    Water stay tension

    Following on the theme from post #314.

    Are the water stays always in tension with the mast stays? What is the tension on the mast stays? I am getting ready to rig my new (old) B24 for the first time, any thoughts would be appreciated.

    Best,
    Carl

    If your waterstays are the SS flat bars as shown in the design, then they are not adjustable.(a good thing).
    Adjustment of the upper and lower forestays affects the tension on the mainstays, the angle of the mast, the bow in the mast (if any), the weather helm (if the mast is angled too far back), the set of the mainsail (if the mast is bowed forward or back).

    If your B24 has the simple tubular mast, then it is pretty stiff and is easy to "tune". If you have a more flexable mast with a teardrop section (like the mast from a racing Cat) then it gets complicated, especially if the mast has spreaders. Generally speaking, you will find that with enough wind the lee shroud is not under tension.
    However if all your shrouds are very tight at all times, then you are putting un-necessary loads on the structure of the boat.
    Yes -- it's complicated,--but not that bad.
    You just have to "Sort it out" yourself. :eek:

    hi, bought a b24 that needs some tlc (part rebuild).
    I have just signed up so sorry if i have missed and questions and answers.
    Samnz has built some good looking beams, are they lighter than the aluminium "pipes" or is the benefit in clearing the water?
    What materials did you use to build them?

    If you include the amount of SS removed theyre the same weight and much much stiffer.

    one thing the water stays dont help with is the down force on the floats, this is why they will be very floppy with the alloy tube and wire setup...

    stay set up

    I have a rotating teardrop section alloy mast (30' I, 36' overall) with side diamonds and single shrouds/stays to the floats. I have found about 400-500lb static load seems to give the best all round performance and keeps the boat from "flexing". The leeward stay just starts to go slack when the boat is loaded hard. I get much of my forestay tension from my main sheet, but it is nice to keep the forestay reasonably tight when I let the main out to de-power. It is probably not good for the hulls to leave that much tension on all the time, but I have done it for two seasons with out any ill effects. (I think) The Bucs that have adjustable stays like Capricorn and Miranda have the better set up, the mast can be canted some to weather, and it is easy to release the tension. Next season, I will have them also. Bruce

    Capricorn details

    Samnz, how were the mast step loads carried in Capricorn with the forward cantilever beam? Also, on a completely different question, how would/does your racing rating system handicap a Corsair 24/II compared to Capricorn? Bruce

    The mast step had a big bit of timber in between the cabintop and the top of the beam. The beam had reinforcing were the mast step support rested on it.

    Capricorn is sold now, however its rated at 1.0001 compaired to the fastest C24 (which has a taller mast and much bigger mainsail than standard) at 0.8478 so the Bucc is 15% faster....

    http://racetrack.org.nz/boat_ranking.php?s=1 Capricorn ranked 37th fastest boat in NZ

    Not if the main shroud is tensioned just sufficiently.
    Properly set up with the water stays and shrouds in tension and the tubular crossbeams in compression the system is in fact very rigid and strong.
    Lockie got it right. ;)

    Yes they are. Refer to above post.
    I have now fixed things so that the plans are permanently available, but to maintain personal security and privacy for both parties I will only communicate by Private Messaging.

    Thats just dandy, i need to post a few more messages - I live on the SE coast of England (UK) and never far from the sea, there is some good estuary and inlets to explore (some quite shallow), also a trip across the English Channel to France for a few days is nice in the summer, weather permitting, I do like old classic boats of any discription and the Buccaneer 24 suits my needs perfectly, can sail single handed, shallow draft and quite quick of the mark and she has a certain charm - i am without a boat at the moment, i have only sailed keel boats in the past and the largest boat i owned was a classic She 27 built by Sparkman & Stephens - really looking forward to building this old girl (Buccaneer 24) and of course sailing her.
