Yes R&J sail. I'm not sure if the sail was designed for the mast. But they are both similar in age! The boom is free floating at the goose neck. I've always been unsure about that. it sounds like its something to try. Because as you relieve the pressure on the sheet the boom does move forward and roll around the mast. Having a rollock would help keep the boom from doing this and help keep the bottom of the soft luff pocket from collapsing forward. Good idea.

There is no downhaul. Only a few yachts seem to run a downhaul system from what I've seen. This is normally part of the sheeting system, so as you sheet in you apply more downhaul.

The current battens are fibreglass with a slight taper. They are the white ridged style of batten. In section they look like a cross.

May be usful info .(from NZ Sandpaper mag)


Planing class 5 Battens:
Although the object of your aerofoil is a
maximum camber at around 40%,
because of the mast and mast pocket the
battens need to be shaped slightly differently.
I recommend that the shortest top
batten should have it's maximum camber
at 22% back and the longest at 35% with
the rest arranged logically in between.
Some people prefer 25% for all battens
and the fact that both methods give good
results shows that what is most important
is that you have a uniform shape over the
whole length of the sail. Mixing stiff and
soft battens with the max. camber at vary
-ing amounts is the worst of all worlds.
There need be no magic skill to planing
class 5 battens so long as you are
methodical and prepared to take quite a
long time about it.

thanks for that very helpful!

I would say that it varies depending on the center of balance of the yacht, the center of effort of the sail and the center of lateral resistance of the yacht. My personal view is that the center of lateral resistance is a nightmare to calculate. But is close enough to the center of balance to make no odds. So my answer to your question would be that the mast post position depends on the the design of the yacht, sail and the weight of the pilot. IMO which isn't worth a dime!

I thought that the Plumes and the air tracks would have the mast post in a designed position as they are production yachts?
What sail is the best performer at this time. The only sail maker that I can find in your part of the world is R@J.

True. But I think both of those yacht designs have moveable cockpit shells.
R&J and I think Gosslings in the UK.

Not 100% but that looks like the Class 5 yacht that cleaned up at Brean's last regatta. Different / new sails though. So certainly a good landyachter is involved.
