Just thought I'd share today's experience. I went for a sail off Sandy Bay this morning. There was a nice 15-20 knot Northerly. I hit the water, did two or three 1km runs. Just when I was starting to think about a river crossing.....crrraaack.
my rig imploded!

My mast had snapped a foot above the boom.

I was about a K off Sandy Bay Point upwind a bit.
Not good; browned wetsuit and unsailable gear. Wind freshening there was no way I could paddle or tow my gear across the wind to my launch point. I realised I'd have to paddle cross down wind to get ashore. Boom inserted through the front straps, longest bit of mast clamped into swivelled boom clamp. Harness through rear strap holding rolled up sail and short bit of mast, lose bits tied down; I started paddling....It took me an hour and a half to paddle ashore. Any further and I wouldn't have made it without help....which would have arrived eventually in the river. Better to self rescue though. Next time I'll have my phone in a waterproof case with me.
Today worked out fine. It could have been much worse if I didn't know what to do or got skewered by a piece of carbon fibre. I hope this shows how badly things can go wrong very quickly. Lesson....KNOW YOUR LIMITS and what to do if it all turns to S()!+
