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.
REad the message I left previously. It WILL work with this particular vintage Lightning. It's DESIGNED to allow the CB to be removed while resting on the trailer. Lifting the boat and trying to remove it through the bottom is much more difficult and potentially dangerous. Just be sure you put something underneath (between trailer and bottom of boat) in order to prevent the board from falling on to the trailer or on to the ground. The pin upon which the board pivots is removable from the inside. The board is heavy, and you want to fasten something easy to hold on to through hole in the top. I have done this at least 20 times by myself, and I'm no athlete. A helper might reduce anxiety

Re: Lightning centerboard extraction

As Sonosail posted in post #9 of this thread, the top of the centerboard trunk can be removed allowing you to extract the centerboard; all 130#'s of it. I checked with the International Lightnint Class.org website for the One design specs on this boat.
On the Lightning I owned I remember a wood cap over the center board trunk probably made from Mahogany wood and bunged in. You would need to find and remove all the bungs, then the screws beneath them and remove the entire board to reveal the center board trunk. Extracting it is then just a matter of lifting.
Sounds easy enough.
Yeah right.

Re: Lightning centerboard extraction

I, for one, (and I know, others do too,) appreciate the helpful comments you regularly make on this forum.
In this case, you must be thinking of boat other than a Lightning. (or possibly a really old wood one?)
I've owned 3 different lightnings and sailed on at least 20 others. I also owned one from this same builder and vintage, and performed this same task at least 20 times.
Not necessary to take anything apart. (only the pivot pin when when you ready to lift the board out.) Slot is open at the top. No cap. The board is somewhat heavy. But unlike many other boats, someone actually thought about how a single person would take the centerboard out without too much effort.
I haven't owned a Lightning in years, and since I have this sailboatdata.com thing, I never get involved with recommending any kind of boat. I will say, however that the Lightning (designed in the 1930's) is the most well thought out boat I have ever owned. I just remember thinking after launching a Laser for the first time, how much easier everything was on the Lightning. (not a useful comparison for most, ..initial impression only.)

Re: Lightning centerboard extraction

The going price for a used, SS Lightning CB is about $1k. If it were mine, I wouldn't touch it with a wire brush. Strip it with methylene chloride paint stripper. maybe use a 3M pad with stripper to get off the last remnants.

Not that I'm recommending it, the CB will fall out if you invert the boat; gravity is holding it in. The TCA Class rules require a restrainer to keep them from falling out f the boat turtles.

Re: Lightning centerboard extraction

I owned a Lightning for years and had the steel cb out a number of times. It is not at all difficult and can be lifted out by one person although two would be better. I would just scrape what I could with a regular sharp hand scraper and then get a belt sander on it with some 120 paper. It's not a polished surface and needs some grip surface anyway if you're painting it again. I've seen the cbs in steel and bronze. Never saw one made from stainless...nice. Why paint it at all if trailering? I painted my cb because she was moored and, being steel, was prone to rust.

Forgot to say that I removed mine when the boat was upside down. This makes for fewer potential problems and less chance of messing up the trunk and brightwork. Remove the top stop and it will slide right out once the pivot bolt is taken out. They are fairly easy to flip over and block up inverted.

I owned a 1967 Clark frp Lightning for only about 3 years. I was mis-remembering as you are quite right that the board sticks out of the slot into the cockpit as it is adjusted up or down. I also never removed the center board so I have very little credibility posting to this topic. I have also owned other smaller sailboats than the Lightning and I am over 50 so I am likely confusing a few boats together... ;-)

But hey, it is the internet and you should always have your BS meter on high alert reading most forum posts, mine included.
I defer to other, more long time Lightning owners on this subject.

Thanks for calling me out on that!

Re: Lightning centerboard extraction

The minimum weight of a lightning is 700lbs, and the centerboard accounts for a small but good percentage of that weight, so unless you need to remove the centerboard I would first launch the boat and see how it operates. If it drops down then you are all set and go sailing!

At the forward end of the centerboard trunk you will see a pin which the centerboard pivots on. The distance from the pin to the aft end of the trunk is about how much the centerboard will stick down underwater.

Our club used to race those boats and I don't recall a centerboard ever having a problem. What I would suggest checking is the state of the lifting cable, especially where it attaches to the centerboard.
