Known as the "Chippy" the ship's carpenter was better titled the Shipwright and was still borne on the books in the 1980s at least. Whilst he could work in the limited amount of wood to be found on board, he was everything from the ships metal worker, welder, engineering jack of all trades unless it had wiggly amps in it which used to make the chippy break out in a cold sweat.
Elm, jolly good choice for a chippy as old sailing ships keel's used to be formed out of Elm as it was fairly resistant to splitting and was reasonably durable. Victory's keel was elm.
