35ft Jeanneau Masthead, T piece set into mast for wire halyard leading down to the block. 12mm Dyneema for the mainsheet block.Thanks for the suggestion, I'd thought about this myself, obviously the low cost solution, but always wondered whether you'd be able to get sufficient tension with this method. You say 16:1 , what does that mean in practical terms of the mainsheet block,a double pulleytimes two? i'd be interested to know what size of boat you've and yhis works for you, tension wise. otherwise I'd assumed it'd be better to go for the wichard , seasure options.
Thanks for that,very interesting, assume the change to dyneema was for the non stretch characteristics? Is it practical stuff to handle through the mainsheet tackle and winch?Was there too much stretch with the standard braided stuff?35ft Jeanneau Masthead, T piece set into mast for wire halyard leading down to the block. 12mm Dyneema for the mainsheet block.
In theory, my coachroof winch pulls 450kg before slipping. Harken blocks, large. Times that by 16 and you have around 7.5 tonnes force. More, much more than enough. A Highfield lever gets nowhere near it.
Photos here, was in 2005 before I changed to Dyneema and block
I've made my own and then another for a friend who has a 34ft Jeanneau.Both have been used in anger several times.I'm pretty sure you can find a skilled welder willing to make you one for a whole lot less than the nearly £300 they cost.You'd have to provide the turnbuckle.thanks very much for the info, definitely more or lesss what I was looking for, just i think your model might be a wee bit on the small side, I have 7mm wire and forestay must be 40ft in lengthy. I see they do the larger , and more costly, model, probably what I'd need.
