Pretty impressive. Does bending it that slowly put more or less pressure on it? What I am asking is basically if it might even manage to bend more in reality. Bending it sure goes a lot faster if the mast gets stuck when getting rinsed over a reef or rocks.

That is amazing

but yeah I wondered like masse as it does not bend that far in waves and breaks, (?) so is a fast bending but not as far just as fatal? Engineer peeps..?

It might bend that far in the lab but as soon as you attach the boom you're adding a point load which I'd expect to be a weak point causing it to load up and snap earlier.

I agree. We could see that in lab condition mast brake in upper 3/4 since all my mast broken are around the boom clamp.
I fact I have plenty bottom pieces broken but never the upper part.

A certain seabreezer was going up an escalator at Town Hall station with his two mast halves. On the way up they wedged between the escalator and the roof. He found out how far they could bend before they break. The rest of the station thought someone had fired a double-barrel shotgun.

Are VW manufacturing masts now? Looks great in testing but fails a lot earlier in the real world?
