To raise a heavy anchor:
Lash two boats together. Put a round beam or spar across the gunwales and ship a couple of hand-sticks in it so as to turn it like a windlass. Take the line on the anchor round the spar and turn, winding it slowly up. Keep the beam from rolling out of place by two guys, one at each end, with an eye over it. The guys want to lead from the end of the boat on the side that the rope from the anchor comes up.
