Full Hyde sails.
Comments above certainly tallies with my experiences.
Difficult to reconcile with the title of the OP
One of which was a one-design racing dinghy (I had 5 over the years all but one new), sails from boat builders only. Over those years Hyde cycled thru as the "selected suppliers". They didn't last long before builder changed sailmakers again (citing "inconsistency", I seem to recall?). However, this limited number of well made, yet fuller cut Hyde sails are now sought after by some very capable helms for use in certain conditions where it is clear they offer a significant advantage (but are, of course, still class legal)...more power/drive.
Was not at all impressed with my BRe Hyde jib, almost new and barely used. Very full, impossible to flatten and just set badly.
I got a new semi-battened (non furling) race jib made by a local guy, who is now a sailmaker on the NZ Americas Cup team and so is currently unavailable. Sorry GW! Once he gets back, I worry he'll be unaffordable!
3 battens, full length at top. Leech n foot tension lines, dyneema luff rope (not wire) with downhauler/jib cunningham. About 15% larger than standard, to max fore triangle dimensions. It needed towable jib sheet cars really...but not too onerous to move cars on a BRe. Drill a few more pin stop positions too.
This sail transformed the boat upwind, but a bit of a pita to rig/remove. I generally used to go alongside a pontoon to remove the Hyde and furler, then rig the race sail. This sail was sold with the boat.
Main was acceptable, but see below re crappy battens.
I'd planned to go for a similar new "race" BRe mizzen (as per Salcombe Yawl), but boat sold.
My original BC 26 Hyde furler jib is surprisingly good. Just now needing repairs to UV strips.
Main v much less so. Until I saw the 2013 sea trials pics, I thought it was probably just age/use/iffy storage at almost 10 yo. Battens APPALLING "contract" rubbish, same as those on BRe. Barely capable of supporting this larger sail section/cloth weight.
However, even from pics at build, this main never looked good to me.
New main (sailmaker, see above) v v much better, also with tapered epoxy battens. Not cheap but money well spent, so I tell my wife...
I've been after the same sailmaker for an asymmetric (and ideally a code 0) as I can't find/afford similar product quality and top rate service from the alternatives hereabouts.
No chance!
