Were auxiliary supply operations carried out at sea in the age of sail?
Short answerYes. Boats handled ordinary transfers, while tackles, spare spars, and a mast could be rigged into lifting gear for heavier stores.
NotesReplenishment at sea did occur in the sailing era, although it proceeded more slowly than modern underway replenishment. Boats normally carried food, water, and other stores between ships. For heavier loads, crews could rig purchases, tackles, spare spars, and a mast into something resembling an A-frame crane. Seamanship and available time substituted for purpose-built replenishment equipment.
