Centerboard vs. Shoal keel
Hi Ed;I have a 1979 Oday 22 centerboard. The centerboard fits into a hollowed-out shoal keel of lead. The shoal keel is very similar (if not identical) to the keel that is offered on the shoal draft (fixed keel) models. I've heard from folks who owned shoal draft 22's and they noted that the centerboard model performs better in terms of pointing. I can attest to that opinion as my boat's best point of sailing is on the reach.The centerboard is very easy to use and is simply built, making maintenance a non-issue. Just make sure the pennant line is in good shape when you launch in the Springtime. The trunk is entirely outside the hull and is easily cleaned (when the boat's hauled) with a simple scraping tool. Just make sure that the boat is chocked up high enough for the board to drop clear of the opening into the keelThere's no pulleys or gizmos to aid the lifting of the 60 pound board, and it's relatively easy to do. Don't try to lift it under load though, as the effort is doubled. The only drawback is slight turbulance around the pennant line while reaching in a strong breeze (humming and high pitched vibrations) as well as the pennant tube protruding into the space under the companionway step. Other than that, the centerboard adds a great deal of flexability to the boat and is great in heavier winds. In light winds, you really don't need it as it tends to rattle around in the trunk when the boat is rolling.Hope that helps,Happy Sailing!Stu Timm"Karakahl" 1979 Oday 22 CBCenterport, NY
