Nice pictures of a nice looking boat, you almost caught the moment of the break. There's a challenge for the photographers.

Mine broke at the spreaders. hell of a bang. Did you damage the sail - mine survived. We were sailing with a very full nylon spinnaker in the North sea waves at the time.

your mast looked stiff sideways upwind, but despite a shed load of down-haul you were getting next to no mast bend. When you rig the new mast[$$$$$$$$!]check your spreader rake[50mm on the euro sails], this will help flatten that very full mainsail upwind.

The more you ease the main downwind the more the mast bends and the fuller the main and spinny get, then the more you have to bear off. Bit of a downward spiral. Until bang. It cost me a lot of money to figure this out!

Hope that you get the boat sorted soon. looks like a good sailing spot there.
