Centerboard Answer
Congratulations on your purchase.I hope that the boat is a good one for you. I have a centerboard model as well and appreciate the variable geometry of the swing keel when reaching.To answer your question, the O'day 22 centerboard is a fiberglass blade, about 4 feet long and wighing about 40 pounds, that tucks into a hollowed out lead shoal keel. The keel hangs below the hull and there's no centerboard trunk in the cabin. The blade is lowered via a pennant (or small line) located in the cockpit.The line should be at the companionway opening to the cabin, at the very bottom of the hatchway step. There should be a little grommet with (hopefully) a small line coming out of it and leading to a cleat located near the cockpit deck. The cleat is mounted vertically on the bulkhead of the cabin and faces aft. There's a tube in the cabin under the companionway that leads from the grommet down into the bottom of the boat. Unfortunately, the tube prevents most coolers from being stowed under the companionway as is traditional for small sailboats.If the boat has been in the water for long, it may need to have the pennant replaced as they will rot with time. If there is a line there, tied off to the cleat, gingerly untie it and pull it up slowly to see what condition the pennant is in. Don't worry if the line is parted or split. It's no big deal to replace when the boat is hauled.If the boat has no cleat, and no grommet, you may not have a centerboard model. Look if there's a line and cleat inside as well. Who knows, perhaps O'day reveresed the centerboard rig through the years they made the 22. Our fellow web members may want to shed light on that issue.The centerboard should come out with the boat when they haul it. If there's no line, it'll hang there (hopefully). If the boat's hauled and the keel has the hollowed out trunk, but no blade, get your money back!If you're not sure about the condition of the centerboard and it's pivot bearing, try to run a line under the bow of the boat, looping it under the boat. With the help of a friend, walk the line aft towards the keel. When you get there, pull up on the line and try to feel your way around to see if you can lift the centerboard into the trunk. If you tie the line off to a railing or stanchion, that will do for the hauling process until you get a new pennant hooked up to the centerboard. The centerboard will not float and will hang there when the boat is in the water.I replaced my centerboard line (no big deal) but that left my boat with a minor humming vibration when near top speed under sail. That's probably from the turbulence around the new line or a loose centerboard pivot. I adjust the centerboard line tension a bit and that usually stops the noise.Any other questions, let me know! We centerboarders are few and far between those "shoalers".Good Luck!
