For years ive had a jib furling "thing" but never used it.Now i would like to roll my jib away on my folkboat.
I posted ages ago about a system to roll the jib in or have it out nothing in between. And the wickham martin was sugested as was a harkan system! I have a stainless drum for the bottem and can buy a swivel for the top.(harken)
How do i attach the sail to the rolling forstay??That it rolls and unrolls??If i hank it on the hanks wount grip the turning forstay and if fixed top and bottem wouldent just the bottem roll up untill it jamed???
I must be the only person in the whole world thats never has any kind of forsail rolling system not even on my dingy!!!!!
How do the old ones without a foil work??

With Wickham Martin furling you need a wire rope, with a hard eye on each end, sewn on the luff of the sail. The WM turns the lower end of the luff and relies on the stiffness of the wire to furl all that is above it. So a reasonable sized wire of a stiff makeup is better than something flexible. WMs are bronze eg http://www.classicmarine.co.uk/prodtype.asp?prodtype=79&ph=cat so if yours is stainless it is something else. Pretty much only good for furling ie. not for reefing. Also tends to furl over tight if there is a fresh breeze. Some say it is not so easy to get a tight luff but I don't see why as you can pull them up just as hard. Thinking about it, maybe its because you are tensioning the luff wire and not the sail itself. Not sure. My cutter has two, though I have wondered about "modern" roller reefing for the stays'l.

The bronze one costs a fortune! The one i have is a very solid 6 inch drum stainless one. Cant remember where i got it now?
Its as i thought!
I would put a "modern" one on but theres no point on a Folkboat unless i have a genoa to roll!!
The very very best "modern" roller is the "pro furl" really good quality compact never heard anyone have a problem at all with it!! Its a bit? more costly than most others but the one i havent ruled out buying! And ive looked into roller reafing a lot,
A Canadian in a 14m boat moored next to me in porto azzuro and he had not only roller reafing but another pro furl to roll his main as well!! He told me he had crossed the atlantic with it? The main was loose footed

If the sailmaker's done their bit properly the sail should be set up at the right tension on the luff wire so you oughtn't to need to do more than pull the halliard up as normal. Also it's good to have the luff seized to the wire at intervals along it (say quarters) as well as being made fast at top and bottom.
The main thing between WM's and modern roller furling is the one's designed to be taken in when not needed (in port for a while) whist the other one's semi-permanent, so one advantage of the WM is being able to keep your sail out of the sun with its lovely UV damage, but a sail rolled up on a wire in a coil isn't the most easily stowed thing. On the other hand the modern version is more reefable but the sail doesn't come to much good being out in the weather all the time.

I have a really useful home-made WM hauled out along the bowsprit to set the jib. I got someone to braze up a drum out of bronze. It bolts onto a simple bracket connecting to the traveller, but the nut is locked so that the eyebolt through the middle can turn in relation to the traveller. It incorporates an eye to guide the coiling line (actually made from the rod from a WC ball cock).
There is a balance to be struck when tightening the halliard - too loose and the sail doesn't set well: too tight and the swivels don't turn easily.
Stowage is easy - wind up the sail, haul it inboard, lower slowly, coiling the wrapped tube down on the foredeck, disconnect the ends, and pop the resulting pizza-sized coil into a bag to stop it unwinding.
When unfurling, keep a bit of tension on the coiling line to stop it flying off the drum.
It works after a fashion when reefed, but not very well.

Happy to be corrected, but I thought the wykham Martin system was a furling system rather than a reefing one - i.e. only used to put the sail away, and unsuitable to use to reef the sail.

Thats exactly what it is. A folkboat has a jib no point in haveing expensive furling gear!
A folkboat prefers not to have to stowe the jib.
Far better to leave it bent on then when the time comes to clear out in the dark and rain just pull a line and the jibs in place.
If it was nessasary to reef a folkboat jib it would be blowing far to hard for any roller reefing gear!

But you have been talking about reefing, and that is not possible.

Oh? I just want to leave the sail on the stay. Then i can dive into the clear(cold) water to wash!
I get really fed up with haveing to hank the jib on and off! Particularly when i just have to change bays becouse of the wind.
And my jib dosent just stay on the fordeck,it escapes at midnight just when the rains started.

personaly am a great believer in being able to reef genoa and main without having to leave the cockpit, cause that is when SWMBO starts having kittens in bad weather, and its also when the autopilot starts to misbehave (perhaps I should have bought a better model rather than the cheapest). I have considered very seriously adding a second temp forestay in order to be able to deploy an upwind sail or storm sail rather than the reefed big genoa. The big advantage of hanked on sails is the ability to get the sail down onto the deck and still have it more or less under control. Changing my big genoa when it is on a foil is not a job I relish in big wind.
