    Did a ringframe carbon composite but set it up to take a really beefy fitting for the furler to attach to after the old one let go. It is inline with the headstay so the hardware bolts work in tension without the sheer loads of the old design. Very strong but I'll think about replacing the bolted fitting with a carbon attachment when it is time to replace the bolts.

    Peterchech.
    I heard you have a bit of a nasty coming your way.
    Perhaps you have taken Obama's advice and evacuated.
    However I hope you are OK.
    Please let us know how you get on.
    Good Luck. OS.

    JFWIW photo's of how we do it and it might help explain what Gary is saying a bit clearer.

    Thanks Outside, Gary's prose made sense but a picture is supposed to be worth 1000 words. Spreading the load over so much surface is quite different from conventional hardware concentrations. It is easy to see that the hull won't get a huge bulge with the carbon fanned out which I was having a time visualizing. Getting metal out of the boat saves weight and money. My new motto will be "Stainless ain't blameless" !

    chainplate details

    Thanks for those pics. Anybody else have any? I am still getting a sense of "how much" is enough. B

    A-boards update

    I have been trying out my a-boards instead of writing:D I am still undecided if they are worth the effort, and I do have pics to post but I am having pixel down sizing issues and they are not all that interesting anyway. The short answer is they have a lot of lift, but are a real problem to "tack" in short races. I also think mine may be too large and developing more lift and drag than my boat has sail area to use. I have not tried them in 15 knot plus conditions, but they seem to work better as the wind increases. It is quite possible to make a smaller set:cool: My lake is draining away due to drought conditions so I am just about out of testing time this year. I am going to use my floats for a small power cat this winter. I have the extra parts, a 15 hp engine, and too much time, so... I will post pics once I have worked thru the new camera issues. B

    I just saw ur hurricane message from august OS7. Belatedly, thanks! Fortunately, it wasn't so bad and all my tie downs held up fine.

    Bruce, I've always said that the FOIL THING can be overdone; they don't have to be large, in fact imo, they're better off being a little too small. The trick is to get the compromise correct, large enough to provide high, fast beating to windward plus enough lift to keep the lee float up. The faster you go, the more the lift. Therefore it is better to go small and deep but with the ability to lift the foils for differing conditions. Think of big keels on keel boats; too large, they drag horribly ... plus the boat trips over itself. You might have unintentionally drifted into that area.
    Certainly on Miranda there is absolutely no problem in tacking ability speed.
    You need to sail on a very wide tri foiler ... then you start to worry a little about tacking time - but it is still not a problem.

    board handing

    Gary, I think you are right and I probably have slightly too large of boards- they are very powerful, but that isn't really the issue for me. They lift and work! very well and the boat tacks fine, maybe a little slower but still very manageable. The crew and myself are not so quick:rolleyes:- and local races tend to be short windward/leewards, so we have trouble getting the boards up and down before/after tacks quickly enough. My first board came out a little thick and tends to stick some and that isn't helping either- but I will fix the trunk when the boat comes out for the winter. I am still early in the learning curve of using them to their best advantage, and I will probably build a smaller set some time this winter. They should fit well, move much easier, and should provide the proper amount of lift. I had to start somewhere:) B

    Bruce, have to start somewhere, absolutely.
    You could reduce the chord and area of your existing foils by cutting and reshaping ... and then bulking out a small amount the entry and exit areas of your cases with filler, shaping to fit the new foil profile ... and that would be a a fairly painless way of getting sailing again.

    I only have one more set of B24 plans. When they are gone there will be no more.
    Now that the US$ and AU$ are at par the price of this very last set of Buccaneer 24 plans is $150.00 shipped worldwide.

    Some new Buc board pics

    Gary, I have been out "testing", and I think the A-boards are great, but I did make them a little large. Mine are carbon over foam and can't be cut down, but they are pretty easy to build- and I will have a new smaller set for next season. These will work fine for cruising so they are not wasted. I made these about 72" long giving 40"x 11.5" under the floats. I think the same length and about an 8" cord will be about right, and also allow some angle of attack adjustment. I made these too close of a fit in the trunk:mad:. These boards provide enough vertical "lift" to almost keep the float out of the water at 5-7kts while providing plenty of lift to weather, but they also slow the boat down- there is always a lift to drag trade-off. The Buc "feels" great with them- it still tacks and jibes fine, (I even spent an hour with only a 90% jib, a bimini and no main and I could still tack through 105 degrees at around 5kts) and the boat balances well enough to track quite well with just bunge cords holding the tiller. The draft is only about 4' with the boards all the way down and a real advantage for shallow water compared to my center dagger at 6'. The boat also responds to puffs better and accelerates more instead of burying the float- quite a different feel. I still don't have good pics from outside the boat, but I will keep trying. B

    Great stuff Bruce.
    I am glad you are pleased with them. Perhaps it will encourage others to do likewise. :D
