Recently in preparation for the winter, and as part of a regular maintenance schedule, we pulled Clearwater’s centerboard. For those of you who aren’t tall-ship experienced, I’ll try my best to explain what a centerboard is, how it works, and how we pulled it. I’ll let the photos explain the rest.
The centerboard is a 15 or so foot long retractable keel whose forward end pivots on a point inside the hull about a third of the way from the bow. The pivot point is inside the centerboard “trunk”, which is basically a big, framed out hollow in the middle of the boat, a bit like a wheel well. It is raised and lowered by a winch on a cable attached to the after end, at about the middle of the boat.
To pull the centerboard, lines are attached to the tops of the forward and after ends, and then run through blocks on deck. The board is hoisted a little to take the weight off the pin, and then on either side of the centerboard trunk, large metal caps are unscrewed to reveal the pivot point, out of which a large pin must be driven. As you may have guessed, removing these caps allows large amounts of water to pour into the boat, so time is of the essence. Plexiglass and a flashlight are used on either side to line up the openings in the trunk with the one in the centerboard. When you are thoroughly soaked and grateful that you vacuumed out the bilges so the bilge pumps wouldn’t get clogged, you drive out the pin and pop those caps back on. Then you take a breath.
The rest is gravy…lower the board, then run a “lazy line” under the hull to catch the lines the centerboard is hanging on, pull them to the other side, and haul up the board!
