One does wonder at the attractions of any kite on a small lake. Hence we sailed a Tasar. If I see a GP running dead down wind goose winged it makes the little kite seem pointless. However one early morning at Southport I remember a light tight reach the length of the lake. I flew the kite right on the edge, leach just  curling in, quick flick to correct. We were very light for the boat and we flew. That is when they feel so good.

OK so you are obviosly someone who sails an a big water with lots of space. I have sailed both but my home club is a river venue where space is limited and sometimes all we have is a beat and a run so a traditional kite works for us. RS 200's were originally built to be able to goosewing with a pole and short bowsprit and that worked well on the river but as usual the majority decided it was a waste of time (they mostly sailed on open water). One of the first eurocup events in Amsterdam had both styles going down the run with some straight lining with the pole and some banging the corners, and we still all arrived together at the leeward mark. Would have been different in a blow I am sure. I bet if you ask a fireball or merlin owner if they want to go asymetric the answer will be an emphatic no.

 

When they say you are too old you probably are, but do it anyway.

Merlin Owners are bottom feeding pond scum gone rotten with excess alcohol consumption, no one cares what they think, Fireballers however could be offered redemption, GP? just don't, tick I know you're winding me up go back to sleep.

Rivers yep, get that, but again if somebody got the assym thing sorted then otherwise excellent platforms like the X1 & 0 could have been spared the anachronism of their front end.

A lot of model yachts use a swing, or Balestron, rig where the boom carries on forward of the mast. The front of the boom swings out to windward as the main is eased. Normally they fly a jib off this forward bit of the boom, but you could fly a genny from it too. If the forward part of the boom was designed with the right flexibility it would bend off to leeward so that the tip was on the centreline when the boom was eased for a reach.

Look young Fuller, my nurse is instructed to wake me up when something important pops up. never miss an opportunity. Anachronistic front end ? Do I have that?

What we should do is drug GRF (I have spares) and stick him in a GP with the likes of those helms leading the GP fleet at Largs. Some of the best sailors in the country....and they CHOOSE to sail daft old symetric GP's.

On the river where I learned to sail, a bowsprit would get stuck in a bush if you got close enough to the bank to be out of the current.

Interesting concept, it would have to be the jib though wouldn't it.

My latest thinking was an L shaped pole that swivelled. So normal running it's pointing down, swivel it and it comes to weather.
As much as I praise that swivel pole of the Alto it can be a bloody mare and forget to centre it before a drop, particularly something a bit hectic like drop gybe harden up and you can get into a right muddle.

I'm trying to prepare myself for the up coming psyconslaught, it looks like we're getting the green chitty permission slips, Trevs had to fake a hernia, but it seems to be working...

I was thinking you could have the jib on the boom and the kite pole telescoping out from that. But I don't think the Icon/pyscon needs a trick kite system. I'm sure even a modest kite between 12-14m^2 will be just fine on a normal sprit.
It would need to be a short L to stop it hitting the water when pointing down?

The other major problem with this is that as soon as the kite filled the forward end would fall down to leeward and the jib would want to goosewing. Well, if I understand your system correctly anyway...
