Re:Modify a Windsprint?
I appreciate your concerns. Windsprint is really a very small boat.
The pointy ends, though beautiful, make LOA deciptive, add no bouyancy,
and constrain interior space. Before I built I strongly considered a
stretched punt. After being out a few times, I wished I had done that
or scaled the design to 18'. Oh well. I'm pleased overall. And she
IS a beautiful boat.
I have not had a knockdown, but then I didn't go with the balance lug
as designed, which may make a difference. I've got sketches for my
sprit-boomed sprit sail in bolger2\files\windsprint stuff. The foot of
the sail is angled up, so I think I would sink the gunwale before I had
a knockdown on any point of sailing. Or maybe I'm chicken. Maybe this
summer, with warm water, all flotation, and my bailing bucket, I'll see
how far I can press it.
(Patrick: nice kayak! I've thought of building one next. Wait, Chris,
why don't you just leapfrog the Windsprint, build a CLC kayak, and get
the CLC outrigger and sea kayak sail kit. If you want to sprint on the
wind, I think that may be your best bet. Or a hobie cat. Or an ice

Lots of people make water-tight compartments fore and aft for flotation,
and therefore deck over the bow and stern. I put a deck about 4" below
the gunwales forward (back to the mast step), making a place where I was
comfortable letting my daughter lounge from the time she was 4. Now that
she's 13, she kind of hangs over the edges when she lounges up there,
but it is still where she goes when she is not steering. I made an
after-deck from the rear thwart back, about 2" below the gunwales. I
throw stuff back there to get it out of the way -- water bottles,
cushions, stern painter, etc. I haven't yet bothered with the
water-tight compartment thing, I just stacked up some closed cell foam
and put plywood on top of that. Someday, I'll finish the boat.
Windsprint was specifically designed to fit into 4 sheets of plywood. If
you add freeboard, you'll have to buy another sheet. I don't think it
will be quite as pretty. OTOH, another 2 inches might have saved me from
a capsize last July 4th. Or not. I think that I have capsized more often
from dragging the boom in the water (close reaching) than from excessive
heel. Truly, the boat feels safest to me when close-hauled.
I have needed to strengthen the rudder stock, reinforce the daggerboard
trunk where it attaches to the side of the boat, and repair the mast
step when the mast chewed it up -- not sure if that was during a capsize
or when we broke the rudder and were flopping around in large waves with
a fair bit of wind (and a ferry waiting for us to get out of the way).
Some photos of my boat are in the photos section of the Bolger group:
and some others are at: http://www.patrickcrockett.com/boats/boats.html
One photo on the latter page looks like the gunwale is perilously close
to the water, but I'm pretty sure we didn't ship any water that trip. My
daughter was OK with tippy-ness at that age, but would have been pretty
worried about water coming in. Part of what makes it look perilous is
the fact that the bow wave lifts up almost to the gunwale -- note that
at the ends the water is not so tall.
BTW, when you buy (or build) a sail, be _sure_ to have the second reef
put in -- if you single-hand the boat in any breeze at all, you will be
glad to have it. And figure out a way to reef the sail while under way.
I also found that a 2-part sheet was very helpful (and an over-sized one
-- I have 1/2" soft yacht braid). I tie off to the rudder stock, run the
sheet to the end of the boom, along the boom, and back to my hand from a
block at mid-boom. Much more comfortable when the wind pipes up than the
designed 1-part sheet (end of the boom to the rudder to the hand).

as you would then be into a six sheet boat have you thought of other
instants of around that size, eg COLD-WATER SAILBOARD, or JINNI?
Freeboard not greatly increased, but bottom beam is, so with transom
sterns these should stand up more to sail, and both have their own way
for easy recovery should capsise ever [guaranteed ;-)] happen. The
WINDSPRINT sail could be fitted to either with a little fiddling, if
