    speed

    Our faster F24s haven't been out since I put my buc back in the water. Our best sailing season is just starting, I hope I am able to sail to the boat's potential. Bruce

    mast section

    I measured my mast section- Aprox 6.25" x 3.7" "teardrop" shape. The base, mast and masthead are stock Stiletto-27 cat parts that rotate on a 2" ball. My mast is 36' overall with the forestay/shroud tang about 6.5' from the top. It has diamond stays and spreaders. I don't know the the section weight but the whole mast, halyards and 3/16" shrouds (wire) weighs around 80 lbs. The mast is quite stiff, probably more than would be required if built to the stock Buc 24 specs. I think the 3/16" shrouds (stock buc 24 size) are marginal for the mast and sail area I have and the closed barrel 5/16" turnbuckles are definitely not up to the job- I will replace it all this winter. I don't have running backstays but will probably add them for the large reacher and some redundancy. Bruce

    Thank's for the information Bruce. It looks as if you have approximately the same weight per foot as the stock design does.
    I know that this thread is about the Buccaneer 24 but after the discussions about ama's being driven under I thought I would send this picture that I ran across showing just how far that can go. Supposedly the boat recovered from this and continued the race. I can imagine the crew needed a couple of stiff drinks to recover themselves.

    bruceb,
    here's some great info in synthetic shrouds, etc. I converted my Twiggy to SK-75 and lost a ton of weight in the rig. jmolin's rerig of his Searunner shows lots of other ways to replace metal with synthetics. I really like the soft hanks and soft halyard shackles.

    Hope to see your Buc 24 one day,

    synthetic

    I agree, I think synthetic is the way to go, it has reached the stage of development and price that it belongs on many boats, including most all multis. I know I will use it for my runners, and I might use it for my shrouds. I do have a lot of wire that I hope someone can use:?:, and a couple of roll swedge machines to go with it:) Bruce

    shrouds

    I weighed my 30' shrouds- 3/16 with an eye and a stud- 2.5lbs each plus the 1/2 lb turnbuckle. I think I am going to use stainless again, the weight saving and price seem to favor wire. (I have plenty of wire) The cost/benefit might be better in a few more years, right now, synthetic still has durability issues, particularly in small sizes. Bruce

    do you think 3/16 wire is strong enough? I have 1/4 inch wire on my forestay and sidestays, 3/16 on the topmasts, and 3/16 dynex on the mast head runners. 5mm on the diamond stays. I dont know what 5mm is in metric, in between 3/16 and 1/4...
    if you sail with all crew on windward float the loads skyrocket on the rig, im not sure Crowther invisioned this!

    I'm sure he didn't either.
    In the 1960s and '70s, NO ONE envisioned taller masts, fathead mylar mains, "prodders" with huge foresails and reaching spinnakers.
    The huge sail areas you use on yor B24 would have blown Lockies mind.
    (Come to think of it, we had mylar sails on our Piver Nugget in 1964. Fad didn't last tho'). LOL. :D

    big wire

    Samnz, I think you have the right size wire- 3/16 has a min breaking load of about 3700 lbs and a much lower working load- probably fine on the stock boat. I haven't been loading my boat up this season but I had better plan for the future and use the 1/4" wire. Do you have two sets of shrouds? ( uppers? "3/16" topmast") - I only have one set of shrouds, and diamonds on the mast. I am set up for runners but I haven't installed them yet. Thanks for reading my post, it might help keep my mast "up".

    I have argued with many people about this, and still think only higher righting moment can add load to a boat, not more sail area. More sail area just gets the the maximum load quicker, more righting moment actually adds to the maximum load on the rig and hulls/ beams?
    More righting moment gained by positioning crew and helmsman on the floats...

    rig load

    Samnz, That is a good picture:cool: That looks like about a 1000 lbs (no offense to your friends):) and you still have some reserve. I think you are correct, the righting moment does limit the rig loads, but with the speed tri's can hit, shock loads and momentary gust loading can probably double the rig loads. I think my mast section is stiffer than yours, I don't know if that is good or bad. It doesn't go out of column as easily, but it doesn't de-power as quickly either. How do you adjust your side stays? Bruce
