Gordon, it would be easier asking a stone to become an organ donar.  I have sent pictures of the twin Spiro to my Dad, who thinks it shoudl be easy enough for one of his fabricators to make so watch this space (if i decide to go down the twin pole route.)

A couple of years ago a competative Opsrey set up a twin spiro system - and told us all how wonderful it was and we should try it too ....  up to the point when he took it out.
 
When it was good it was excellent but when it went wrong, oh boy!
 
There should be no problem with crew weight in the front of the Osprey at sea - but where the spiro is more likely to be useful is if you have a lightweight crew who lacks the strength to push the pole out those last few inches.

I think i am going to ship one of these in from the states, it works out to be about 160 including P&P, so is much cheaper then the Twin Spiro, and looks sexier in carbon!! 
 
Does anyone know of a good supplier of cheap carbon poles that would be up to the job?  A CST one is about 185 including ends.

but apparently that's different and we are allowed two of those (phew!). I would have been inclined to argue my point
further, but I was debating this with the Fireball International Class Rules Bloke, so his opinion is clearly going to
carry a bit more weight than mine. In fairness, I can see his point of view now it's been explained to me, but I still
think it's a bit of a grey area.

For the full explanation, see this post on the
FI Forum

Maybe I should look at what the Merlins get up to with single poles....


I fitted twin poles and a twin spiro to a Sandhopper (shoal draft Squibb) and it was brilliant, particularly when gybing. Personally, I don't like 'unwritten' rules. I did a load of research and found that virtually all classes use the singular 'pole' in their rules, including the Merlins and 505s. The 505 chairman of the technical committee told me that he had never found a need to change the wording to read 'pole or poles' or some such.

I don't think you can avoid using a purpose made fitting, loose blocks would be a nightmare. Incidentally, you don't need a shockcord return to retrieve the pole which means you are far less likely to suffer a pole in the mouth. Check out the Merlin Rockets, they have a micro block on the inner end and a high set line (or shockcord) at the mast down to the boom end that allows a much more controlled retrieval. That worked for me too.

Most of the Javelins have gone for self launchers; but not necessarily spiros as they're "expensive" and we're tight (hence lack of carbon spars!).

The launch rope just goes through a metal "U" on the mast.  Gettting the last few inches of pole out is hard work sometimes tho as the ball won't "pop" the last bit.

For me, the self launcher is a vast improvement on the double ended pole as you don't have to stand up at the mast (ie in heavy swells and a nose-dipping following wind) to get the pole sorted for nearly as long.  Javs go down hill quite dramatically when they start to dip the bows! Drops are MUCH quicker too.

Never seen a Jav with twin poles - sounds like FAR too much rope.  Tangled already.

I promise, I'm not digging up a ten year-old thread to be amusing.

You gentlemen's awareness of spinnaker pole-handling options in 2010 and earlier, was far more advanced than mine is today.

I'd like to fit a system to my Mk2 Osprey so I can handle the spinnaker without needing any input by the crew; in fact, without needing a crew. The necessity to leave the tiller to play with the pole, is stopping me using the kite.


I haven't identified what I need or if there is much choice. Two poles or just one? And which mast-fitting? I need it to be launchable from the back of the cockpit. And, since I won't be anywhere near the mast at any time, I need to be able to 'unlaunch' and retract the pole equally remotely. 


All the pieces of kit seem villainously expensive, so if one setup is markedly better than the others, I'd like to know which. I looked on the Osprey forum, but there's less chat on the subject than might be expected; and I know nobody with a remotely similar boat.


I'm hoping that doubts expressed here about the systems when they were new, have been consigned to history. Is it now a foolproof process of carefully fitting the correct, integrated kit, and practising in F2? Maybe there's a comprehensive webpage or Youtube video that shows how it all fits together - in fact, how it works? I really am in the dark.


Thanks for reading, anyway.


P.S., I don't think those members who remain unshakeably loyal to the old-style pole that requires attendance at the mast, can help me by saying so. It isn't a question of showing my occasional crew how to do it better, it's a matter of just taking crew out of the equation.

10 years is a long time! I've seen twin poles on lots of Javelins now. Common on ospreys too.

Massive amount of string just to allow single handing though.

Buy an asymmetric?

Thanks for that...actually I have a couple of very different asymmetrics, as yet untried, but everything I read about Ospreys makes me think Proctor's original sailplan probably can't be beat.

You have a point though...all those singlehanders with kites, and not one of them symmetric.

A symm. gives the crew something more meaningful to do.  All depends on how involved your crew is in the whole sailing process.  My Fireball crew regretted his limited contribution in an assymetric.

I remember Fireballs ( last century!) having a mega extending tiller extension so the crew could steer from the wire and the helm could move forward pre windward mark to set the pole up.

Should generate some interesting onboard conversations!
