Another solution is to disassemble the bulkhead and use a small amount of epoxy to keep the bulkhead from moving. Would someone please tell me what Catalina was thinking when they mounted this block in the middle of the foredeck. If you want use what's known as Brady Blocks, which are L shaped pieces of aluminum that have two cleats on each unit. These mount where the regular cleats are with one cleat in the normal position, while the other is mounted to allow you to lock the leeward traveler cleat from the rail. J22's often use these.
