what besides carpentry does the ship carpenter do

From the text:

"For not to speak of his readiness in ordinary duties:—repairing stove boats, sprung spars, reforming the shape of clumsy-bladed oars, inserting bull’s eyes in the deck, or new tree-nails in the side planks, and other miscellaneous matters more directly pertaining to his special business; he was moreover unhesitatingly expert in all manner of conflicting aptitudes, both useful and capricious."

In other words, he was a man of all trades.
