Rescue off Western Australia, crew ok, boat lost.

[Reefmagnet]

I'd only have to unscrew the depth sounder transducer out on mine to sink it. No tools required.

Wow, I think you may have been living in a fool’s paradise. There are a number of components that can sink a sailing boat with only the slightest intelligently applied force.

In my case I’d either pull the PSS seal boot, or cut the engine cooling pipe, or the water maker feed or the toilet feed.

30 seconds.

Max.

Oh heck, yeah that one too. Actually, it’s a bit of a struggle to NOT sink the boat with those puppies. At least it feels like it when you swap it out for cleaning.

In fairness, there’s some kind of valve that automatically closes on mine when I pull it out, but it leaks something shocking and I can never get the holding plug back in fast enough.

IIRC, John Sanders came to grief only 5 nm off the coast where the coast line is an extended line of steep cliffs. Also disturbed seas but for a different reason.

On balance, it seems a part of the world where it pays to pay particular attention to the weather, particularly as it pertains to wave action.

On that point.. any areas I should be worried about when approaching Tassie?

The winter weather is generally not too bad that far N on the WA coast.

my missus sent our flapper valve to the bottom the first time she had a crack at swapping it out with the dummy plug. And at about 2 feet below the water line, the water ingress is quite brisk, let me tell you!

I met a couple who lost their shaft and prop while sailing. The first they knew about was when the water was over the floorboards! They actually managed to save their yacht.
I reckon a sharp knife would scuttle just about every yacht I have surveyed.

For sure, Matt... the hostile natives, especially around the D'Entrecasteaux channel are pretty damn dangerous.

Seriously, the whole west coast can be exposed and treacherous, with really only two places to shelter, and only one of them accessible in harsh wx. I think we've already discussed this!

regarding scuttling a boat, i'm not sure any of the suggestions made would work on a catamaran...

our engines have watertight bulkheads that go aove the flood level
we only have a speed sensor in one hull
lastly even if both hulls are flooded, we are not desperately trying to keep 5mt of lead afloat

perhaps we would sink (i'm definitely not going to try) but i'm not sure...

cheers,

I reckon a sharp sneeze would have scuttled one or two I looked at when shopping for this boat.

Well, I feel a little better about mine now... but... err... how the heck did she manage that? (Asking so I don’t so the same.)

Yeah, I seem to remember some dire stuff about the westerly approach...

Mighta suppressed it.

I am not sure I would say that "the continental shelf is a relatively narrow" at 90 nm. Off Sydney it is only 10 or so nm.

Okay, everyone, all this talk about scuttling is making me nauseous...

Please let's not talk about (potentially) sinking our boats!

Sydney is a special case - always has been

You make fair point though, I guess it all relative. Further north, the shelf gets gets very wide and remains extensive right across the top of Oz.
