I have a guy selling a Hobie 18 jib furling rig and I want to know how hard it would be to make this work for my Prindle 18?

What are the differences and what do I need to look at changing?

Also the Hobie 18 jib comes with it how does it compare in size and shape to the Prindle 18 jib?

Would it be best to just have a new forstay made with a thimble that can hook to a chainplate on the furler drum rather than the prindle forstay?

Does the top swivel go below the upper forstay or above?

One say the Prindle furler kit from Murrays it looks like they shorten the upper forestay to make up the difference in the furler swivel and drum. is it a big deal to keep the same one and shorten the lower forestay if I am making a custom one anyway?

It looks like this one is left on the mast with the jib furled around it when the mast is taken down is normal or the best way to do this?

I'm sure I'll think of more questions but that;s good for now.

if you download the texel ratings spreadsheet you should be able to compare jib sizes

You will need different bridal wires. The ends need a clevis
so you can pin them to the furler. On my p16 with h18 furler, the furler bridals are shorter. You might get away with using the h18 bridals though. The h18 jib has a zipper
and it is raised and lowered on the forestay with a halyard.
The p16 is the same.

If you look at the Hobie furler, it requires specific bridal wires, if you can get your hands on these bridle wires makes things a whole lot easier and cheaper. I opted for the Harken furler, it connected to my chainplate. All I had to do was measure my old forestay, then I measured new jib + furler + swivel and ordered a pigtail from murrays to make up the difference. Presto, roller furling jib.

OK Thanks


Turbo: I though the chainplate would have gone on the top of the furling drum?

In my setup, the bell shackle was too big to fit through the Harken furler, and I did not want to downsize on the shackle due to the tremendous stress placed on this area. So I just went that route. If you have the hardware, then try with the chainplate on top of furler, makes no difference.

Not crazy about furlers as added cost and people tend to leave them furled in the sun too long--burning the sail, unless an extra piece of material is sown to leech or last furled part which again adds to cost. Pete

It kind of defeats the whole idea of the chainplate though. You can no longer adjust rake.
I wouldn't worry about over stressing the bow shackle. My Nacra 5.7 comes stock with shackles that use 1/4" pins. The holes in the Harken furler are sized for 1/4" pins, that is what is used on Cats up to 6 meters (20 feet).
You will tear the 6 or 8 rivets out that hold the mast hound before a 1/4" pin will fail.

My boat does not live on the beach so the furler would be for camping sailing weekends leaving the boat rigged on the beach. For storing on the trailer I would either drop the jib and stow it or make some sort of cover for it. I hate manually furling it especially if there is any wind involved while doing it. Besides I was only looking because this was a used setup from a hobie 18 so I was hoping it would be easy to make work but it sounds like it might involve more than I want to do to make it work.

Let me know if you ever come across any P18s that have the Murrays Prindle furling kit on it. I might be interested If it's cheap enough.

how much is he asking for the setup? If the bridals will work it really won't take much to make it work. I use a jib
sock when I leave mine out. Takes like a minute to run it up
with the main halyard. I love the convenience of being able to furl as I approach the beach.

What do you use as a sock? That may be way cheaper than having a sailmaker sew something on. Do you have a photo of it & how it works.
Thanks

I bought mine from a guy on ebay. Got lucky and bought it
for $40. It just zips on as you raise it by the main halyard. See the link for one at Murrays. Decent picture so
you can get the basic idea.

He was asking $125 for entire assembly. Forstay, top swivel, lower drum, and H18 jib.(blue with window) maybe even the bridles. Not sure if I could use anything but the drum and swivel but if it's in decent shape I could probably sell the Jib for the $125. He wasn't interested in selling me just the furler attachments it was all or nothing.

Can't go wrong at that price. the drum assembly usually goes
for $100 used. the swivel is not cheap either. Another thought. Does your jib have the short battens like the p16?
If so you will have to remove them to fully furl the jib.

I just installed a brand new assembly including jib on my Nacra 5.8na. I bought a jib with a UV strip so I did not require a snorkle cover. I got the whole thing from a dealer through Murrays and it cost me a grand. Well worth it.

Challenges...

1) I had to send the forestay back because it was too long
2) It took a while to get the geometry right.
3) I had to change the line in the Harken drum.
4) The swivel needed lubrication to get it to work right, I'd reccomend a sealed bearing version.

I'd say getting the geometry right is your bigggest challenge.

Note that a custom kit at Murrays is north of $350 plus a snorkle for the sail is another $100. A jib with UV strip is north of $600. So if you can retrofit this is a deal.

Lawrencer2003: Yes I agree it's a deal if it's not too difficult to get it all working ok. No way I'd ever be able to sink a grand into it so something like this is my chance.

pknapp66: Yes it has the mini battens or one at least the other is missing anyway and I intended to remove the other. they are so small I can't see them making much difference at all in my sailing as I don't race in anything other than casual fun stuff. I was gonna remove it whether I put a furler on it or not as I quite often manually furl it on the beach anyway.

Dustin,

When you get this all figured out please take pictures and write up a parts list for the conversion. Would be a good addition to the Beachcats Technical album.

Those little jib battens may not seem to do much, but I find they do quite a bit to keep the leech from flogging. I removed mine one day, & in heavier air the leech tended to flap a bit. Put them back in & the flogging stopped. Granted mine is an original sail for the 5.7, (though it seems in very good shape, no tears) maybe newer ones are stiffer, different geometry.
It probably doesn't make much difference speed wise, I don't have a GPS to try and experiment with any accuracy.

Damon I will if I actually end up getting it. My vehicles keep breaking down and I can't spend the money on anything fun till I can get at least one working.

Dustin, get the furler and sail to work. :)

i wouldn't sail without one unless i had to. i am all day and see all kinds of weather (last week we had waterspouts) and require the need to furl.

I was at the sailmakers today, getting the new forestay for my furler,(I know, I know, it's been months & I still don't have it installed)& happened to bring my Invitation sail for a repair after the kids ripped the leech in a big blow.
I inquired about getting the Nacra jib tweaked for use with the furler, & the gal told me they remove the two battens, then to make up for what they do, she will sew a strip of stiffener into the leech. She said it will work as weel as the original, & that without it, or the battens, the leech will tend to flap more.
I am taking a bunch of pictures, & will build a new album that will hopefully save others some legwork.

Quarath, if you dont end up buying it from the guy, want to PM me his info. I concidentally need a furler, forstay, upperforstay, and swivel.

If he still has it and I don't get it I will do that. It is in Utah. He had a Hobie 3.5 and a 14 turbo for cheap I wish I could get for boys as well. He also had a Gin pole setup I was hoping to acquire.

Finally got my Suburban to pass Emissions now I need to get the wheel bearing fixed and pass safety. Only 3 months late. gonna have to try to sell my Caravan that lost the Transmission. My Dad picked up wrecked Venture he's getting fixed that may replace it.

EC,
Let me know how that works for you. My furler works awesome (it is an H18 setup by the by) but I removed my battens and they are correct, the leech tends to flap around quite a bit. I am going to get one made this winter with vertical battens, but the stiffener is intriging.

I think that sail cut is also a factor. I have a 4 oz jib that is completely flat (not that jibs are overly shaped anyway) made by a local tarp guy and the leech would flog uncontrollably, it is now very close to toast and I doubt I will ever use it again. Live and learn.

I'll let you know Dave. I stumbled on a little shop in Barrie ON, SOBSTAD SAIL, they actually make sails, repair them, & seem very knowledgeable. The rigging guy works with the Olympic team & seemed very helpful. He said he raced Cats for 15 years.
I don't have forks or marine eye on the end of my bridle wires, just the cheaper thimble & loop. They are new, so I don't want to change them yet. He didn't like the way a shackle fit the end of the furler drum & the bridles, so he is making up a system with the triangular plates.
The chief sail sewing gal invited me into the loft, interesting, as I'd never been in one before. As soon as she looked at the Invitation sail she told me it was in fine shape, & pointed out a small leech tear that someone fixed before, (improperly) She said you couldn't just resew the torn part, as it would "pinch" the sail. Anyway, she will remove the entire leech seam, tape it, then resew it. About an hours works she said, & $90-$110.
Anyway it was good to find this place, they have been in business for 40 years, & prices were better than the other shops for line, rigging etc. That place might be an option for you.

Yeah they sound like they know what they are doing! I actually have a really good local sailmaker for repairs who is the local hobie dealer also (not the tarp maker that made my original sails).

I went to Chip Buck because my local guy indicated that he had never done a flat top sail and wasn't familiar with how to design one properly. He is actually now a distributer for Lee sails out of Ontario.

I really like what Chip did for me and his background with Hobie's loft and sailboard sails seems to really add something to his designs. The main he made me is super powerful, probably too much so for me. And the quality is second to none. The only issue I have is that I believe he made the sail to specs for a post 1985 5.2 that may have used the ring and hook method of attachment at the top. So the Luff is a little longer that my original which means I can only downhaul so much with my 6:1 until it hits the boom gooseneck. I'm actually thinking of lowering the boom gooseneck 3-4" to make room for more downhaul (rather than fooling with the sail). Not 100% sure at this point whether I actually need that much flattening on the small lake I sail on.

D.
