Hazard to Nav ?

[catty]

I was updating my charts yesterday and came across this one.
Can anyone identify this cat.

Here's an idea - if you want information ask the people with the information:

For further information about this notice, please contact:
The Gladstone Regional Harbour Master’s office on 07 4973 1200

Tell me catty - have you updated all your Moreton Bay and Brisbane River charts with all the sunken monos and power boats.

And FYI - that notice has been cancelled, the salvage was succesful.

Well - I saw three - either personally or on TV. I understand that there more and I also saw a number of power boats get wrecked (all on TV).

Me thinks that you thinks wrong. Catty seemed to be well on top of his chart marking duties for an area 400 mile away - just wanted to check he was on top of his chart marking duties closer to home.

It doesn't seem to be a good time for a cat vs. mono-hull "dog fight." Besides, wasn't this mostly a flood/current tragedy where boats were torn from their moorings rather than waves and winds? Wouldn't steel vs. plastic vs. wood hull construction, mooring methods, taking-steps-to-take-one's-boat-out-of-danger, etc. discussions be more appropriate?

Absolutely - the OP was worried about a hazard to navigation 400 miles away that has been quickly salvaged, I just wanted him to be aware of ones closer to home.

The issue with many wasnt so much that they were ripped from their moorings, in many cases they were firmly attached to pontoons that simply floated off the poles, Indeed a number of small power boats floated downstream firmly attached and ended up being able to be recovered with relatively minor damage. Many were not so lucky.

OK. Perhaps marinas will use taller poles when they rebuild, like this:

They will need to be taller than that - all the marinas outside the river were okay and indeed even a marina at the river mouth was fine. (rivergate)

Many of the floating pontoons may have come from well upstream where the river heights were possibly 10 meters higher than usual. For example there were many pontoons on the river at Jindalee, usual river height here is around two metres - give or take, on Friday well after the peak (which was thursday) it was well above eight metres, I cant access the historical data back beyond Friday at the moment but we can assume that the poles would need to be fairly tall based on that data alone.

Even then I am not sure if the poles would take the drag etc and not give way, there are a number of poles in the river where pontoons used to be that are bent over. Its going to be interesting to see what the Commission of Inquiry says about that along with many many many other issues.

Of course this is a once in 100 year event and of course we all said that in 1974 as well.

When the marina at Hamilton Is on the Great barrier Reef was built it had tall poles to withstand the tidal surge during a cyclone. But the owner of the resort saw them and was horrified at how ugly they looked. He had the tops cut off. The resort has since been sold a couple of times.
The Brisbane floods are being called a "100 year event". People are often prepared to play Russian Roulette when they think it won't happen to them or it won't happen again.

I heard it was a seawind 1000. Is this correct?

[Factor]

Where did you hear that from? Given that it was 9.1 meters long I suspect not. When I rang Gladstone the lady on the end of the phone at the harbour masters office indicated she thought it wasa power boat but she wasnt sure.

Whats the source of your information.

I also note that the Notice to Mariners was cancelled many days before you posted here.

Seems the boat has been salvaged, the hazard is gone, and the fishing expedition is over.......

We've just deleted several posts from this thread as they are off topic mono versus multi.
Please keep this thread on topic.

Notice to mariners 215 notes a sunken Yacht between Fisgherman and Mud Islands, 27-21.181 and 153-13.244. This one is definately worth noting on charts.

Anyone know what happened? (
