depends on your rig as to whether or not it would come down more than 60-65. what I'm saying is that if the windspeed doubles(or more) inthe blink of an eye as is common when microbursts occur that it puts massive stress on the rig, a safe amount of sail for 40 knots isn't safe is the windspeed...
fair enough on "without sails being up", to many variables to really make such a broad/general statement.
though I would hazard to say if there's a weak point or fault in a vessels standing rigging the violent knockdown that a microburst can cause is absolutely enough to cause standing rigging...
guess 3 times wasn't enough, just because you see it and know what it is, doesn't mean you have enough time to get out of it's way. there we go, that 4 times. oh and for the record I have taken a class. I'm USCG licensed and have been run through the USCG meteorology course, weather routing...
lets just say that it was noticed and recognized for what it was. that doesn't mean the crew had ample time to respond and again, I'll repeat myself, if it was close, as in within a few miles there's not a damn thing they could have done to get out of it's way.
honestly detecting squalls is one thing but being able to discern which is a microburst is a separate issue entirely. and even so, if you're in the path of a squall cranking along at 70kts you're going to be hard pressed to get out of it's way . it was discussed in another thread that even a...
after reading part 1. it sounds like a textbook microburst. scary shit. microburst can bring a rig down without any sails up at all. not much you can do about it.
