Re: [bolger] Re: Building Update - Stretched Windsprint

Jon,

Did you consider bending the halyard on closer to the forward end of its
spar?

That's a good comparison. She's also got more freeboard than the
SHS, which is a good thing, I believe, since she's only decked on
the ends, and below the rail at that. There is a chunk of lead, but
only about 20 lbs. to keep the daggerboard down where it belongs. I
have considered making a heavier board if necessary after some
trials.

The plan is to use the same sail as the original and be a little
more relaxed in the gusty winds where we sail. On paper, the center
of sail area moves a couple of inches forward of the center of
lateral resistance in my scale-up, so I increased the rake of the
mast and the rudder size a bit to hopefully compensate. It is still
tempting, especially from a cost perspective, to fit one of the two
103 sq.ft. gaff sails from our Light (Cat) Schooner into this boat,
but I've always wanted to sail a lug.

She sounds (and looks) a lot like an SHS hull with a different
interior arrangement and no big chunk of lead. Do you also plan to
scale up the rig? Will she still be a single balanced lug?

Thanks for including all of the pictures, they are always a help
when building your own boat and wondering how something should be fit in
properly. Plus you did a very nice job and the finished product is well
worth showing off.

I've posted four new photos of my stretched Windsprint project. Recall
that on this boat I scaled up the side panels of the original by 25%
and left everything else the same. This results in a length of about
20'-4", due to the greater depth of the side panels (20" vs 16"), and
illustrates the difference between scaling and simply changing the
station spacing.

I was unable to reach my shop during February and March due to heavy
drifted snow, and the lost time means she might not get launched until
July or August, assuming all my other plans for this summer don't
intefere still more. She's due for floorboards and appendage work this
weekend. Further ahead are spars and rigging.
