Re: Before - Seabird '86 isometric

Does anyone know if a wishbown mast has been used for a dipping lug
(although with the wishbone you would not have to dip...)? I have been
thinking about this rig for a long time, although I think I would go
two straight uprights with a lateral crosspiece at the top, to reduce
the binding downwind problem.

Such a rig would be really easy to set up on any of the box boats
because of the straight sides. It would seem to offer all the
advantages of the dipping lug without the dipping!

II agree. can think of some other reasons the wishbone mast might be bad.
One, rigging the halyard would be a bit complex.
Bruce,
I noticed the wishbone mast just before the Seabird 86. I asked Phil
about something similar (an asymetric mast on one side) for the Fast
Motorsailer and he replied that I should just consider the balanced
lug. Over and over I hear that people can't detect a difference in
good vs bad side sailing or even that bad side was faster or pointed
better....

Looking at the wishbone I'd have concern about down wind sailing. It
seems that one approaches having the yard bind in the wishbone as one
goes farther downwind. Almost the same was true for my scheme on the
tack with the sail on the side that the mast was on.

Sincerely,
Gene T.

The dipping lug rig makes a lot of sense, with its power and elegant
simplicity. Bolgers hypothesis, is that most everyday sailers today
use their motors to set course, so simple dipping lugs make good sense
in this modern era. If you need a bunch of small tacks to get through
a channel, use the motor. With a long straight course, use the
dipping lug.
