[Rhodes22-list] Boom Room Update Feb 3

[David Bradley]

Art, thanks.  If I'm reading this correctly, your approach would be to
build a frame out of standard SS lengths and fittings.  Sounds doable,
but I'd like to hear from others as to whether a more tailored design
(i.e., some custom pieces to fit over the boom and create the best
contour) would be worth the extra effort.

Is a 5' wide roof wide enough?  I would think that it needs to be as
wide as the gunwales.  Or maybe I'm not understanding your dimensions.

Stan's thought on the side panels is that they would all zip together
then snap on place.  If the sides are a perfect rectangle and the side
panels are divided into thirds, then the side pieces would all be
interchangeable.  But it was Stan's sense that this would be hard to
achieve since there just aren't that many straight lines.  But either
way, there is still some sewing involved.

Again, I'm trying to convey Stan's ideas.  I think he wants a premium
quality boom room "system" that will offer flexibility in
configuration, and be better than an assembly of stock parts. 
Question for the buyers is -- do we want good enough from stock, or
custom designed with a little extra R22 appeal.
