Spinnaker attachment to front hulls

Spinnaker attachment to front hulls - 02/18/14 09:28 PM

Hi all
Just asking what is the best way to attach the end of the spinnaker pole to the front of the hulls with out leaking water
At the front of the spinnaker pole is it best to have the tack line going through a nylon bush at the end or to have a roller inside the pole
I ask these question due to my last spinnaker set up was very difficult on get in and out of the shoot
Thanks for your options

Hi Brett,

I think the hole through the bows is the easiest way, I have glued in a tube on previous boat, but drilled the current ones oversize and filled and then drilled to the right size again. Make the hole big enough for loop of dyneema type rope then use tail to stop the loop pulling back through, makes rigging quicker, than setting length each time.

I have used both the pulley into the pole and the plastic end cap with hole in it for tack line, haven't noticed much difference in drag, most of it is kite in the chute. So I think either way is ok, but whatever you do, put a end cap on for safety.

I think I saw at the wild cat your spinnaker pole nylon bush had a rope ware grove mark in it
I think I like the nylon bush idear I may go for this method

thanks gary

Hi Brett,

rope groove was only from using old fashioned polyester covered spectra rope, if you use dyneema type with no cover, no wear, on spinnaker either.

Hello Brett,
Dyneema and splicing needle should be available at any sailing shop. There is also plenty of videos on how to splice it on you tube. It is super easy and makes an excellent job. There is also a link to a video on the goodall website to splicing when you can only use one end. Even I picked it up in 2 minutes.

I rigged a spinnaker this year and made up a continuous dyneema bridle. I spliced an eye about 70mm from the end, and knotted the very end of the dyneema. You feed the eye through the hull and a flat washer (to spread out the load and stop it jamming), and then put the stopper knot through the eye to lock it in. Ensure between the bit of dyneema between the splice and the knotted end is long enough so there is no weight on it when rigged, otherwise it can cut into the hull, but not too long to flop around. This effectively gives you a direct pull from the washer on the outside of the hull towards the pole.
I put a small roller in the end of my spin pole, held in place with a rivet on the back end and a SS bolt through the pole and roller on the front end.

I drilled into the sides of my pole to provide a straight lead for the dyneema bridles, and then tied a clove hitch knot around the SS bolt in the middle of my bridle. This knot enables you to adjust the bridle to get the same exact lengths, but after you put weight on it it locks in never to slide again.

The benefits of this rig are that the weight of the spin is taken over a broad area on the outside of the hulls, and there is no torque on the spin pole as the bridles are effectively attached to bottom of the sail. All the weight is taken by the dyneema which is more than strong enough, and the pole simply acts like a spacer to hold it out and up.

I am really happy with it and can send you some pictures if you like.

Photos have been sent and you should have them by now Brett. Give me a call if you have any other questions.

Sailed against 'Bite Me' this afternoon at Speers point. Dave started 10 minutes after me, capsized, and had to re round a buoy after hitting it. He was Cat rigged and I had a spinnaker, so you could say the odds were stacked in my favour.

We sailed in a the Presidents cup this afternoon, with all boats starting at the same time on the same course for all classes. I was happy to get a third place after a Hartley and a Tasar of all things. Being the first Cat on handicap against F18s, A class and Nacras was pretty cool, but the wind was better suited to me.

Dave is sailing 'Bite Me' for the first time in 10 years, and despite some trouble had really good boat speed and will soon be keeping me honest. The spinnaker saved the day for me today.

hi luke
I don't seem to have any photos as yet
I think I am trying to go with your idea
I think that I will drill the front of the hulls with a 10mm drill then epoxy in a 10mm pvc pipe to run my spinnaker bridels through
the problem is I cannt find any 10mm pvc pipe to do this procedures
thanks luke

Why so big? Only make them as big as they have to be to get the rope through.

When Peter put the holes in the bows of Red Alert (a very light plywood boat) he stood the boat on it's nose and filled the tips up with epoxy filler so they would be a solid and waterproof attachment for the bridle.

hi tim
I through that you drill a hole about 10 mm and use a 10mm bush or conduit to seal the hole and glue it up so you can remove this rope
I had this idear from the f 18 and vipers
I don't thing that this is be the best way but at the moment this is all I have to go buy
I just want to go sailing after selling my boat I don't think that where was so much work in getting finished to get on the water
thanks for your reply tim greatly appreciated
