Hobie 18 Spinnaker Group Buy Feeler, Any Interest?

Surf City's kit that I got last year came with 8mm Robline Racing and the halyard was one for a F18 which had the cover striped on the retrieval side, of course had to shorten some.

Would buy another if Hobie would build it.

I guess stripping the cover is one way to do it, didn't think about that option.

Well I just ordered my black sail... waiting to see if someone goes for that crazy raspberry color

So we don't have to make a list before placing an order. Chip is just doing a 50% deposit on your initial order and then the discount will be applied when you pay in full before shipping so you can order individually. No need to wait for us to get a list together.

Just to be clear, the spinnaker sheet line was 8mm Robline, and the halyard was some other high tech 3/16" line with the cover striped of the retrieval side

I believe Chip made their H18 spin(dont quote me) as well so I think you may have the same sail we are getting. Don't quote me, just a guess.

Yes chip made theirs but orginaly I was going to try and use a F18 spin that I bought used so i bought the kit without the saiil but with the comptip I didn't want to mount the bail that high was i put everything together so chip gave me a discount on a h18 spin that he had cut but the customer backed out.

Nice. I'm curious about what pole fitting you used to attach to the front beam? I have a spare mast gooseneck fitting like I believe their kit uses. Was thinking about just making a resin plug that I can rivet in and just add a gooseneck pin exactly like the boom uses.

Did you have to deal with the bows diving at all and having to play with the pole length?

That is my boat (Windraider) featured in the first instructional hardware installation video. Still available for sale on thebeachcats.com if anybody is interested.

I bought a 12' F18 spin pole and the aft end cap had a small hole for fiting onto the F18 spin pole fitting on the front beam. I just drilled the rivets out of the cap, made the hole larger in the end cap put the boom pin onto the cap and re rI've ted the cap back onto the pole.

I think that's the way to go. Still might just make my own plug but will hunt and post a part number for anyone else not wanting to go to as much trouble. Not going to get more oem than that.

Not sure what size of ca you need for your spin pole but Murrays sell the Nacra rear pole end cap, they have the diameter listed with the item

I have a lead on a shop near my beach launch spot that sells new/used windsurfing masts pretty cheap. Probably getting a standard diameter mast in the next few weeks to start adapting to my boat.

Reduced diameter masts(RDM) masts have a 33mm or 38mm inner diameter. I've read both.
Standard diameter masts(SDM) masts have a 48mm inner diameter

I've added some new documentation to the first post of people want to read it over and make sure I didn't list or say something totally wrong.

Keep in mind there is a bit more to windsurfing masts than just SDM vs. RDM. Masts vary quite considerably in stiffness, generally based on the length of the mast. Therefore, on a per-length basis, a 15 foot mast (460cm) is a heck of a lot stiffer than a 12 foot mast (370cm). That may not be terribly critical for your application, but it's worth noting, especially if you're trying to control the bend of the spin pole. You may find that you're better off buying a mast that's a bit long and trimming it down to length so you get a stiffer section. The stiffness between different masts can be compared by referring to the IMCS number printed on the mast.

Also, if you're looking at using a composite mast (which virtually all windsurfing masts built in the last 25 years are), keep in mind that composites really don't like point loads from things like rivets. So if you're planning on riveting fittings onto the pole, you're probably going to want to use some type of internal backing (like a washer). Also, beware of cheap used masts that have sat out in the sun for long periods of time. The UV rays will kill the composite and could lead to failure.

Good point. That's what I was thinking about the rivets. I drew on one of the photos that it would probably be better to loop the line under the mast and just use a riveted eye strap to keep the line in alignment rather than pulling directly on the eye strap.

I figure I'm just going to go for the stiffest thing I can find Although I'm imagining due to having bridles that attach right under the tack point and near the middle of the pole that much of the potential flex is restricted. Anything you can do to spot UV damage?

My neighbour at the sailing club does not race.
In fact, his H18 (with SX wings and spin) has been sitting doing nothing for 3 years, as he is too busy sailing his 33' Beneteau....
Nota that I agree.....however, his spin pole is a length of galvanized fence post!
Sure, it's cheap, can be riveted, a little heavy, but it works.

My buddy who sails a F16 Blade, broke his spin pole when he port-sided the 29'er fleet at a local regatta.
Ooops! He replaced it with an equivalent diameter aluminum pole from a metal supply store.

Both poles were not expensive, so there are alternatives.

'Only two things are infinite, the universe, and human stupidity. But I'm not sure about the former.'

Signs of UV damage would be faded color, exposed or visible fibers, splintery/pricky exterior surface that sheds fibers (into your hand...). Pretty much the same as a UV damaged comptip or EPO rudders.
