    Passage records

    Well that didn't prompt anything, not even the obvious 9 hours to Te Kouma for Sundreamer, it was actually more like 2 hours. I though Puff might have jumped on that. Tb

    Passage records

    The NZMYC used to keep track of these because it mattered to them. Long time since I was involved but we used to have records for the two courses mentioned by waikore plus round waiheke, The Balokovic, the triangle that went round the islands off Te kouma, flat rock and back. Akl to Tauranga etc. Sundreamer once held the te kouma record at around 9 hours, i think, Afterburner had most of the others. This is before Vodafone/Frank racing appeared on the scene. Since then the idea seems to have kind of died, no competition i guess. Maybe this will prompt some memories from someone??? Cheers tb
  3. Should be less solid water over boat when flying/foiling if that is what this new boats is supposed to do. Still has drag several tonnes of lead with them so not so easy to fly. tb
  4. I wonder how the proposed new tug will be delivered from it's Asian manufacturer to Auckland? On it's own bottom? I doubt it. It won't get far in 4 hours...... Tb
  5. Dont know about anti foul but I believe the anodes will "settle down". You will have to replace them early, maybe 6 months, first time then the residual currents all find their happy places. No idea idea why technically, just know from experience. Tb
  6. and another point is that the mast and rigging on a yacht provides a helluva lot of windage, you will motor a whole lot faster for the same revs without the rig standing up, ie assuming you are trying to get somewhere after dropping the mast. Only problem is a yacht will be bloody uncomfortable without the roll slowing affect of the masts inertia.... unless it is a catamaran. No cats (or tris) in RNI unfortunately, but that is another thread topic Tb

    NRC on fan worm

    Today from Marlborough Council. I wonder if they apply this to the fishing fleet and the log ships coming into Shakespeare.... I doubt it. Marlborough Marinas Visitor Ruling May 2019.pdf Tb
  8. "Upwind would be damn near possible to point" Surely that is meant to be IMpossible? tb
  9. I would have thought the topmast runner would better a better support for the mast if it attached to the rear beam perhaps in line with the inside of the cockpit. the gennakers pull forwards as much as sideways. It would need a tweaker to pull it forward it out of the way when not in use though so much more complicated. Tb
  10. NZtiger, its a breakage issue..... when the main is reefed to or past the second reef the rig becomes a "masthead with no lowers". So the middle of the mast is unsupported (backwards) and can easily invert, pop backwards and in the extreme break. the temporary inner forestay stops this. it also stops the mast from bowing back which increases the mainsail draft, which you don't want when reefed this far. flat as possible is best. cheers tb

    Forestay cleat

    Cep, The flying Dutchman worlds are in Nelson right now, so there is 40 odd FD's there right now.. Have a look at their set up. They run the jib on a separate wire to the forestay and adjust the tension lots during the race, ie tighten up for up wind and slacken it right off down wind. Most of the guys are pretty keen to talk about their boats.. cheers Tb
  12. And vertical not angled out on a leaner???
  13. Hi Randii, In the early days some mast extrusions (which is what your beams are) were made in two pieces because the Aluminium company didn't have the capacity for larger dies. So they made some sections in two pieces with a stepped edge so they could be sort of clipped together, then riveted. Later the masts were made in one piece. Some really big ones were still made that way until recently. They are almost all carbon fibre nowadays. Tb
  14. Randii, the accepted method for making the sleeves is to buy the same section extrusion as the beam. The alloy beams on most tenant cats were typical mast sections of the appropriate size. You cut the bolt rope groove out. This allows you to compress it slightly and slide it into the beam. Usually riveted in place. some glue them as well. Also you need to round off the ends so they do not form a hard point where they finish. . Tb
  15. Why is the font so small?
