Dave Does the CB as installed stay completely in the keel when fully deployed or does the trailing edge come out below the bottom of the keel? Are their any working diagrams on the keel/centerboard system? Can any of the centerboard work be done in shallow water thus preventing having to lift the boat?

I have a tubular check valve that I tested last year. I would have to install it behind a new stainless rope tube to help prevent water from entering along the rope especially after blocked by the check valve. But now I am considering plan 'B' with decreased but probably usable access to the rope (pennant) from the cockpit area.
For plan 'B' I would epoxy the rope tube to the back of the drain opening, and use a brass plate with a check diaphragm to block reverse flow. The brass plate would have to be inset and sealed into the deck around the aft portion of the drain area, and also be removable to get visual and finger access to the rope(not for lifting the centerboard, but possibly pulling it out of the tube and sending it down around centerboard. The tube is flared at the end to reduce any chaffing of the rope, and it goes from the middle of the cabin step board, down to about an inch below the top of the drain. Of course there's not much room to work in that drain area and I'm not very skilled with fiberglass or epoxy. I don't think ost experts would want to do it. But I think a full solution is possible. I really hated being out on Lake Michigan last year with two crew, when wave action caused cold water to come in and settle in the back of the cockpit, and we chose to cancel.
I read the other remarks about the centerboard below after sending. This isn't my primary email, but I expect to get here more frequently during the summer. I have made a lot of improvements in the boat, including a Lehr long shaft propane outboard and a trailer extension.

Keep us posted. How do you intend to drain the cockpit?
I can not get the CB to fully extend. I need to get in the water and see if I can un-jam it. Waiting for warmer weather in NW Indiana (50 mi east of Chicago)

I am considering a change to that would involve blocking the cockpit drain and running the rope through a stainless tube, but first want to know if the rope an be replaced from the bottom, but just pulling the rope up through the tube (using a wire for example).
What is involved in replacing the lift rope?
