[bolger] Re: Inventing a New Rig
It could definitely be done. Some fine points about this really neat boat:
I spent much of one Sail Expo St. Pete studying this thing; The rotating
mast with a sleeved sail wasn't all that new. Sea Pearls (one of the SBJ
staples) had this feature back in the eighties. The hard part is the
geometry of the boom rotation. About the only way to execute this in an
owner built boat would be to really design (like Mr. Carlson, using real
drafting tools, not like me with legal paper and a ruler) a weldment with
fittings to bolt to a false bottom (like one of boger's mast steps) that
would precisely locate the angle of boom vs mast. The only hard part after
that would be the bend in an aluminum tube to form the boom.
I'll see if I can get some pics at this years' Sail Expo (next weekend).

Good idea.
The Escape's, I think, have two adjacent tubes that could be built of pvc
tubes (or Nylon or Delrin, if you could find them) glassed in place in a
copy. The boom tube provides support for the boom with the sail furled.
I suppose you could do the same by welding your boom to a plastic-lined
tube of reasonable length - 8 or 10 inches? - and sliding this over the
mast. Or, the boom could be supported by a rigid vang or swiveling topping
lift.
I would think, though, the original 2-hole design might provide less
friction and would be easier to build.

Dear Bolgerista's,
Recently, while sailing my Windsprint on a nearby lake, I saw an Escape
sailboat for the first time. If you are not familiar with this little boat,
it is a modern dinghy made out of poly, professes to have a shape which
inhibits capsize and features a very interesting sail plan. It is the sail
plan I wish to speak about.
The sail of an Escape is under 100 sq. ft. (there are several sizes of these
boats) but for our conversation we'll talk about a sail that is 100 sq. ft.
in size. The sail shape is similar to a Laser and like a Laser, I believe the
luff of the sail is a sleeve into which you insert the mast. Here is where it
gets interesting. The mast and boom of the Escape are separate. The boom
actually is mounted just behind the mast, starting in a vertical then quickly
curving to horizontal. The foot of the sail is loose. This setup allows the
single sailor to furl and unfurl the sail around the mast. The Escape sail
plan is totally adjustable to the wind conditions. I haven't gotten close
enough to an Escape to see how the furling line works, but I've read reviews
about it and they say furling and unfurling is easy.
Wouldn't it be great to figure out how to adopt this rig for the home builder
of small sailboats? Surely someone out there can figure this out? Here's a
thought I've had about it:
The mast rotates smoothly in it partners. The boom is attached to the mast
via a ring or hoop which slides down over the mast and rests on a spool
attached to the mast just above the partners. The outhaul of the sail is lead
from the clew through the aft end of the boom and back to the spool where it
is wound up when the sail is hauled out and of course, rotates the mast
causing the sail to be furled when the line is pulled out.
Can this or something like it work?
