He is the son of Poseidon and Amphitrite, god and goddess of the sea respectively. ‘caulked’ might mean ‘the ancient staggerer, the vine-juice skipper’ (page 182), i.e. ’strengthened’ in an ironic sense.

He was known for wearing coats made of grogram cloth, earning him the nickname of Old Grog, which in turn came to mean diluted rum.
