  1. My 930 mast stays up due to one of those very saddles and 2 small rivets, which have to be weaker than weld.

     

    But I know what he means, things do suddenly look way to small when you look up and it is proportional to the amount hanging off it.

    As one of the blokes with an aversion to swimming, I think the saddle looks too small

  2. Thanks KM but the skipper/owner/bloke who must be happy even though he never uses the trapeze thinks that the welded eye isn't up to the job of keeping four blokes from going swimming.

     

    At this stage my thoughts are to use 6mm as suggested by ed, wrap this around the tee fitting similar to the vang wrapping around a carbon boom. First time round goes through the welded eye, second rests above the welded eye (I think there is enough room between the mast and tee fitting), repeat going back down, then half hitch both ends around the tee fitting to eliminate movement and finish with a splice.

     

    I might do a mock up and post a photo... See below

  3. Try and get a SK78, tad more strength and less stretch. A DM20 would be even better but that could be hard to find in most places still.

     

    Dynice is old school now so a lower grade.... but it will still work.

    Possibly restricted to what the yacht club has in stock and for trapeze line stretch isn't really a problem... Fitting into the trapeze harness and acting like a 20 year old is more concerning (turning 49 next month and the body isn't as flexible as it once was)

     

    Main concern is the knot/splice required at the hounds but hopefully Ed can take a photo of the detail tomorrow

  4. Use 6 mm dynice ( nee dynex) for the connection tee ball to jesus ring. Luggage tag to the ring and the tee ball before inserting into the mast

    Thanks Ed

     

    I think I have my head around this...

     

    Luggage tag around the tee ball end, using the welded half shackle to stop it from sliding down?

  5. This weeks entertainment is replacing the 8 trapeze lines on a Magic 25

     

    The mast was lowered today and I had my first look at the existing lines. All four trapeze lines connect to a ring with one short line connecting everything to the mast.

     

    So...

    New trapeze lines are easy enough to splice, using 4mm dyneema.

    Should they be luggage tagged to the ring?

     

    The short length connecting to the mast is currently a bit of a mess. It is held to the T-ball shroud end with a welded half shackle and multiple turns/knots/loops... Scissors were involved in the removal!

     

    Any tips would be appreciated as I will be hanging off the new lines in a couple of weeks and I don't like swimming

  6. Have seen some small race cats in europe where the tramp has a line running around the whole outside, and basically hung just from the four corners. Am thinking something similar with zips over the pod hatches.

    Have got preliminary design work for trailer which allows loading of boat fully rigged, then folds in for trailing. Suspension design was a head scratcher as hulls need to lift over wheels in the folding process.

    Luckily I had a bit of downtime at work, so out with the pencils!

    Transoms to the front of trailer?

  7. I recently had to have a windscreen replaced in the car... Cracked vertically right in front of the driver

     

    Call to insurance... "Call company XYZ and arrange a time"

     

    Call to company XYZ booking centre... "We can fit your windscreen in two weeks time, we are flat out, someone has been breaking every windscreen in the street with a hammer"

     

    After two weeks of driving the other car, the day arrives and the technician apologises for the delay as "the company makes us take holidays at this time of year so we are a bit behind"

     

    Holidays I can understand... Telling porkies to explain the delay is not a good look.

  8. Erice... Not following your point about the hiking loads from the crew, how is this affected by the removal of the traveller?

     

    Bridle on the transom, lead forward along the boom and sheet from the boom might work better than across the floor.

     

    If extra strength is required perhaps glass in an angled wooden brace between the side tanks and the floor.
