Re: Birdwatcher keel- Nels
I think that you will want the bigger board with the solent lug BW.
The BW1 board was sized to go with the original leg o' mutton of 125
square feet. The solent lug mainsails for the BW1 alternate rig and
the BW2 are practically the same, 144 and 142 square feet, suggesting
the bigger board. Whichever version of the jib that you use does not
matter for the board decision. It is really best for reaching. When
reaching, you do not need as much board. There is too much sag in the
luff to carry even the small one to windward if there is any strength
to the wind. Just hauling the jib halyard bends the mast noticably.

If I did that I would still use the centerboard design for BW2 -
just that with the smaller sail area it could use a smaller
centerboard I think. But maybe not.
I am also considering the idea of sealing up the centerboard case
opening altogether and adding chine runners instead, and trying it
that way first:-)
Thanks for giving me the heads up about installing the insulation

I am actually considering convincing my Swedish cousin to build one

I am still working out the details on the Long Micro modifications I

I have to stop talking to these crazy Bolgermaniacs!

No, that is not what I meant. I ended up purchasing the smaller
sized solent rig sails from another member that were originally the
upgrade for BW1. But which I would use for a BW2. In discussions
with him it seemed that I could then install a somewhat smaller
sized centerboard than required with the larger BW2 sailplan. This
is only speculation at this time as I only have BW1 plans.
If I did that I would still use the centerboard design for BW2 -
just that with the smaller sail area it could use a smaller
centerboard I think. But maybe not.
I am also considering the idea of sealing up the centerboard case
opening altogether and adding chine runners instead, and trying it
that way first:-)

Hi Nels,
You recently wrote of your choice to build a BW2, which I was very
excited to hear about. You also mentioned, if I read it correctly,
building it with the BW1 off-centerboard and at a later date changing
out to a BW2 trunk and board.
I was wondering what benefit you'd gain? The BW2 trunk and board is
longer than the original, and coupled with the redesigned rig, seems
to extend farther forward than the original. I don't have the plans
for BW1, only BW2, but I've seen photos of the original board set-up
which had a pin/bolt running through trunk and board. BW2's pivot
mechanism is self contained inside the trunk, so no piercing of the
trunk and thus potential leaks. It seems you'd have some major
recipricating-saw work to change from one to the other, besides having
to build a trunk and board assembly twice. Just curious.
Also, in terms of the foam, I'd think it would (thermally) add to the
comfort and length of your sailing season. Besides, as one who has had
to glue it in TWICE, I can attest that it's easier to install without
the windows and longitudinal upper framing in place!
I keep contemplating how to portage a BW2 in the UC....Lets see, class
4 double male with a folding tandem bicycle and hull wheels a la Matt?
OK, beefier tires!
Take care, let us know how it gets on.
