hey people,
its been a while since ive wrote something,
the halyard pully on top of the mast 1 meter above the hound how is the pully attached eg, another hound, rope and how methods? which is better? which shoot is better to use the fibreglass triangle or the spin pole with alloy tube welded facing up?

Cheers
Matt

ps, dont get any ideas that im putting on a spin ok, good got it lol <img src="http://www.catsailor.com/forums/images/graemlins/laugh.gif" alt="" />

Matt,

You know you want to rig up a spinnaker. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
Go for it !!!

There must be some images around showing the mounting. I just can't find any in any of the albums. <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />

Some of the swarm with spinnakers must have some images and comments to post. Come on guys. <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />

Regards,

Peter

The spinnaker rigging info is on the VMCA site here

Spinnaker rigging

I admit though there is no photo of the halyard pulley setup. The pulley hangs on a line from the top of the mast and runs on a loop of cord which is tied off at the mast track. This is so it can move around the mast as it rotates. I will get some photos organised and update the web site.

The fibreglass chute on the bridle is way better than a loop on the pole. It is much cleaner and much less prone to snags. However it's hard to construct - hence more expensive than the aluminium ring.

Thanks peter and tim,

I have all the rigging info, thats why i asked cos there is no photo. Now does the rope get tied off at the pully or is there 2 knots just inside the mast in the track, ill figure it out, the fibreglass shoot i can make as im a boat builder, im making a mould for it, thanks guys.

Matt

Ps, i heard that there is going to be a spinnaker titles or nationals in somers about christmas time

I've updated the rigging page with halyard pulley photos.

thanks tim,
wOULD I able to go lighter on the rope from the mast head to the pully, seems to big for that, its looks like 4mm spectra, would it be ok if i go 3mm?
Matt

Hi Matt,

no problem with 3mm, 2mm dyneema would do. But the smaller the more careful you must be with chafing. <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" />

What he said ...

sweet thanks guys

Hi Matt,

OK, so you say you arent rigging for a kite - Then let us in on what you are up to!!!

Trevor

Tim,

You mentioned that the horizonal mouth snagged....curious as to how it snagged and were you using a set up similar to the tornadoes???

Curious that's all

David

I have never used a horizontal ring-type chute mouth, because I have seen how they perform!!!

When I first set up the spinnaker it was easier for me to make a mould and glass up a chute that fitted on the bridle rather than get into bending and welding aluminium.

Once I had that setup I found I could get it to work snag free almost all the time (there's no such thing as always!). By contrast the Taipans and F18s that used the horizontal ring seem to have the crew regularly out the front of the boat trying to stuff the spinnaker back into the chute.

To me it seems logical that facing forwards and up is the right angle to allow the spinnaker to go in. Sometimes the spinnaker can drop below the chute mouth before it goes in and if you have a horizontal ring it has to be dragged up and over the ring in this case.

One problem with the ring is that it is the wrong shape. If you look at skiffs like 14s and 49ers thay have made the mouth wide because they have found that is the easiest shape for the spinnaker to be drawn into. A circle just doesn't work as well.

You'll also notice that setups using a ring, usually have little pieces of string running all over the place to stop halyard, retrieval line, sheets or the spinnaker itself getting caught in one of the corners. A moulding is just so much neater.

There are spiral shaped moulded chutes used on F16s, F18s and Tornados which attach to the pole rather than the bridle. These look good and should work on a Mosquito. The Formula Catamarans builder in SA would be able to supply this one.
