On our Fireball the uphaul on the pole height is rope and works fine however the downhaul is elastic and unless the pole is raised to its maximum it gets pulled slightly up in the air when a gust hits which is taking some of the power away.  

Can anyone send photos or give tips on how it is best to rig this system so the pole can be raised and lowered so its secure and does not loose power?

Andrew,

I think most boats with a conventional pole (i.e. up/downhaul in the centre) have an elastic 'take-up' on the downhaul end. My downhaul (on a Severn composite) is rope until a bit aft of the mast heel, then changes to 5 or 6mm bungee which runs all the way to the back of the cockpit & then forward again to the front cross-member. The 'change-over' point provides a stopper to prevent the pole skying. I changed the bungee last winter 'cos it was tired even though I didn't have any skying issues. For best results the pole on a 'ball needs to be higher than you think.

Do you have a toughening patch on the jib luff? This is roughly the height range that the pole should cover - windier = up, lighter breezes = down.

Hope this is helpful.

Nick

Oops - forgot. The Spinnaker guy also helps to keep the pole under control via the twinning liners or reaching cleats.

Our downhaul is rope (at the end nearest to the pole) then a knot and a bobble where the rope ties to elastic, goes through the pulley at the side of the base of the mast and then really 'fierce' elastic to somewhere under the centreboard case I've never investigated.
The bobble and knot are at the maximum the pole ever needs to go up/out.
Try changing the elastic for some better stuff would be the first option.
