[Rhodes22-list] Replacing diamondboard pendant

Sun Jun 14 16:10:30 EDT 2020

Well, this is a timely question — I just tightened that last of the 54 bolts holding the centerboard cap in place last night (my boat isn’t in the water). For the second time. I do have some pics. My diamond board was in rough shape. I don’t think it liked Lake Waco.

I am not sure what the best way to attach images is. I am going to try attaching them to this message, but I’ve also shared them on Dropbox here (zipped together):

While I am sure this can be done underwater, I am not sure I would be brave enough to try it with zero visibility. Taking the centerboard cap off and lifting the diamond board out should be done out of the water. It isn’t easy either, but you can see what you are doing.

I have always had the boat on the trailer and removed the centerboard cap - which is, admittedly, a pita. The advantage of doing it with the cap removed is that you get to inspect the centerboard for damage and check all of the blocks to make sure they are still working properly. Mine were not.

Don't overlook tying the bitter end of the new line inside the boat so that you don't pull the whole line through.

Driving the boat onto the trailer should result in the board being lifted automatically by the keel roller but I would want to test this on your rig before committing to removing the line.

The term comes from the old days of sailing when a small cannon was used to fire the messenger line from one ship to another or from the beach to a foundering ship, to be followed up with the larger line.  The technique is still used right up to this day to rig up hose from a tanker to another ship for refueling at sea.  Even nuclear powered aircraft carriers need regular deliveries of jet fuel for their aircraft.
