Rand,
I've only launched it twice at the beach, once when it was howling but with very smooth water. The titanium pin is incredibly strong. See the entry several posts ago where I dropped the boat onto the pin and it skidded backward over the pavement on the end of the pin without bending. Nevertheless, given your experience I think I will order a spare pin. It shouldn't be a problem for Hawaii, since we launch from the dock:-)

Yes don't loose that pin :-) with the way you are doing things, I'd be less concerned with bending the pin, than with tweaking the carbon gudgeons, so pack extra carbon and epoxy too. :-)

Reminds me that I need to get some pins built, still barrow one from Gerry from the last trip to Hawaii!

The gudgeon reinforcement now complete, I have rough cut the G10 tube between the gudgeons. I've allowed space for a 1/8" G10 washer on each gudgeon. These will be fit over the G10 tube, and will carry the vertical forces from the foil. Once the washers are glued in, the G10 tubes will be ground flush with the washers.

I'm moving on to the tiller attachment. I have a carbon fiber tube left over from the rack struts that is a nice tight slip fit over the tiller. First I cut the angle on the rudder head. I just matched the angle on my spare rudder, which has been working fine. I then sealed the exposed core with epoxy. Next steps are to glue the tube onto the rudder head, provide appropriate epoxy fillets, and laminate carbon cloth over the tube and down onto the rudder.

This morning I glued on the tiller receiving tube and the G10 gudgeon washers. This evening I added generous thickened epoxy fillets between the receiving tube and the rudder head.

After sanding the fillets smooth and fair, I wrapped the tiller receiving tube with three layers of 200gm carbon cloth. These extended down onto the rudder head. I added a fourth layer over the joint itself, but not wrapped all the way over the tube.

I put the boat up on its side today and fit the rudder. I little grinding down of the G10 washers was required to let it fit over the bronze pintle carrier. I also ground down the aft end of the cassette or "book" that holds the bronze pintle carrier a bit to allow the rudder to swing freely. Here's a photo of the finished rudder head, less paint.

Steve; That is way to sexy looking for paint!! I vote clear coat.
Cheers

The boat is now back home from Hawaii. The new rudder performed admirably, however, the nut on the tiller needs adjusting :lol:
We managed to run into a reef during the Hawaiian State Championship pursuit race...with the spinnaker up...two wiring. Fortunately, we spotted sand ahead and turned down, so we had taken a little heat off, but we hit the coral going at least 10 kts. Also fortunately for us, we hit multiple heads before coming to a complete stop and capsizing, so it was not like we slammed into a wall. No immediate damage to the boat was apparent, but the over-built Waterat daggerboard was not looking too good (see photos). After floating off the reef, we righted the boat, pulled the daggerboard up so it was bearing on undamaged laminate and headed in. Once in we pulled the cassette and suprise, no damage to the boat or the cassette. Kris Henderson happened to have a new daggerboard available for purchase, so a little work on both the cassette and carbon plate on the bottom of the boat to get them to accept the different foil section, and we were good to go. The boat is still leak free.

At the time, we had passed the eventual 4th place finisher, were bearing down hard on the 3rd place boat and were still way ahead of the eventual winner and second place boat. That was par for the course for our regatta, but sailing includes navigating too. The Exxon Valdez was almost safely in port when they hit a reef...

Now I need to make a new cassette that properly fits the new board, and of course, repair my "spare" daggerboard.

I'm definitely taking my time with the repair, since I'm happy to be using my new Hendo centerboard. Here's a few photos showing the extent I've had to grind out damaged material. I still have a ways to go before I'm happy that the remaining material is solid.

I've finally given up on the forward position for the jib cleat. I know a few like it up there, but I've decided to move it back to a position 3 feet forward of the transom, which seems the current most-popular position. I'm using a simplified variation on the excellent jib cleat system that Hendo makes. This one just has a post with the jibsheet led up the inside from a thru-deck block installed in the side of the post (same basic idea as Hendo's). However, instead of taking a standard Harken swivel cam base, drilling a hole through the base and fabricating a carbon fiber housing for a second through-deck block, I'm using Harken's dou-cam swivel base. This is pricey, but it has the top turning block already built in. I will cut off the extra cam cleat and arm with a hacksaw. If we could just get Harken to make a single cam swivel base with the top turning block, I'm sure it would be cheaper, and a bit lighter to boot. Maybe Hendo and some of the Seattle fleet have the connections to get Harken to consider this.

The post is now structurally complete. It now remains to paint and fasten the hardware.

A 5/16 inch G10 plate was added at the joint between the post and kick bar, to provide some meat to drill and tap for the turning block's lower screw. After providing generous thickened epoxy fillets all around at the joint between post and kickbar, as well as around the G10 plate, I covered the joint with 2 to 3 layers of carbon fiber tabbing, again cut at 45/45 from 200 gm cloth. The whole lot was sanded this morning and coated with clear epoxy. I'm sailing tomorrow at the San Diego One-Design Weekend, so I will hit this with the heat gun tonight to try and get rid of any residual stickyness before screwing on the hardware.

Shu:

Funny, I am working on a similar fitting. How are you going to modify the swivel cleat to take a block leading the sheet through the center hole?

Ed & Matt,
These photos should clarify it for you. The Harken Dou-Cam is intended to provide two lines to the same location, most likely a mainsheet from above and some other adjustment line (like a backstay?) up through the center from below. I'm using the integral up-through-the-center-from-below feed and turning block along with the upper main cam cleat. I intend to cut off the lower cam cleat and drill out the strap shackle and extra sheeve, as well as generally smooth and clean up the aluminum frame. I had the boat out this weekend and was quite pleased with it. Tacking is very easy, and it works so easily I find I can trim the jib in and out as much as I want. That's a huge change from grunting it in after a tack and then not touching it until the next tack, as I was doing before.

The only disadvantage I found was gybing while I was crewing, I kept whacking it with my heel as I tried to step across the boat, which would stop me cold on the old windward side and result in me grovelling on my knees to get to the new windward side before the boat came over on top of me. I'm sure I just have to change my footwork a bit and I'll be fine, or maybe I should just stay back in the cushy helm position. All things considered, It's a great addition to the boat.
