What is the diameter of your jib/gennaker sheets?
Genoa is 12mm double braid

Don, thanks for the rigging list. I’m curious as to the note in the rigging schedule:
The Topping Lift in Spectra is a non-standard and has been specked for #91 so that used in conjuction with the appropriate tension on the main sheet traveller it can be used to replicate a back stay tensioner. This is to reduce load on the rigging when sailing downwind or when motoring into headwinds or when sailing close-hauled. The Topping lift is normally supplied in YACHTMASTER XS.
Why would you need to do this when “motoring into headwinds or when sailing close-hauled”? I can see motoring into big seas, but just headwinds? And how do you remember to do this?
Not sure, this was sent be Grant. May want to ask him.
I’m not sure who owns #91, Tourterelles is #97 and Don is the hull before us so looks like an old comment left on the rigging schedule. Ann
It’s easy to remember to put the topping lift on… if the main sheet is loose when motoring, the wave action will cause the boom to flog. And if the topping lift is loose, then the boom will be riding on the vang. Both situations are obvious and uncomfortable. Our boom has the internal dinghy lift. If the boom doesn’t have a bit of angle to it, the boom extension doesn’t retract as well.
I got Sparcraft to change the topping lift on the 500SE from Yachtmaster braid to a Spectra core with a yachtmaster covdr so as to reduce the shock loads on the rig under when sailing without the main sail, which when sailing deep off the wind and especially downwind using the main adds no value and in fact the opposite is true if sailing short handed (which I think most of us do!!) when caught in a squall with a main up and a spinnaker. The dyneema or spectra topping lift (it does not require the cover to be dyneema ) acts like a monohull backstay if you center your traveller and sheet the main sheet in really tight, you will be surprised how the rig stress is relieved. One really notices this when the main is not set, for obvious reasons. I am build #91
