NZTiger 17 Posted May 6, 2019 Share Posted May 6, 2019 Both the inner and outer shrouds on my GBE connect to the same point on the hull. The inner shroud connects to the mast about 75% of the way to the top and the outer shroud goes almost to the top. From what I can tell, the inner shroud is standard on a GBE and there was no outer shroud on the original design. I'm guessing the outer ones were added to support larger downwind sails. My outer shroud connection appears to be less than ideal and needs sorting. (Pictures attached). Note that the current arrangement has a wire rope ending about 2m from the connection point and 6mm braid between that point and the hull connection. My questions are: What is the ideal method of connection/setup? Should I be able to tension them? (they are both essentially slack at present). How important are these things?

Clipper 343 Posted May 6, 2019 Share Posted May 6, 2019 On Voom and Freedom the topmast sidestays are adjustable. Essentially off all the time unless running masthead kites, then they are probably critical. The braid doesn't look up to the job to me. They should be slack unless needed, so some way of tensioning is needed. Quote Link to post Share on other sites
Ex Machina 365 Posted May 6, 2019 Share Posted May 6, 2019 I use to sail one with similar setup to that but the braid went through a double purchase block with cleat very similar to what is on some trapeze wires . We would only tension the windward one when flying assymetrics and just enough to take slack out of the shroud . The block was tied off to the chain plate and from memory it was at about eye level when sitting in cockpit so forward crew could reach it easily. That boat was from the very far north too where I think yours was based ? So was probably set up the same Quote Link to post Share on other sites
TimB 7 Posted May 6, 2019 Share Posted May 6, 2019 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 Quote Link to post Share on other sites
Ed 143 Posted May 6, 2019 Share Posted May 6, 2019 The top mast side stays also come into play when you start running bigger square head mains upwind and close reaching. A bit of adjustment is good to keep the mast straight, especially with the older smaller sections. They do see a bit of load, if I remember correctly we had 12:1 purchase, but this was achieved with two cascades and a 3:! purchase. The leeward shroud will always be slack, not much can be done about that on GBE. Quote Link to post Share on other sites
Freedom GBE 27 Posted May 6, 2019 Share Posted May 6, 2019 Only need our outer stay for mast head kite and code 0, we have a mast head runner as well. We like to keep the mast straight. Seldom use fractional kite. Quote Link to post Share on other sites
NZTiger 17 Posted May 6, 2019 Author Share Posted May 6, 2019 Ok, thanks. It's looking like a becket block + cleat on the bottom and a block at the top. Time to go shopping. Quote Link to post Share on other sites
Adrianp 120 Posted May 6, 2019 Share Posted May 6, 2019 Not the greatest photos but kind of show the Freedom setup. We lost a mast through not having a reliable topmast backstay and sidestay setup so it is pretty important to get right if your going to use masthead gear. Quote Link to post Share on other sites
philstar 61 Posted May 7, 2019 Share Posted May 7, 2019 Nice to see you working on my boat adrian Yes freedom has a really good set up. Let the top mast side stay off upwind to allow the mast to flick off and depower. Crank it on a bit downwind to keep the mast straight. Quote Link to post Share on other sites
