While sailing Shackleton, I’ve had quite a bit of water coming through the CB bolt into the BH 4-5 area. I attempted to silicon the bolt head, but to no avail. Then while talking with John Welsford at the Skills Camp, he said all such problems can be easily fixed by using an O-ring.
This is much nicer looking than the first cap, is secured with three screws and hopefully will solve the water intrusion problem. I had to temporarily remove the vault lid (containing the fixed ballast) to get straight access to the cap.
Thanks to John Welsford for suggesting this easy fix. Doesn’t it just look much nicer? Can’t wait to see if it works.
