H20 spin
I will post some pics on my homepage for you. First, locate a small mast tang, perhaps for a H14 or Laser, place it between 36" and 37" abov the end of the aluminum portion of the mast on the comptip. See address bekow

Brad, I am working on it as you speak. I am on vacation until Jan 5th so I will have lots of time to make something. I have some preliminary designs already. I'll put the pics on my home page this morning some time. I am starting with an extra mainsail bag and the top 4" od a 5 gallon bucket? "El Cheapo Engineering Co. Inc."
I'm not sure of the exact dimensions. It looks to me to be about 10" wide tops. It also seems to taper back to a smaller diameter down the tube. The tube is made out of fibreglass. It looks like it is very thin. It also breaks and cracks quite easily. All of the friction comes from turning the corner on the top side of the hoop. One key is to have a flat turning piece so that the rope doesn't always burn to the same spot. I've seen tennis rackets used and just some homemade hoops.

Hi guys,
The tube is made out of vinylester, and is kinda oval.
It is 6.5 x 7.5 inches inside at the mouth.
The top of the mouth is aluminum that is glassed in and faired. It is about 7` 3" long
The whole thing weighs aprox 2lbs and as mike said is very breakable. My kite came with 2 bellybuttons but I think I need to add one more.
OK guys,(and Brad) we are getting ready to make our first mold for "El Cheapo Engineering Snufalufagus spinnaker thingamabob.TM, copyright,patent pending (or not pending) etc. Inc., Co. LLC. please see prospectus for actual risk that was probably not disclosed by the snakeoil sales punk.
Anyway...this should be interesting..gimme a Bud so we can start with the glass work
I should have been asking my questions here! I'm looking at putting a spin on my 20, after having done it for my 18.
I noticed the halyard tang is just pop-riveted into the comptip. What length rivets did you use? Any tips to keep the action of riveting from making cracks in the comptip?
What size spinnakers are you guys using? Are they the Tiger spin that Hobie seems to be selling for the 20 now? Or something else?
In the Chesapeake Bay area the 20 sailors are starting the debate of whether to add chutes, and if so, what size. Maybe someday we'll have a spec, something like the NE N-6.0 sailors.
Keith, the comp tip is very strong, don't worry about it breaking. I can't remember what length rivet I used but after you drill the holes you can see the thickness of the material and go from there. Make sure to use the rivet "sleeves" and sealant to keep your comp tip watertight.
Ok, let's try the question a different way!
Is anybody out there using the spinnaker that Hobie now sells for the 20, which appears to be the chute from the Tiger? What are your impressions of this sail on this boat? Just right, under-powered, etc. etc.?
Any info on this would very helpful, so even if you know a friend of friend who knows somebody who heard a story about it from somebody else...

He announced that the was testing the Tiger chute against the usual Hobie 20 chute on the open forum.
Don't know the outcome and I would be interested.
Take Care

Keith, I just bought the spin for my H20. I don't know if it is the same spin for the Tiger. i can tell you that the foot is long enough that I have to sheet from the rear beam. I have ony flown it once so I can't at this point make comment. I hope to get it out again soon. I will post my experience.

I just posted a pic of my spin on page 4 of the "pictures" tab on the link above.
I took some rudimentary measurements....
tack to clew = 17 feet
tack to head = 26 feet
clew to head = 24 feet
can someone make a determination from these rough numbers?
I would also like to know what I was sold....
Ok, I've looked a little bit more at things, and maybe I've confused things by interpreting what I've seen listed...
The '02 Murrays catalog shows the spinnaker kits by Hobie with the following dimensions for the 20 chute:
luff - 27.58 leech - 25.0 foot - 17.0
Given the fun of laying out spins and measuring them, this is probably the sail you have. The most recent Hobie catalog I have shows the same part number as this kit.
The '03 Murrays catalog shows the Hobie spinnaker kits with the chute for the 20 being listed as Tiger/20, with the following dimensions:
luff - 27.56 leech - 24.33 foot - 12.0
Similar luff and leech, smaller foot. Depending on who you believe about spinnaker design, the higher aspect ratio design on the Tiger sail might be just as fast without the extra sail area.
But I guess my question now, is what is Hobie actually selling for the boat if you were to get a new one now that wasn't old stock? I'll have to dig a little more I guess...
Wow! 5 feet longer on the luff than either "stock" spinnaker for the 20. I knew I-20s had taller masts. It's interesting to see that the foot is the same length as the Tiger/F-18 sail.
I'm guessing this would put my halyard a little further up the comptip than I should go, I'm not sure a reasonably longer pole would get me in the right range...
Keith
The mast is only 1' longer. You could drop it down a foot and lengthen the pole. The 6.0 NE is running the same height as the I20. I think Chris Bolton is running the 6.0NE spinnaker on his 20. I am not sure what the head to end of pole measurement is. Rake the mast back as well. Maybe one of the FLA guys could measure it.
