Repairing Redwing frames, ribs

Pintail has a few broken ribs and to repair them I decided to try this as with her deck on it would be impossible to feed a new steamed length of timber down behind the inwale and riser. There were four broken timbers that had failed at the point of greatest curvature and stress. There were two together on the port side in way of her chainplate that could not be ignored and a couple on the starboard side. New oak was cut to the Redwing scantling of 5/8" by 1/2" and long enough to overlap the break. These were steamed and clamped alongside the broken frames as shown. Now, I am not 'sistering' these frames - after a couple of weeks to dry out I drove out the fastenings of the lower part of the broken frames and cut a long scarf which was glued with Semparoc as we re-fastened, as shown. This is a bit of an experiment but it saves removing all the rib in an inaccessible part of the boat.
