    Anyone got any tricks for protecting it ( Eg. use mousing line attached to halyard shackle so that the Dyneema can be withdrawn into the mast when not in use ??

    Thanks to all
    Racers strip off the coat to reduce weight and windage, just leave the coat on, its purpose is to cover the core where the strength is.

    yea that was my point about keeping it covered ie the outer coating in place as a previous formite had mentioned stripped dynema.

    i have then had it hard racing for 6 years without problems

    Default Braid On Braid Is Good Enough

    I use braid on braid on my boat and have used braid on braid on a charter fleet as well. Adjusting the Halyard when sailing is pretty standard practice and upwind performance has never been limited because of braid on braid. It lasts years as well.

    I would recommend that you go for brain on braid.

    3 strand pre-stretched used to be the norm for cruising boats 30 yrs ago
    with wire to braid for racing

    I have bought from them in the past and had good service
    For regular racing use dyneema certainly, but for cruising a good polyester braid-on-braid with low stretch figures performs well and is much cheaper. My stock brand is 2.2% at 20% of break load, anything similar or better would be good. For halyards don't be tempted downsize for economy, you'll increase the stretch by about the sq of the difference in diameter.

    Main halyard needs replacing and am confused by conflicting advice from chandlers.

    Some say Liros braid on braid

    Others say low stretch polyester with braided outer

    What do people think ?
    Dyneema - my spinnaker halyard is 20 years old and still utterly sound (and that is in the Med).

    An alternative is Vectran - not quite as strong but slightly less stretch.

    For a main the size of yours (it's similar to mine) braid on braid, even is prestretched will be a very cheapskate and unsatisfactory solution.

    My original halyard was Kevlar - that does suffer from UV degradation as well as fatigue - its only advantage was its lack of stretch.

    If that is so can someone please explain how my customer with a Storm 33 rerigged his main halyard and all other running rigging with my brand of braid-on-braid and achieved 3rd in class round the Isle of Wight this year? I offered it for cruising rather than racing but he doesn't regard his purchase as "cheapskate".
    It would be more helpful if contributors could offer their advice from their own perspective whether cruising or racing.
