Overigens heb ik al eens contact gehad met Finot-Conq over de kiel van een First 22. Onderstaand de laatste reactie van wat mailwisseling. Maar deze informatie is ook wel op internet te vinden.
I've talked directly to Jean Marie Finot regarding the keel bolts of the First 22. Here's his answer : - The
keel is supported by a transversal pin, that is itself supported by two brackets. The brackets are bolted to the underside of the hull. This is a very common system designed by Jean-Marie back then, and that was still used in the last versions of the First
210/211/21.7/Twenty and First 260/25.7/25. - In the First 22, each bracket is attached to the hull with bolts that have a contersunk head in the bracket, and nuts inside the boat. These nut are then overlaminated for watertightness. If this is not how your
boat is, then it has been modified, and there's not much more I can say. - If your boat still has the standard keel attachement, the sensitive points of the keel system are, in order : 1) The attachement of the lifting screw to the aft of the keel. Both the
bolt and the keel itself can be subject to corrosion. Change the bolt, and if the keel is damaged, it should be repaired by bolting two stainless steel plates through the keel and reattaching the screw there. 2) The keel inside the keel box. To inspect that
easily, the boat should be lifted under a crane, the lifting screw detached from the keel when it barely touches the ground, and the boat lifted some more. This will allow the keel to rotate more than its usual range, and provide access to the aft of the keel
box for inspection. Use the occasion to strip the keel to the metal, and reapply a good epoxy paint system. 3) The rest of the system. Remove the lamination over the nuts only and then remove the keel entierly, only if you have reasons to believe that the
keel rotating pin or the bolts are damaged. This is a big job, and should only be done for a good reason. If you do it, then just change all the metal parts (brackets, pin, bolts, with Beneteau original parts !), and the plastic parts if they are damaged.
Then, relaminate over the nuts.
