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
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.
