However on this point.
If you have had a mast fall down five or six times, statistically compared to other dinghy sailors that would point overwhelmingly to operator error on your part. 


Well it's been over two or three different boats, the EPS came down on the lake when a fastpin twisted out of one side of the chain plate, have still got the bent out of shape chain plate to prove it.

The Farr 1st time was a shackle that came suppled brand new, nothing I did. 2nd time might have been a bit my fault not saying why, third time was another fast pin on the lee side (I was out on the wire we all went in the water together)

The Hybrid/Fireblade was a fast pin (why do I never learn)1st time, then a bottle screw but I managed to get ashore before it completely fell down.

I've had boats that nothing (like the mast falling down) went wrong, the Musto, L3K, RS500, Alto, RS100, and the Solution, Solo, Minisprint have all been OK.

Here this is the sort of thing I would have liked to see applied to those shrouds, ignore the fact the illustration is on shoes in this video, the Boa system has been used on lots of applications from Snowboard boots to wind and kite harnesses, as a use for micro adjustment on the fly it would work on shrouds.

iGRF @2.49.
I take it back; you have obviously been a statistical outlier.

@Graeme, if you’re having fast pin failures then they’re not seated properly, or the tiny spring behind the tiny ball bearing retainer isn’t working, allowing the pin to creep out. Anything with moving parts needs maintenance, especially if it’s exposed to salt water.

I distrust fast pins where rig tension is low, boats with slack rigs and such like. I have a couple and decided to use them on my dyneema lowers for ease of adjustment, and I decided they were less critical than on the shrouds or forestay so it would be a safe place try them out. I had a protracted capsize on Sunday and during the process of recovering one of the fast pins came partially out releasing the lower and preventing me from sailing on. I'll be reverting to clevis pins and keyrings this weekend.

I have the nice shroud adjusters which don't completely let go of the shroud when the fast pin is out.
 
But I also cover the adjusters with some neoprene sleeves, you can also use push bike inner tube.  It's pretty difficult to get the fastpin out with the cover in place. Maybe some sort of rigid cover would lock the pin in place?   The risk is perhaps highest when people help pull boats up the beach?

I have considered that but sticking bike inner tube over the shroud adjusters sort of defeats the 'easy to adjust' element. That said they are pretty much impossible to adjust on the water anyway...

I always used stainless steel bolts with nyloc nuts on the Enterprise, no need for rapid adjust on a 20 acre lake, didn't  stop the Starboard shroud ripping half the deck and a big patch of the hull off, totally destroying the boat, not the fault of bolts though. the strip of hardwood under the gunnel had quietly rotted away, was quite spectacular.

Is there not a solution that is based in a drop nose pin with some plastic part that fits between the shroud adjuster and the drop nose so the drop nose can’t flip up. (Obviously trailer drop nose pins have a locking steps in the drop nose but with the random widths of things being pinned on boats this less likely to work) 

Advantages
> no separate rings
> sheer area is full 6mm not 6mm minus area of fast pin mechanics 

PS - I use a 40 year old fast on my downhaul, never failed. I think it is critical to have a good gap between the side of the shroud plate and the locking pin to avoid any longitudinal stress on the locking pip

I think the point about fast pins is that they're only fast if used without any additional safety precautions...
