Lightning centerboard extraction
 
Lightning centerboard extraction
I have lightning and am wanting to extract the centerboard to remove the paint. Any suggestions on a one man extraction? Is it possible to extract with the boat on the trailer?

I don't know about trailer extraction but with some inguinuity you can do it. You need some jacks to raise the keel a few inches above the width of the center board. I take mine out periodicaly and alway's tell the yard to leave me sitting high enough to wiggle the CB out. there is nothing one man can't do with come alongs, jacks, patients and fore thought.

So the CB needs to come out from the bottom correct?

Ya, there will be a bolt that it pivots on. They were installed with extraction in mind, very simple set up.

Any tips on getting the paint off the stainless steel CB?

The CB on a Lightning is supposed to weigh <= 130 pounds. ILCA Lightning Plans and Specifications

Probably be easier to extract the CB in shallow water on a calm day. You need to find and remove the pivot pin in the CB trunk.

I'm not sure if this is feasible or not but you could remove the cap of the CB trunk in the cockpit. You might be able to jigger the CB out through the top. I doubt this would work with the boat lying flat in it's trailer though. You'd likely need some wiggle room.

Another thought is to dump the Lightning onto the ground, prop up one side and dig a trench under the CB.

Good luck.

Wire brush on a drill.

The board comes out of the the top of the trunk somewhat easily. Replace pannant with something easier to hold on to and fasten it somewhere so the top of the board doesn't go below the top of the trunk. Wedge something like a cuchion on the trailer brace to restrict the amount the board can be lowered. Lower board. Remove pivot pin and carefully wiggle it out.
The standard steel (or ss steel) board is heavy, but one, reasonably strong person can manage this task. An extra person can make it a little safer.

Re: Lightning centerboard extraction
 
I have recently purchased a Lightning (1982 nicholes boatworks variety). I am new to this boat type so I am not quite getting in my mind the picture of the centerboard removal. Terms are important but is there a diagram anywhere or pictures on the internet for me to become enlightened? I have yet to take the boat out until all is clear in my mind. I've even thought about suspending the boat off the trailer to drop the board for examination and removal. I have an extremely sturdy garage frame that I can back the trailer under to do so and a 1 ton chain hoist begging for something to do.
