Spiros twins Osprey pics

   In response to Brambles question.Last century(!) I had a single spinnaker pole arrangement in a Fireball that was stowed vertically up the mast.
From memory there was a stainless steel gooseneck fitting at the normal spinnaker pole eye position and the pole up haul sheave was the length of the spinnaker pole up the mast, so this kept the pole tight against the mast when not in use and was used to stow the pole away.
There were 2 downhauls, one for each side. There was a free running ring on the spinnaker sheet. One end of the downhaul was attached to this ring, then ran freely through a sheave at the upper end of the pole and then to a cleat beside the mast.  Duplicated on the other side.
To launch the pole, release the uphaul, and pull the downhaul on the windward side. Then hoist the kite.

I do remember one race where the waves “discouraged” anybody from wanting to go forward and we were able to put our spinnaker up ok, the only boat in the fleet to do so.
The stainless steel gooseneck fitting was marginally strong enough.  It may be that a modern windsurfing universal joint rubber would do the job better

Hope this is of interest, it wasn’t that expensive to put together.

	Having sailed 505's up until 5 years ago, twin pole is the only way. I then changed to the Osprey, I spoke to many various Osprey people including Mark H and also Tim Rush. I went for the normal single pole, why? Well the Osprey has a much smaller kite then the 505 and also is slightly heavier so downwind you are not going anything like as deep and fast. Gybes on the 505 - sweet, but the twin poles generally on the Osprey cause more problems that they solve. I suggest you go onto the Osprey Face Book page and message Ben or Simon Hawkes - far nearer the front than me - who ran twin poles for about half a season and then took them off! They can give you their experiences on the Osprey. There are some big boys at the front of Ospreys, so don't worry about weight! The normal pole system lets you gybe comfortably (?) in really high winds, so is defo my choice and I believe the choice of most of the top end of the fleet. 505's tend to do windward leeward courses so go as low and fast as possible, Ospreys do Traingle/Sausage courses so demands are differant. Have fun.
