I am about to re-rig my Lotus 9.2. It is a strong and simple rig being single spreader, non tapered mast with fore and aft lowers, cap shrouds, forestay and backstay with effective tensioner.
I have taken the furler off not to be refitted this time around.
The question is about halyards. I am thinking 12 mm quality double braid for all halyards and whether halyard knots for attaching halyard shackles would be advisable. If I cut the ends off say every 12 months and moved the knots up onto fresh line, that should avoid failure of the attachments wouldn't it??
The yacht will be doing local club racing (only for the sake of using the boat regularly) and cruising from Bundaberg down the Great Sandy Straits and up to the Keppels and maybe the Whitsundays.
All opinions welcome.
Edit:- The rig is 11.5 metres tall.
Hi there, my name is Drew Van Ryn and run a small independent rigging company in the South of Sydney called Wet Tech Rigging.
12mm Polyester would be on the large side for a boat your size, but if you were considering knotting rather than splicing then the strength losses associated with the knot would bring you down towards the spliced strength of 10mm Polyester. If you went with spliced ends, 10mm Polyester would be fine. If you went with Dyneema-cored line you could get away with 10mm for your main halyard and 8mm for your headsail/spinnaker halyards - of course depending on whether your clutches could handle the smaller diameters.
There are plenty of options out there now days to avoid chafe, including utilising Dyneema Chafe Sleeve tips, which reduces diameter, maintains flexibility at the base of the splice and prevents chafe long-term - solving a number of concerns raised in this thread in relation to spliced ends being too bulky.
The benefits of Dyneema-cored lines over Polyester for stretch and strength has been brought up and correctly covered a number of times here already - if you're primarily cruising or your sails are Dacron construction, Polyester is fine. If you race the boat, or your sails are constructed from more exotic low-stretch materials, Dyneema or Vectran cores will extract the full potential out of your gear.
If yourself or anybody else in this thread would like any more information or to get some pricing for your options feel free to give me a call, send me an email or send an enquiry through my website - all my details can be found at
