Watch out
Watch out! Some of the early models were designed with a pin that goes all the way through the centerboard trunk. Later models have a keel hanger which is externally supported by four stainless steel bolts. Take this in consideration to make your plan. Also, it might be posible that the fork terminal that is swaged to the cable is entangled somehow. Another problem could be that there is not a terminal but a loop Nicro pressed, so it might got stuck. What Rich said in relation to the ball is also valid.Be careful, that shunk of steel weights around 550lbs. Do not place any part of your body between the keel and the trailer, because it might get unstuck and ouchhh! It's heavy stuff! Also, do not disconnect the rubber hose in the water. Make a plan and review it! There is a lot of info and links on the C22 Class Ass. web site(www.spiritone.com/~mack/c22). Buy the Catalina Direct Catalog(www.catalinadirect.com). They have lots of info on this matter and the necesary parts to do the job. I just finished redoing my keel with the epoxy method and it requires a lot of patience and perseverance, but the results are worth.Good Sailing!Carlos
