Hi,
Yes I think it is different then larger
rudder.
I could feel the leeboard starting to work, the
rudder is more efficient. That is I could turn the rudder a couple
of degrees back (less rudder angle) and maintain course.
Problem is to keep it on the
guard.
The owner may vote against another experiment he
has to pay for and choose to have a keel instead.
regards,
Rudolf

Will be great tosee how a leeboard works. Do you think the results will be different from increasing the immersed portion of the rudders? regards,rob

Your idea of a central pin under tension sounds good.If the profile of the leeboard starts under the horizontal lower guard the straight side would keepthe board parallel to the centreline at all times. An upper guard should make it possible to have a central pin under tension. Maybe not that much tension, just keep it parallel to cl.Up and downhauls to keep it where you want it.I wouldn't bother with vertical adjustment, it's is enough complication as is.regards,Rudolf.
