Note 17 — PRIMO VIAGGIO INTORNO AL MONDO
James Alexander Robertson translation
MS. 5,650 reads: “If he wished the other ships to haul in a bonnet-sail, which was a part of the sail attached to the mainsail, he showed three lights. Also by three lights notwithstanding that the weather might be favorable for making better time, it was understood that the bonnet-sail was to be hauled in, so that the mainsail might be sooner and easier struck and furled when bad weather came suddenly in any squall or otherwise.”
