Re: [bolger] Re: Twist in Seagull hull
Last year I built a Wharram Tiki 26 catamaran, another stitch-and-glue
boat. The job of getting everything in line required drilling some holes
in permanent frames for passing longitudinal threads (a solution not
contained in the instructions), making holes in the ground for anchoring
strongpoints, laying stretching - members across the hulls at various
points, applying a lot of spanish windlasses and it took about one week to
get both hulls reasonably accurate, much longer than it would have taken
to build a strongback. Never again.

This was also my first stitch and glue boat. The other were Bolger
tack (or in my case drywall screw) and glue types. I found the stich
up method fascinating (I used nylon pull ties, at first loose than
pulled tight as all looked good) as a boats suddenly appeared out of
flopping, dancing side panels.
All my Bolger's came out fine, as the frames you're screwing to,
combined with building om a flat surface, act similar to building on
a strong back anyway. I guess the reason I'm not bnuilding on a real
SB is that none of the plans I've ordered call for one, or give any
offsets to make one to.
I'm just going to sand down the high side of the transom to visually
match the other and finish the boat. As one person said on another
group, 99% of the viewers will see nothing wrong, and the 1% who
notice are fellow builders who will understand and be too polite to
point it out.

With all respect to you Bruce, and regretably in no way solving your
problem, this is as good an example you could get, showing
that "instant boats" are a second rate building method, compared
with building on a temporary frame. I have never been able to
understand how this method has taken over from a building frame,
which is cheap, simple, relatively quick and above all accurate.
Anyone who can tackle a boat can easily build a frame.

Just finished taping all the external seams on the Seagull. This is
the first time I've seen her upside down. Looking from the bow all
seems nice and straight. When you sight along the bottom from the
transom, there it is, a noticable canting of the bottom. It looks
pretty close to 1/2" lower at the starboard side of the transom than
the port. Explecatives deleted.
Any suggestions?

Can't be that!

Got the doubled outwales bent on to finish 1 1/2" by 1 1/2". Rounded
them off at the transom corners, made a masking tape dam where they
joined at the bow and poured an epoxy slurry in to fill the cracks.
Needed because of my incredible carpentry skills. I'll round them off
and plane them flush to accept the breasthook. Should be turning to
goopazixe and tape the seams from the exterior today.
The twist at the stern jumps out to my eye. Onlookers barely see it,
but I think she's 1/2 inch high on the port side. I'll plane the top
of the transom down a bit to hide it from the eye. Will this affect
handling much? In effect the bottom is not flat at the stern, but
canted to starboard by that half inch twist. Shoul I allign the skeg
slightly to the lefgt to compensate, or will it not be too
noticeable. Will she go hard a starboard on every glide? Any
suggestions?
Took a few shots yesterday, actually put some film in the camera this
time. I'll post them when I finsih the roll.
Heading for Mexico City and San Diego by car next Wed. to get out of
this freeking snow for a while. She'll sit under a tarp till I return.
