The aft section of Riverkeeper’s chine log showed significant rot and needed to be replaced. Replacing the entire chine log was not necessary, so the aft end of the log (approximately four feet) was removed and a new white oak piece was scarfed in.
Carlos and I discussed the different types of scarfs found in boatbuilding, including plain, hooked and keyed. We also talked about proper thickness-to-length ratios. This scarf that Carlos worked on is a plain scarf with a 10:1 ratio.
The scarf was then glued with GFlex epoxy.
