Re: Storm Sailing Advice

There's one other factor you didn't touch on in your otherwise excellent post, FS:

There's one reliable way to indefinitely extend the period before the next killer set, and that's to dig out...

It's easy to overlook the importance of plenty of hot food, for sure.

When five people were doing the work of eight on one trip I was on, because the remainder were totally incapacitated, those...

Re: Storm Sailing Advice

Another way of looking at it is that those once-every-15 minute waves are the waves we tend to think of when we describe the conditions.

Which either means that (as I think I might have posted in...

Re: Storm Sailing Advice

I agree with Snowpetrel:

When a masthead anemometer is being subjected to the sort of seastate you get in strong winds, it seems to me the apparent 'wind run' past the mast could easily be 30%...

Re: Storm Sailing Advice

The thing that concerns me about the increasing tendency to apply the word "storm" to offshore scenarios whenever things get horrible (or even inconvenient) is not that it's dishonest (I don't think...

Re: Storm Sailing Advice

If you're talking about conditions in the context of that particular boat, sure thing. "Survival conditions" in a sailing dinghy might be F6, but that does not make it a "survival storm".

I seem to recall further up the thread someone defined survival storms as conditions where you were no longer able to head towards your desired destination.

I wasn't comfortable with that: to me...

Re: Storm Sailing Advice

One thing I put a lot of effort into is trying to avoid demoralising living conditions.

One of the main battlefronts in this effort, for me, is a remorseless war on water. Bilge water,...

Re: Storm Sailing Advice

It's a serious consideration: when things go 'tits-up', having extra hands aboard can flip from an asset to a liability.

It's much more of a problem than three or four decades ago, but even then...

Interesting idea, (pulling the cones 'inside out' - a la Baron Munchausen with the wolves...) - I had a similar idea, which I posted a year or two back, on the Attainable Adventure Cruising site.

I misled myself by imagining that you ran off to end up at Castlepoint, hence it must have been S sector. I'm guessing you were actually reaching up in the lee the of the Wairarapa coast, then?

Yes, great summary, Pelagic.

Has anyone mentioned restowing below, and securing abovedecks?

You make good sense, it seems to me.

Re: Storm Sailing Advice

I agree that it's often the declining phase of a serious blow which can be the most trouble.

One reason is the understandable reluctance (or inability, in the case of damage) to get sail back on...
