The keel will be 2500 mm x 500 mm deep. Probably 150mm wide.
I want to use a stretched Proa 3 series foil shape by Tom Speer.
It should have two threaded rods to fasten it trough the bottom of the lw hull.
That should make it possible to lift the boat fit the keel a put it into the water within a couple of hours.
We'd use a sealant at first. After testing the keel could be glassed and finished properly.
 
regards,
Rudolf

Hi,

We sailed BD again with the repaired leeboard.
I fixed it to the lw hull with a Dyna One line through the hull side to the mast frame. There were a lower and upper guard to keep it in position, at least that was the intention. It appeared very hard to obtain enuogh tension on the line to keep the board thightly next to the hull. A bolt would be better.
Results of the sail pretty much confirm the earlier ones.
I asked somebody new to the boat to come along for the test.
When we where less concentrated on sailing the boat (too busy talking)the board would come off the lower guard and after that it was hard to bear away and the boat luffed into the wind a couple of times.
Next day I sailed with the board of the foundation owning the boat and
After a while the line connecting the leeboard to the hull broke.
Now they could see with their own eyes the difference between having the leeboard and not having it. The boat would luff into the wind when steering higher that a close reach.
For simplicity they prefer a keel as I expected.
The extra hassle of uphauls and downhauls and keeping an eye on the leeboard is more that they care for.
So I will try to get a keel under the boat before winter really kicks in.
Regards,
Rudolf
