For Bookie B. You sure do things the hard way. Do ALL
calculations
in metric and then convert to english units in the end. This
avoids the craziness of converting ounces to pounds and feet to
furlongs etc.

The 55% heavier I came up with is close enough to your 60% as makes
no odds, so I didn't screw up completely (or else we both did :-).

Yep, use Metric units all the time, esp. since even I can divide
and multiply by 10/100/1000 without too many mistakes.

In this group though, I think most readers are from the US,
and are more familiar with Imperial/US units, so that's what I try
and use.

OOOps, my metric tirade swhut down my brain. I mean 1 watt
=1Joule/sec and I meant Mt/FN.

Made my first sail. I am glad I used visqueen because the first
attempt was botched. Yielded a serviceable "back-up" sail but I will
make another.


LAUNCH OF #1 TOMMOROW.

SUCCESS!!!

Put her on the top of my truck (not a practical means of transport)
and hauled her to Shell Pt, FL, south of Tallahassee. Had 15 kts of
wind and rigging while in chop and wind was difficult but got it done.
Sail kept slipping down the gaff and boom so really had only about
2/3 sail but SHE FLIES. Tacks well, handles well, really great.
Slight prob is that the tiller keeps coming out of the box. Tiller
and rudder box seem a little wimpy as they were both bending under the
load. Christened her as "Tadpole" and she really swims. She does
sorta need coamings as water does come over the bow in chop but I had
a bailer handy.
My 13 yr old son took her out and had problems as he really didnt
understand "jibing" and turned her over twice. I found that standing
on the daggerboard will right her slowly. He eventually learned how to
jibe and to sail her through a tack and he was seriously impressed.
Got the sail adjusted better and my wife and I took her out and she
handles beautifully. Shell Pt has lots of oysters on the shore so she
did get a little banged up as expected but it was worth it.
She did get a little water in her fwd compartment somehow so I will
have to drill holes.
Carrying her to and from the water was a problem so I will have to
build a cart and I also need a trailer for her and #2
I am very impressed.

Thanks for sharing your build process. It's been a great post that I have
looked forward to reading.

When you get your pictures you might want to email them to Stevenson
Projects - they have a web site that they (eventually) will post them
to. And since the plans come from them, they like to hear about
successful launches.

Congratulations!
Gotta be some kind of speed record for the build too...

Enjoy!

BTW, I used the 1/8" wall X 2" OD material for the mast but used .050"
wall X 2" for the gaff and boom. Seems to work well.

Got transom installed on #2.

BTW, instead of using duct tape for my sail, I used the double sided
glass reinforced carpet tape at the seams. Since the adhesive surface
area is larger, it should hold better. I used single sided glass
reinforced carpet tape to reinforce high stress areas such as around
the pulleys on the boom.

Past two days of rain have really slowed down #2. I have no sheltered
area to work on them and was fortunate on #1 to have an historically
long period with no rain. Every day, I would have to wait till the
dew dried before working, now I have to wait till the rain dries but
now we will have regular afternoon showers, hmmmm.
Worked on #2 daggerboard.

Events seem to be conspiring to keep me from getting much done. Rain
every afternoon. A birthday party on Saturday, a block party on
Sunday. My wife in hospital for hysterectomy. I thought that when I
was not visiting her and not working or helping the kids, I could get
in a few minutes this afternoon. Instead, my 17 yr old daughter backs
over my wifes 15 yr old deaf and blind Golden Retriever. At first I
thought she had a broken back and was ready to do what had to be done
but tried to get her out from under the car with a sheet of ply.
Suddenly, she comes around, acts confused. Took her to vet and he
says she may be ok, amazing.
However, I did get the rudder and tiller for #2 cut out. Am having a
few probs with upper side stringers on #2. The sides were bowed so
much the stringer broke. I plan to glue the stringer back to correct
shape and have slit the side from top to bottom so I can bend the
edges to meet the stringer. I will have to glass this slit but thats
ok.
#1 (Tadpole) had a lot of use over Memorial day weekend and had a
little damage. I dropped her about 1' onto a concrete block and put a
gash in her bottom, a little glass and she is fixed.
No progress on the trailer yet.

Time to get on that mountain bike and go find some dirt - change of pace, kinda
thing...

I liked mountain biking but found that arthritis in my wrists and
elbows (aggravated by years of caving) made it difficult to hold the
handlebars through more than 15 minutes of rough trails. 48 yrs isnt
really not THAT old.
Unfortunately, the old Golden Retriever had to be "put down" as the
vet felt she would never recover due to being so old. Fortunately, my
wife had been released from the hospital so we sorta managed to have
her hobble into the vets office to say goodbye.
Managed to put some glue on upper stringers of #2. Began reinforcing
the rudder box of #1 by extending its sides to also better hold the
tiller so it cant jump out. It was easier to simply add another layer
of 1/4" ply to the upper part of the tiller box than to make another
box with thicker sides.
