fstbttms,

Funny dat. The most common source of foreign species is the ships that come in, and yachties wiping their boats' bottoms' would not have introduced them.

However, the ships bring in goods, and pay in lots to the economy; in the present political climate there, they are, imho, unlikely to be investigated or dissuaded in any way.

Re: In-water Hull Cleaning Banned In Vanuatu

I think ships are supposed to run any ballast water through their engine cooling systems to kill marine life before they dump it. I wonder how many of them actually bother to do so?

Where did this come from? The water run through the heat exchanger doesn’t really get hot.

Wonder how they plan to police this ban?

Simply, they take a photo of the boat on arrival, and if they see a few days later (in clear water) that the hull is clean(er), they will approach you and ask questions.
Ask me how I know this (although it was not Vanuatu).

100% untrue. Sailing vessels moving from port to port are absolutely a source of invasive species transportation.

When we went to Vanuatu, customs didn't have a boat. There was no inspection of our boat whatsoever. We had to go ashore and catch taxis to the customs and immigration offices.

In theory, you are correct. However, the practice is different.

The reasons for this have to do with how people get to Vanuatu with their cruising boats. Put simply, the places from where they would be coming, are places where it is very easy to leave from with a clean bottom. None of the cruisers wants to put up with the slowness of a dirty bottom on passage, and they'll either have fresh paint, or have wiped their boat bottom before they left. It is purely geographical, and it is not the marina bound boats that form your business. It is a different situation.

Don't recall where I read/heard/saw this and it may be a local rule for ships using Australian ports. You northern hemisphere folk have pretty well spread every invasive species already whereas us fastidious southern hemisphere types have kept our seas pretty pristine.

The water does not have to get very hot to kill the target species apparently (For example, coral die-off starts to occur at only a few degrees above normal sea temperature)

So that's why Vanuatu banned in-water hull cleaning, because all the cruisers were coming in with clean bottoms?

No they likely banned bottom cleaning because some started a campaign about how invasive species were found, and in order to check the “we did something” block they banned bottom cleaning.
That or someone is going to start a business of short hauls and pressure washing?

Oh the humanity! All those filthy bottomed boats lugging about filthy species. Ban all boats and require all sailors to report to the nearest pub promptly at 9 am each day. Problem solved:_)

Re: In-water Hull Cleaning Banned In Vanuatu

Well, fstbttms, et al,

What I have written is based on a combination of my experience in that area, as well as reading. It is the ships' discharging of contaminated bilge water that has been the cause in Vanuatu, as closely as I have been able to determine.

In Australia, by comparison, there is some evidence to indicate that zebra mussel infestation was transmitted by yachts.
