trying to get used to sailing with a P&B main instead of the previous North (all 2nd hand). I was wondering if what I notice in the trim is right, or just me making a mess of things.
With the North main I could bend the mast and the sail would go almost entirely flat…hard to see any camber at all. The sail seemed to flatten out evenly.
With the P&B main, I can bend the mast and the sail gets flatter very evenly, but still with quite visible depth. Then if I bend the mast beyond that point the shape goes all to hell. I mean a god awful mess. Now since the P&B sets in a nice shape until that point I tend to assume that it’s a difference in cut and style.
Would that make sense – that there’s more broadseaming camber in the P&B than in the North? And that you can’t overbend a mast with a sail that’s got broadseam fullness without the shape going all to hell?

Well, ok, looks like nobody else has any answers, but I have used both types, so here goes.
Assuming that the sails were cut for the same mast bend, there will still be differences where and when the sail goes ‘out of kilter’, but they should be small, and you should be able to control the sail shape by Cunningham and outhaul/inhaul.
From sailing with both types myself, I found the North to be much easier to control the shape than the P&B. Being more ‘gradual’ in shape change as the controls came on.
All sails reach a point when actually sailing with them, when, if over-sheeted or over anything-ed they just seem to go ‘off’ and loose power, even if the shape still looks good. Hope that helps.

It can’t be easy trying to tune up without a lot of other boats to compare with Hugh. With the Nationals in Pwllheli a short ferry crossing from Dublin and about an hour’s journey from Holyhead why not have a trip over. There’ll be plenty of technicians to give you some advice with the rig and a load of sailmakers there to try and sell you a sail!17th June 2016 at 11:38am #8809KazrobParticipant
It might just simply be that North have much more experience putting together the correct cloth, luff curve and broadseaming for a particular mast on a rig like the OK from all their Finn and Europe development over the years. P&B perhaps have less depth of experience in that field and perhaps don’t have that same knowledge of how all three interact.21st June 2016 at 2:49pm #8810hughsheehyParticipant
I’m looking at how to get to Wales for the UK Nats – it’d be great to go.
On sails, I think I’m likely to go and buy a replacement North (or take a flyer on a Quantum) before the event so I’m not getting used to it on the day and not sailing with my old rags. On sail choice, I’ve sailed with North, P&B and a older Gale&Rimington (still little used and crispy).
The G&R was the loosest leech, the P&B the most closed, the North in between and clearly the fastest around a course. The North was made-to-measure, but a good Finn sailor had a look and the other two weren’t far off. Overall it feels like the P&B is better for flat water, made to point, but not as fast upwind in any kind of chop when the leech feels too closed too often. The G&R is lovely in a real blow, particularly downwind when it’s smoooooth. The North seems really good in almost every condition. Perhaps just the advantage of really made-to-measure over nearly-a-good-match, but you work with what you’ve got.
