They use square copper nails and washer which hammer on with some luck son me holding the dolly on the out side of the boat. Once its tight you burr over the copper nail. The boat will be tarred after.

@@gingertom56 it is amazing to see such a ship being built, but the thought occurred that a dry nail would not have the same ability to withhold the water seepage as would a nail slathered and lubricated with a sealant.

@@nuclearcasserole with clinker boats reliy on on the timber swelling to make the boat water proof. I upset my officer when i stop him from putting our newly refurbished clinker whaler in the water. He though he knew better and didn't tell me when the crane turn up. I caught then just before they loweres it into the water. I had get my offsider to throw a water hose into the boat to prove that is would've sunk straight to bottom. The whaler had been out of the water for two year during it's refurbishment and the timber had dried and shrunk. We had to leave it for two weeks with the hose running into the boat. While the timber to swell. Theres a reason the exhausted from the engine is just above the waterline. So we ran the hose until the water ran out of the exhausted over flow. Once in the seawater the fresh water is slowly replaced with salt water and you don't get feshwater rot. Lucky i took notice while doing my navy shipwright course. Each ski season the timber clinker speed had to be sunk for a week with the engine out of it Copper nail last a long time in water steels useless unless its hotdip gal.

They also hand carved the diesel engine and the GPS navigation.
