wA warm welcome here on board also from my side.
I am not a specialist of the Bluenose or schooners at all, I only know that they have, if they have chain and not rope anchors, as so called chain box on deck.
I found a photo on the Nova Scottia page which is showing this box very good
Nova Scotia Archives - Bluenose: A Canadian Icon
novascotia.ca
The windlass was only used for lifting the anchor, but not for falling.....
I'll pull my plans out when I get home to confirm it, but off the top of my head I would concur with Uwek. The chain storage for the Bluenose is a chain box on the deck.
