Erk - that WAS a big one - massive roaring crash and Iguacu falls cascading off the coachroof, poor old Berri shuddering and shaking herself and off again. We have the main up with the 3rd reef and it's really way too much but this is supposed to blow out - like 6 hours ago...And we are continually pushed south - got to get as far north as possible in the next break.
A bit of reality TV for anyone else who might be thinking of following:
first - the Grib files always underestimate the maximum wind in any low pressure system - if you double the grib forecast you are in the ballpark
second - if you have one, a trisail is the way to go but to be any use, it has to be the easiest sail in the boat to hoist. Invariably, it is the hardest because nobody ever uses it. Get a separate track fitted for it on the mast with its own halyard, exiting just above the top of the track, and take the track down to deck level - then you can leave the trisail in the track, in a bag but ready for instant deployment. For various reasons, I could not get the track down to the deck in Berri so we can't do that and the tri doesn't get used as often as it should. The third reef is way too big for most of these weather systems.
third - get a good quality aneroid barometer, calibrate it, fit it where it is both highly visible and safe from accidental bashing and use it. It can place you on the grib file more or less and it is the best indicator you have apart from looking out of the window as to what is about to happen to you. A digital barometer in your wrist watch or on the bulkhead is ok as backup but it needs batteries or some sort of power supply and is subject to other damage like salt water ingress.
Apologies if that's all a bit condescending - but I think it needs to be said occasionally.
Seems the last big wave wrote off the GPS aerial - filled it with water. Damn! Have backup, can travel but a bummer.
