No doubt others have asked this question but I have looked through most of the information here and can't find an answer. I sail on Morton Bay in the famous Morton Bay chop. When beating or running I hear my board moving about in the box making quite load thumps. Is this a problem? Does it stress the pivot bolt area of the board? should I worry? If I have to take the board out, does it go up or down. I guess you can tell I'm a new RL24 owner and new to trailer sailers I'm used to sailing things with training hulls. Regards, Martyn
Martyn my RL24 had a bad case of keel knock and I fixed the problem by gluing to sheets of laminex on either side of the keel using Aroldite. I cut two slots where the bolt is situated and slipped the sheets of laminex over the keel bolt. You will need to remove the top of the keel case to do this. The laminex goes right to the top of the case, so I could get some glue behind them. I did this more than 10 years ago and there is still no movement in the keel.
Martyn. Dont be too concerned by your keel knock, it is only anoying and difficult to stop completly. The keel hole is 2mm bigger than the bolt and all the stress is taken on the boats keel ( which is about 20mm thick) and the case sides. the bolt is only a pivot point. Just make sure you are not lowering the keel too far, it should rake aft about 20 to 30 degrees.
