The above will give a total minimum weight on each leg of the sling of 2,000 pounds divided by 2 legs or . If they are not willing to take the financial risk, are you willing to risk yourself and your crew? In fact, I had sailed on an identical boat for a total of about 60,000 miles. A change of about 1.5cm that was well noticeable at a height of 20 meters. With a bent mast the first thing really is to understand was why it is so. But, the overall curve of the three sections of the mast was not yet regular. Does anyone know if 5/32" is the factory size? Imagine bearing away, removing the genoa and hoisting a large spi. This T-bone, if forgotten closed, supports the mast only at the level of spreaders, leaving the masthead free. Give us a call, and we can give you a rough quote. Certainly distributing the tension between runner and checkstay greatly reduces the load of the standing rigging. Heat stretching is a bit like work hardening so if the fiber is already work hardened then the heat stretching at the braided level does not produce the Densest braided structure that you can get if the Dyneema fiber is not heat stretched before braiding. We are Patreons of Rigging Doctor, the combination of their YouTube channel and website has more practical resources on real world cruising use of Dyneema than any other Ive found. It is your responsibility to assure that the slings you use are appropriate for your application. For 8mm stainless steel the breaking strength is 4640kg. Tightening the left runner-checkstay pair seemed more or less ok. Starboard we clearly had a problem, the mast would bend to windward at the height of the second set of spreaders. They show up on your doorstep ready to use. The influence of forestay-V1 and D1 on the bend of the mast up to the first spreader. Contrary to popular thought, a slack rig is more punishing on a hull than a properly adjusted, tight rig. Before Ordering Your Colligo Dux Rigging, lots of information and a range of Dyneema for standing rigging from different suppliers, Simplifying fitting a Jordan Series Drogue Sustainable Sailing, Dyneema / Synthetic Rigging Summary Sustainable Sailing, Dyneema Shroud and Chainplate progress Sustainable Sailing, Follow Sustainable Sailing on WordPress.com, DM20 (least creep, but also not as strong, most expensive), SK78 (the first Dyneema with reduced creep). There is no one-size-fits-all with running rigging. Get the full sizing and inventory of: - the standing rigging - the running rigging - the mast section with weight and size - gravity center localization - and mast tuning report 4. This is the same both on Mini 650s and on Class40s. All the vertical tension turned into compression and bend. Write down the number and move on to the next stay. In order to confidently specify a replacement for any element of your standing rigging, you will need to know what your existing components are called and how they are measured.Some end fittings have generic names e.g. I have an older Hallberg Rassy 35 (yep, thats the new challenge) - and currently the rigging appears to be 5/16" wire (that's what the local rigger measured, it seemed slightly smaller to me but he probably does a better job at measurment). The terminations for wire vs. rod can be quite different and require a lot of customization. ). iPhone. The wire is inserted into the hollow terminal and pulled through a set of roller dies. Running rigging - SailboatOwners.com He said it looked fine. This is not to say it was already set right, but we had zeroed the lateral tension errors. That is with the forestay and backstay attached to the masthead as fixed standing rigging that create traction in the opposite direction. We always look forward to seeing you! The picture below shows the most common rigging terminals used at Jimmy Green Marine.From left to right, Talurit Thimble Eye, Fixed Eye, Shackle Toggle, Stud, Stemball (Elephants foot), Toggle Fork, the toggle fork on the bottom of a rigging screw, Fixed Fork, Hamma Spoon, and Flat Head. One seemingly easy option is to over-size. For a -inch turnbuckle with a -inch toggle, the chainplate should be at least inch thick. Tensioning the backstay, the central part of the mast advances forward creating a slight C shape of the mast seen from the side. I jibed without runners in 50 knots of wind and nothing happened. Just select your boat below and you're a couple clicks away from new, top quality rigging. My personal opinion is that when offshore racing it is best to avoid easily avoidable risks. Chainplates 101: Inspect and Refit | Cruising World Make sure your turnbuckle is centered between the studs for accurate measurement. If your running rigging leads back to the cockpit, remember to account for that in your length. rope than a cruiser. Their role is to prevent the mast from bending to leeward between the first and second spreader levels, especially upwind. From the Rigger: First, if your old rope served its purpose but needs replacing, we recommend duplicating it as closely as possible Read more, http://rigworks.com/maintaining-your-standing-rigging/, http://rigworks.com/wp-content/uploads/2016/03/Standing-Rigging-Care.pdf, http://rigworks.com/the-scoop-on-rig-inspections/. Their sizing post is Sizing for Creep. As we go through the sizing calculations comparisons are difficult as they dont use the same version of Dyneema. Whats up? Rigging size | SailNet Community Since this boat is sailed in the Mediterranean we must have a good light wind setup and be able to intervene on the shape of the sail as the wind increases. So we measured the total length of the left and starboard turnbuckle system for both the vertical shrouds (V1) and the low diagonals (D1). Usually they are made with dyneema and not just simple polyester. For 6.5mm stainless steel the breaking strength is 3220kg. Also Marlow describes them all and includes comparison charts. The distance between the halyard and the mast at the boom is your rake. He asked Isnt the industry standard just a ploy by manufacturers to sell more wire. Still, as we will be doing the splicing ourselves, it isnt the end of the world if we need to shorten the shrouds once or twice in their life. Sort by: For example, many chainplates are too thin to grip clevis pins correctly. So I am going to be adding Hampidjan DynIce Dux into my calculations and it is cheaper than the LIROS D-Pro-XTR, plus available in more sizes. Taking the upper and a single lower of 5/16" gives a safety factor of 3.1. From Marlow Ropes we have this: Others refer to Elastic Stretch, Constructional Stretch and Creep.
