Hey,
I have told three people I would send them some pictures of my 5.2 spin rig, but instead I thought I would post them on here again. These are not close up shots, if you want to know specifically how to do it I am going to do a write up here about it.

1. You will need all the parts, you can try and fabricated them yourself or you can order them online from Murrays.com (sorry rick you don't carry alot of the Nacra stuff in the online store) below is a list of parts and links to them

Pin that mounts on front beam where the pole sits
http://www.murrays.com/mm5/merchant.mvc?...p;Store_Code=MS

Spinnaker Bale (this is what the line at the top runs through at you hoist to)
http://www.murrays.com/mm5/merchant.mvc?...p;Store_Code=MS

Pole (just about anything will work, but about 12 feet has worked well for me)
Snuffer hoop( mine is aluminum but you can buy carbon ones from ricks online store I believe)
Spinlock cleat to cleat the halyard
4 ratchet blocks

Step one:
I drilled a hole through each bow then refilled that with epoxy. The hole i drilled was about 3/4 of an inch and then once the epoxy hardened I redrilled a 1/2 inch hole. This was to make sure I was drilling into solid hull. You can see in the picture above that I ran a piece of non stretch line through the hole and tied a figure 8 knot on the outside and a loop on the inside. this give me something solid to attach the bridle wires that support the spin pole to.
You can also see that I have bridles that run to where the bridle wires attach. This supports the middle of the pole.
In the picture above I have no prebend in the pole but I now run with about 3 inch's of prebend in the pole that I pull into it using a truckers hitch on the two bridle lines up front.
To support the pole vertically I have a loop of low stretch line tied around the connection of the bridles and the forestay. there is also a metal support that i made out of 1/4 inch stainless cable just like your shrouds would be made of but it was a pain.

Step two:
To ready the mast for the rig I mounted the spinnaker bale about half way between the shroud attachment point and the top of the mast. This may be a little high but my mast appears to handle it okay even up to 25mph wind as long as you keep the mainsheet tight to provide support for the mast.
Above the bale I mounted a block which the halyard runs up through and then back under the bale.

That is really all there is to the mast setup, it was simple enough. depending on the spin you may have to adjust the hoist height but you can change that or the pole height. Both can cause problems so be careful.

Step three:
Rigging the sheets was pretty easy for me. I run an inter 17 spin and pole so if you have a different spin or pole you will run into some different issues.

For the outside set up blocks i have them attached at the shrouds to the bottom hole in the adjuster. This has worked well for me but you might want to experiment with farther forward or back. If you go forward just use a backer plate of some kind and bolt and eye strap to the hull. But I would be careful with that setup.

from that block the line leads to a block on the front beam, this is another ratchet block. It is attached at the same place where the wire for the jib blocks is attached. But you could adjust that depending on where you wanted it but I have found that to be about ideal.

Then the sheet leads to the other side and through two more ratchet blocks that are mirrored of the two I just mentioned.

Depending on the wind speed I either run no ratchets on or both on both sides on.

In this photo you an see where the halyard cleat is mounted, it had worked well for us, but you do have to be a long way forward to hoist and we have had a few issues with the crew being so far forward at the bear-away as he starts to hoist.

Here you can see the spinnaker flying in the front yard. There isn't much detail but you can see what you will end up with.

In this picture you can see the white sheet, that is the spin sheet. This is about the best one I have that shows how it is ran.

Here is a picture of me flying all three sails in light air. The snuffer rig makes it possible and actually not that hard to do.

If anyone has any other questions just ask on here, I will try to get on here once daily to answer any questions.

Disclaimer.... I am no expert and have extra hulls at an extra mast at my house so I didn't mind taking some risks.

SO you have tested your new spin at 25mph? Yea Haw!

You would rather mow the lawn than sail? You sick bastard... <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> The lawn will still be there when the wind dies.

Apparently the wind has been blowing steady there for the last couple of months <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

That is actually the lawn next door, my front yard had a sunfish in it and it is mowed.

You've got great neighbours, you dump all your gear on it so they can't mow the lawn and you keep yours neat. Does your wife know you own a cat? Thanks for your posts its perfect info for my project.

You might want to think about adding *some* prebend to that pole.

In one of the posts I stated that after some tests I did start prebending the pole. usually about 3-4 inchs based on what the wind is doing.
