high tide bashed the St Ayles Skiff built by the Ullapool Coastal Rowing syndicate against the rocks, breaking planks on both sides of the boat. Repairs began immediately and thanks to the efforts of master builder Topher Dawson the glue lapped clinker skiff designed by Iain Oughtred has been rescued.
With a bit of paint she will soon be ready for spring racing off the coast of Scotland.

Nice job, Topher!
