Full battened rig do we think that's a good idea? Wasn't that where the original Blaze went wrong?

Carbon battens, how flexible are they? Only seen two fully battened sails in the flesh, a Topaz tre' and a Enterprise cruise modified boat, both seemed to be constantly pumping the main sheet, must be a nightmare on a river.

By all accounts the original Blaze FB rig was 'orrible but the current Halo big rig is a fully battened square top jobbie, maybe that makes a difference?

Fully battened sails don't suffer from the top batten staying inverted like other sails. They can last a long time and give good performance when fairly old. I suspect it's harder to design a really good FB sail which is controllable over a good range of fullness. Perhaps more so with no shrouds, and hence spreaders? A lot will come down to the quality of design and develeopment, you want something that has been made to work properly, not a box-ticking exercise to get all the features which are currently in vogue. Copying what works best on a skiff may not be best for everyone. How much design and development actually happens that's not heavily constrained by class rules or working with legacy constaints like a given mast?

Eric-c . I totally agree with everything you said other than the first sentence.
We have a few supernovas at our club and I definitely seen them sailing with the bottom battens flipped though and the top two still inverted .

That doesn't tie in with my experience of various sails, some with single, Merlin like, long top battens, some like the Blaze with three full length battens, others like the Spice and 'nova with all full length battens and too many windsurfing rigs to count. I do take you point (and completely agree) that it all comes down to how well the sail is designed.

I expect there is no concept that can't be done wrong or defeated by the end user. But generally an FB sail should tend to make all the battens work together. Maybe this in not so much the case with a square top sail, where the top batten must be loaded a lot differently from the lower battens? Possibly this will become more of an issue as the sail ages, as the stresses on the sail are going to be higher near any batten which makes a big angle at the leach? Maybe it depends where 'sail longevity' and 'light air' are on the list of design goals. An inverted batten is a huisance in a dinghy, but we can rack the boat and sort it. Not so easy in a 40 foot leadmine where bigger roaches may be seen these days. Personally I like FB sails for the way they're easy to roll up and don't suffer so much abuse when not sailing.
