Topic : Jib foot infront or behind the shoot?

What's the verdict from the pros?

Posted: 20/07/2016 13:52:56
Ian Holt boat, Diamond Smiles (named after a lyric from a Boom Town Rats song), had the jib attached in front of the shoot, it all so had a self tacking jib,hydrolic shrouds, and shrouds on trackes'.. When I bought the boat it all so had self launching poles, as did my first Merlin, Impulse....

In general the Jib tack is behind the chute, however Jon Turner has built his new boats with the jib tack on the bow in front of the chute.  I don't think that it makes too much of a difference, you will just have to ensure that the jib sheet is at the correct angle for the sail.

The advantage of the jib being further forward is that the overlap where the slot is, is reduced and therefore less likely to choke in breeze. If you get it right, there is a benefit to be had. However, this needs to be offset by the fact that you are causing a restriction around the chute with the jib when hoisting and lowering the kite.
For the definitive answer on the advantages read the following in this link
You will also need to make sure the jib clue is correct and jib car position in the right place. Those with fully adjustable in all directions would be fine. but those with fixed in one direction may have a problem
Enjoy ;)

 Developing this theme, is anyone currently putting a high rig on modern boats?

I'm not certain,but I think the old Diamond Smiles jib was high aspect.Another good reason to control the slot.

We considered it with the new boat (3763) to reduce drag across the sails, but the leverage due to extra height would not work for us. Would have gone nicely with the new style hatchet board, but felt we'd need to be 23+ stone to carry it and the area is slightly less subject to how you cut the sails ;) Surprised it has not been tried by one of the front teams (3764)

In terms of a Tall rig on a new boat Chris Haworth did this on 3663, which he has since sold.  Seemed to go ok.

It's standard practice on Scorpions to have the jib tack sited in front of the chute but, having sailed one last season, I found it a right pain compared to standard Merlin system.  There seemed to be a lot more friction when hoisting, especially when on port tack because of having to pull the spinnaker around the forestay.  Also, combined with the stuff luff system, we seemed to regularly find innovative ways of rigging the spinnaker wrong!  Whilst there might be slight advantage to having the wider slot, I feel it's not enough to justify the handling hassles.
