Kris sent us a laminate schedule which I hope we followed!

We set up a jig to hold everything and be able to square up everything. First the table was leveled. Now we had asurface from which to measure. We match cut two pieces of 2X6 and made sure the ends were square. So, when the 2x6s were put on the table we knew that all sides were vertical. Next a profile of the rudder cross section (airfoil) was cut into the 2x6s with the center line of the profile exctly vertical and the leading edge horizontal. Now we had a horizontal and vertical reference. With the 'T' foil in place in the notch in the rudder we measured down from the tips of the 'T' foil to the table and adjusted it until the measurement wa the same. Making the tips equal distance from the rudder head made sure the foil was perpendicular to the rudder. We applied a bead of fairing & adhesive mixed into epoxy around the joint, checked the measurements and let it set over night. The next day we applied the carbon cloth per Kris's schedule. This shows the jig with the foil in place.

It looks and measures square!

So, on Tuesday all that was left was to sand a couple of bumps off the rudder head to get it to fit into the casset. Well it slid in from the bottom then stuck. We had never slid it in this way before. It was always from the top and it was a little tight. So, we spent some time cutting away the back of the cassett untikl the rudder slid in smoothly. We dirlled a 3/8s hole for a pin to hold the rudder. Hopefully Thurdays we will try it out!

Looks Great guys! did we make it out for a sail ? The foil looks like it made it in the right spot, now just a little fairing and sanding.
Does the foil have any angle up?

Here is the almost final installation showing the 'Book', bronze piece and controls:

We sailed last week in under 8kts and very shifty. The effect of the foil is admaizing! The boat seem to plane at lower speeds and hold the plane longer as the breeze drops. You can definately feel the bow pitch up and down as the controls are moved.

We still have some bugs to work out. For one I seem to always be sitting on the controls at that wind speed.

We are very please with how far we have come. Hopefully we can sail in some races starting in August, perhaps Newport?

Next projects (probably winter work) are jibber & more bulbious bow.

Nice work guys.

Kingston is where you want to bring your boat for some epic sailing this August. I14s are having a start at CORK (site of the '72 Olympics) from August 20-22. We should be sharing a course with the 49ers and 29ers whom will be having their North Americans, so the skiffy vibe will be awesome. Fresh water, a strong sea-breeze and 20+ I14s, what more could we ask for?

about your bugs to workout, if your sitting on the controlls, don't sail in light air.
and your next project? forget a jyber or a bulb bow, it's time to SAIL!!! make sure all your controls work in all conditions,
and SAIL!! get some good footstraps for the back of the bus and hang on.

I agree with Kris, sail, sail, sail. You will be so much faster with time on the water than any modifications you can make to your hull shape.

Not sure a bulbous bow would be an improvement for an ICE. For the bulb not to slow the boat down (a distinct possibility), it would have to be tapered way back onto the hull, maybe 1/3 the distance to the transom or more. I agree with Rand and Kris, sailing the boat is what you need to do. Modifications to the hull shape are best accomplished during initial construction of the hull.

The pictures appear to show some forward lean to the bronze pintle carrier. Not sure if you redid the "book" attachment, or if you have a different geometry for the bronze piece, but that should help keep you out of trouble when things get exciting.

Matt & I have been sailing quite a lot this summer. Too busy to post and we haven't made any more changes. Everything seems to work except us and that's more me than Matt. I still look like I am hanging on to the trap wire for dear life!

I built a practice jib and what a difference it makes. We are faster through the tacks and comeout accelerating.

That's an awfully sexy looking jib. Not sure why you would want to relegate it only to practice if it is improving your boat's performance.

Matt & I sailed to day in about 15-20 kts. Now I know what you guys are talking about. These are incredible boats! Henderson's foil works really well. The POD and book held together. Even my jib didn't fall apart. While we were too busy surviving to appreciate fully the boat, it is still incredible! On to the Worlds!

Ok, realistically, we have a long way to go! We just survived. Probably would not have been able to right the boat if we had flipped and we were not racing. No chute just very close reaching. It was very puffy and 30 degree wind shifts. Matt did a great job with the main and keeping the boat up right. Ok, I still look like I am hanging on to the trap line for dear life, but, my grip is not as tight as it used to be! Matt said if we had double trapped we would have been a whole lot faster. The wind was pretty tricky. We probably are ready for some coaching!

We did put in a 1' reef. We are not experienced enough to really comment on this.

Oak Cliff Sailing had a Classic race and we went buy them in the opposite direction (close reaching) to whoops and hollers. We were too busy to even wave!

Hey Ed, it sounds like you guys are doing it. And doing it with a lot of the gear you built yourself. Congratulations. Close reaching in 15-20 kts and 30-degree shifts with no capsizes; that's some pretty good surviving you did there.

It was a couple of years before I could get through a jibe without capsizing in 25 knots (after I learned to ease the vang downwind…). Sail and enjoy!

Get to Richmond Y.C. before Saturday at 9 and we'll take you to Hawaii with us :-)

The old 1112 looks great, that thing will be a rocketship with a foil. Will love flat water and with that stiff rig it is perfectly set up to put a fat head main in it. The jib looks good. Keep sailing it hard. As Rand said, if you leave now you can easily make it to Richmond YC by Sat AM. You'd learn more about how to sail that boat in 1 wk with the fleet than a year by yourself. Great job! Keep it up

We are off to the American HPDOs. We are the only I14, so, we are sailing in the Portsmouth fleet with 3 Moths and a Hobie Trifoiler. The rating spread is 75 to 107. Goals - Finish all the races, have fun, meet some of the 49ers & Moth guys/girls. We have a 47' mother ship.

Hope you guys have fun in Hawaii!
