    Dyneema Rigging

    in TechTalk

    Posted

    There are performance and cost advantages, but seeing as people expect their standing rigging to last at least 10 - 15 years it is hard to imagine Dyneema lasting the distance and there is the chafe issue.

    There is also the question of whether an insurance company would cover a rigging failure if it was Dyneema.

    I suspect most would prefer to stick to tried and tested wire\rod or carbon for the well heeled.

    Oh no someone was wrong on the internet. :roll:

     

    I'll fix it for you.

     

    Feel bad for Gabart but only as much as one can feel bad for someone who gets paid to sail a f##ken big ass tri across the oceans.

     

    Better  ;-)

    Boris is doing well, went his own way and still got speed south, time will tell is he pays the price or not for hanging in the North. The Ultimes are getting interesting with 260m to go and Joyon only 50 miles behind Garbart and closing, he might run out of runway though as they are covering 600 miles plus per 24 hours. Both will smash the previous record.

    Backstay flicker

    Depends on the Roach of your Mainsail, of course the optimal length is long enough so the backstay doesn't snag. I have seen a few that use a carbon tube and a spring but can't see them working well on a high roach main. You could just get another batten and paint it  with awlwood to protect it from the UV.

    Yanmar

    You would think Harry that with Yanmar being used all over the joint their parts would be cheaper but no. Can't buy them from overseas either because agents in one country can't send to another. I noticed the Chinese are getting in on the act with parts coming up on Alixpress...but..but..would you trust them!!?

     

    These guys ship Yanmar parts worldwide.

     i'm sure there are many others.sure there are many others.

    Could blow up, but they have pretty good load sensors nowadays so he knows how hard he can push. Will be interesting to see how it plays out getting around the Azores high.

    They are doing about half that speed but, yes it is everything to do with the seaway. Listened to AT last skippers report and they are all slowing down to preserve the boats.

    The conclusion is boats have come a long way in 50 years. Solid heavy and slow is not safe in most conditions. Particularly heavy reaching and running the old school was to drag a load of sh*t out the back and slow the boat down as they were uncontrollable at speed. But if you can keep at or near the same speed as the waves on a modern boat they are a lot safer... unless of course you hit something :)

    Yanmar

    One consideration of a lot of "marine conversion" diesels is the timing gear. Modern day engines in cars use a cam belt. Not sure if all marine purpose built engines use gears but the Yanmar does. It's difficult enough doing a cam belt in a car but with most marine installations, it could be bloody nightmare and needs to be done on a regularly. Not so with gear driven cams.

    Pretty sure most marine/industrial engines are still OHV not OHC so are unlikely to have cam belts.
