Re: [bolger] Bar to hold leeboard against guard?
I've built two of Michalak's boats--a Mixer and a Toon 19--both with the single leeboard arrangement described. The combination of the lower pivot point combined with the upper guard holds the leeboard in a single plane and allows it to pivot parallel to the centerline of the boat. This arrangment works fine and is both easier to build and less likely to leak than a conventional dagger or cnterboard. The single lee board is, of course, asymetric, but I have been unable to identify any difference of performance on either tack. Possible disadvantages--the lower leeboard guide drags in the water, makes splashing/gurgling noaises, and probably adds drag; the arrangement looks crude; as the boat heels away from the leeboard, less board is immersed (primarily a problem with wide boats which are not sailed flat); and the use of his arrangement is limmited to boats with vertical sides or with limited flare.
I've owned a Sea Pearl (with lee boards that flop out and need to be tended on each tack), a Dovekie (with heavy lee boards which I found difficullt to raise and lower), and the two Michalak boats. Obviously, I like leeboards and of the types I've tried, I like Michalak's arrangement the best.

Hello:
Jim Michalak details a scheme that he says was used on Bolger's Otter in his 6/15/98 newsletter (and probably repeated annually thereafter, although I can't tell from my personal index). The board pivots on a lower external guard and the top is held with a slotted guard at the gunwale. There is no need for anything on the outside of the lower guard to restrain it. Works on both tacks, only one board needed. Looks neat to me, but I've never tried it or seen in operation.

Hello,
Has anyone experience of using a bar or rope running outside the
leeboard guard or slotting the guards so that the board is held in
position?
This means a long guard so the tip of the board can clear on lifting as
far as I can see but apart from that what advantages and disadvantages
are there?
I think I remember that one of the Chapelle books shows this for some of
the large garveys used in the late C19 on the US gulf coast. Some had
just one board carried on both tacks.

On a 16' sharpie of my own design, I use a slotted guard just below
the gunwale and a standout just above the waterline in order to place
a swinging leeboard far enough forward to get slight weather helm.
The short leeboard handle stays within the guard when the board is
pivoted upward, and a narrow oak strip with a line on it is inserted
in the slot to hold the board clear of the water when needed.
I will post pictures of the design. It seems to work well, although
the lower standout probably causes some resistance when immersed. I
don't notice that problem when sailing the sharpie Essence, however.
