I want to re-open the discussion about the different types that are available.
I'm in the process of purchasing the snuffer ring and bag for my Mossie .Some experience/feedback will help to decide which one to choose.
Obviously the triangle shute mouth is very popular with the Mossie fleets down South. There is at least one boat using the horizontal snuffer ring most commonly seen on F18's etc,(I think it is Kryptonite. Daniel Stone ).
My boat is timber and has had a spinnaker on it at some stage, I have the longer bridle wires and the popular triangular shute mouth would require shorter bridle wires,would this put to much strain on the hulls.
Please give us your opinions on the difference. Thankyou.

The "dunny ring" you can get from AHPC (goodall design) is good. But in saying that it is good cos it comes on and off neat. the disavantages are when pulling in and out is harder due to the angle. since ring mounted on pole it wants the twist the pole, need longer haltyard and sheets.

THe triangle chute is good also. You can order one from me ($80 for chute mouth $80 for bag) Advantages, can ust any size pole within the rules and alloy or carbon. Mouth can be made with your choice of colour,
disadvantages. pain to change from spin to cat rigged unless you have 2 bridles, or use the one and have to rethread the bridle thru the chute

Just order one about 6 months in advance if you get one from Matt. Apparently the time lag has something to do with him being a Rannger.

Hi Matt.

Thanks for the reply
Some really good info here, that's also a very good price. A well known dealer up here wants to charge more than twice that price for the chute mouth and bag.

I still have the question about the strain/stress on the timber hulls with the shorter bridle wires. Will they be safe to handle this set-up .

When I do decide on which type to go with and if I go with the triangle mouth what is the preferred method of ordering and payment trough you Matt.

Thanks. Dave.

hi Dave,

Depending on who made your hulls will determine if they are strong enough. We have 2 Carter built timber boats with short bridals (one mk1 one mk2) at our club that we have had kites on for at least 4 years with no probles.

I use the AHPC "dunny ring".

It goes up when I pull it up, It comes down when I pull it down. Haven't used the triangle so I don't know if its harder or not. Pole twist not a problem. More expensive than the triangle but very convenient, and they also a supply a pole to suit the ring (you cut it to size) and a chute made for the Mozzie

It's basically a viper pole and ring with a mozzie length chute. If you've got the bucks, it's easy to set up, and very convenient to add/remove from the boat. If you're on a budget, lot's of people use the triangle so it must be good. Plus it's always good business to do business with the President wink

Simon it is a bit of a worry if it goes down when you pull it. But I guess at your age....

Dave you can check in your timber hulls to see if they have been strengthened.

If you look into the forward hatches there should be a plywood strengthener on the inner sides under fwd beam. It should be tapered at the edges and roughly a foot square. The tapered edges prevent a hard stiff edge or pressure line and it should strengthen the hulls at the stress point between the bridle trying to pull the hulls together and the fwd beam holding them out.

My limited understanding is that when boats went to the shorter bridle they had some problems with stresses and this alleviated it. As long as it is still solidly laminated to the inside the kite should not be a problem.

From some of the recent posts it may be worth while checking the anchor points for your bridle too. The easiest way to do this is put a camera and light on a pole and poke it fwd. In a 1/2 hour footage you will probably only get 5 seconds of what you want to see but on a digital camera it doesn't matter. Also a good way to check the glassing around your dagger board case without ripping hulls off.

Thanks guys for the feedback, this is helping to decide.

Hi Luke. I have just checked one of the hulls and it definitely has a hull doubler inserted. Although larger and not glassed on the outer edges.

The newer timber hulls seem to be using a second half bulkhead frame under the forward beam pad.

The mossie that I have I think originally came from the Gippsland area. (Someone surnamed Wilson ).

At this stage I'm leaning towards the round (dunny ring) type.
Thanks Dave 1724.

No worries Dave,

I have a triangular chute mouth and find it really good as you are always putting the kite up and down heading down wind so it feeds in easy. I also get not torque on the pole which is great as another less thing to fail. Most guys seem to go for the triangular but they both seem to work. Personal preference really.

Just have a look at your hulls after you use the spinnaker the first few times, and if ensure there are no cracks or deformations, but sounds like you should be right.

You should wish, and be lucky to be going as well as I am at my age Luke!
