How high should be the spinnaker hoop from the water line?

Last week I went out with my new home made half pole snuffer system. When I was going through waves made by power boat, the front of the hulls went up and on its way down the hoop went under water. I ended up with the sock full of water.

How do I get the water out while the spinnaker is snuffed?

Thanks

Usual snuffer sock material doesn't trap water. Its a very fine almost-mesh-like material that you can almost see-through.

...or if you don't have a mesh bag the other end of the bag should be open so the water flows out.

I always thought that the snuffing bag should be made out of water resistant material so the spinnaker will not get wet. My snuffer bag has open end but when the spinnaker is snuffed there is no way for the water to go through. So what material should snuffing bag be made of?

I made my snuffing bag out of ripstop coated nylon and supported with sunbrella material by the hoop see picture attached.

What should be the diameter of the snuffing bag? My hoop is about 12 inches in diameter and the whole bag is about the same. When I installed everything on my boat I saw bag dragging in the water. Should I taper it on the back?

Tapering the bag is nice, as long as it is a straight taper.

The spi will get wet, either becouse you drop it in the sea, it rains, spray, capsizes/cartwheels or you scoop water into the snuffer. You can cut small holes in the bottom part of the bag to let rainwater, seawater in the spi etc. drain if the bag is positioned so flat that it dont drain out the end. Or you can get/make a bag from a material (swimming pool cover?) which lets water trough while offering low friction. We have used a ripstop nylon (not sailcloth) bag succesfully for some years now, but ripped it during the swedish nationals. Will be making a new one in mylar with small draining holes along the bottom.

That happened on our 6.0 as well with the spin up, not snuffed. The water made the bag sag and eventually tore from the pole. You may want to consider adding a mesh section to the bottom of your bag for the entire length. Or supporting the bag the entire length of the pole

It happened to me on the I20, end pole snuffer, during this year’s c100 going down the middle of the bay, downwind with the spin snuffed. I had just coated the spin with McLube prior to the race, and I think that caused the water to remain longer than it would have uncoated. We were already almost pitchin’ it every other wave then with all the water weight up front it was really ugly for about 5 minutes. I think it slowed us down considerable, which actually helped.

What is that pole made of? It looks like galvanized steel? You also may want to consider getting longer bridal foil wires. I think the NE 6.0 added 8" or went to 8" inch wires to raise the foil and the top of the pole. Rick Bliss suggested I do this with the 6.0.

I use nylon cloth I got from walmart. it seems to work ok and doesn't seem to collect water. I haven't had a problem with mine digging in for the most part but I actually have my hoop about 1 foot in front of the bridle foil. How are you attaching your bag to the hoop? I have had problems with mine staying attached

Chris9 I think you have good point with adding mesh to the bottom of spinnaker suck or maybe even making the whole bag out of mesh.

Talking about ripped bags. See picture. When I was done sailing I took spinnaker pole with me to fix it. I left it by the car and went to get more stuff. When I came back the pole was few feed away from my car. I think the car parked next to me had to caught it when it was pulling back and drag it for a while.

The pole is made of aluminum it looks like galvanized steel because it was painted before and I scraped the paint. Also I used aluminum rivets to attached support wires to the pole. Big mistake one of them snapped when I had my spinnaker up and almost bent/broke the pole. Now I will replace then with stainless steel rivers or just ss screws.

It would be tough to add additional 8” to rise the bridle foil I have furling jib and not much space left. Has anyone done it???

Here is the close up of sock attachment to the hoop. I used flat aluminum bar and 3 rivets.
Green sunbrella material and Velcro.

Kris,

the bridle pole rise was pretty standard for the New England configuration. I believe they simply used the additional mast rake to help with tuning the spinnaker downwind.

PTP,
Nylon cloth from walmart. I am interested, how do I find this material?.

should through bolt the attachments to be sure they stick around- either all the way through the pole or with a washers in the interior. I had one eyestrap go once when it was just riveted (of course, a monkey could have realized that a rivet into a glass or carbon surfer mast wasn't going to hold <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />

If you are in walmart just go to the "crafts" section and you will see all sorts of cloth. My mom actually sewed the bag for me and I wrap the bag around the hoop and secured it to itself with velcro. in retrospect I should have done a better job of measuring it and after sewing the bag twice I think my mom is a little burnt out on it <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

I was able to find one source that supplies spinnaker bag material

Which of those three should I buy to saw the spinnaker sock?
