It's actually suprising that more classes don't use twin poles, espescially trapeze boats like the
fireball. as the pole is not centreslung it doesn't need to be quite as beefy in the middle and they wouldn't
need that silly kevlar wrap.


I agree with your analysis of the current Fireball pole setup (ie, it's a bit rubbish). I recently had quite a
long discussion with a variety of Firebally people on a couple of forums, and the upshot was that Fireballs
definitely aren't allowed to have twin poles. I know this has upset a few people, particularly the ones who have
been using them. Personally I'd quite like to have twin poles on my 'ball, but I'm not going there if they're not
class legal.

I sail a merlin.

If i had a crew who could use one i'd try a single pole. The twins are marginally faster to launch, but with the single a gybe needs less advance planning. I beleive that the length may be an issue for some but i used a single alloy pole as a crew just after the rule change to the long pole and didn't find it a problem.

There are a few boats with twinning lines but not many. The reaching hooks are IMO better if properly located and no hassle to engage.

The Merlin twin pole system does not use a spiro launcher and is mega quick and elegant to gybe.  In terms of twinning lines i can't remember my system well enough.  I'm sure i had twinning lines on my boat??  I will try and dig out some old photos.

Nobody seems to have told the Merlin boys this, they seem to manage some swift and elegant gybes!

Incidentally, I was looking at the Merlins at the show, none seemed to have twinning line for the spinnaker guy. I was surprised by this, on a class that likes a bit of string here and there.... Anyone know the reason?

If you can gurantee a crew who can use a single pole that's what youi want. If not then twins are the way forward.

Have a look on the merlin web site. They have been using twin poles for ages and have some very refined systems

That balooney sail is going to give you banjo boys such a pasting you wont know wether your
cleaning windows or fanlight fanny.

As to the pole thing isn't that a quick boot up the jacksy to the crew sort of thing even back in the olden days when
crews used to put up quaint devices like spinnaker poles.

Proctor Pole Launch System

This is labelled at P&B as the Proctor (Selden, who?) pole launcher, but it's just like the Spiro. Means you can just pull a string to launch a single-ended pole for your symmetric kite - that looks a bit like that balloony sail that's been limiting your upwind speed on the Alto, GRF.

we use a spiro on the N18, its a very quick system and very easy to use, just have to remember to not get in the way of it when it comes back!  i would say its not a delecate as a conventional system when used in light airs but when the breeze is up being able to get the pole on and quickly outwieghs that issue.

I am about to start experimenting with a twin pole system on my FD, I have fitted the system and it works very well with dry drills I now need to try it in anger.

Initially I am using the system without the through pole lines to the spinny sheet/ guys as I would like to make sure the basic system operates efficienly first.

With carbon poles these days the additional weight is small, yes there is extra string but once its sorted, all that is needed is to pull the launch line to set and release to stow, if the bunghy is routed correctly the helm (me)  will keep his teeth, unless he makes a habit if putting his face on the boom to hold it steady.

I will post some pictures after the weekend.

Incidently if you check out the latest Pinnel & Bax catalogue you will see the twin Spiro or 'Spinno' as it is known is now being offered, although it aint cheap.
