From AI, Western Australia hosts one of the largest humpback whale migrations in the world, with over 45,000 whales traveling up to 13,000 kilometers from Antarctica to the tropical Kimberley region and back<
My guess is that a whale took out his saildrive in the middle of the night.

He is lucky to have been rescued out there.

From AI.
Nine tonnes of scrap lead in Australia is worth approximately $9,000 to $22,500 AUD based on current local scrap market rates of $1.00 to $2.50 AUD per kilogram ($1,000 to $2,500 AUD per tonne).

$9,000 to $22,500 AUD is a big range but it doesn't come close to the cost of removal and decommissioning.

My mate is the pres of a men's shed.
They are fantastic.
I would love to have access to one.

A couple of Dicks discussing the Oyster capsize.
I'm not in tune with them though.
Forward sonar????
Shoes??

Would you buy a Chinese navigation software system if it was available?
There probably are systems that the Chinese merchant and fishing fleets are using, however the Chinese have not yet entered the lower end of the market (us).
We had no problem buying an Italian system (early Navionics), so would we flinch at a Chinese product.
There are a couple of Youtube videos that led me to ponder this.
One was an introduction to Open Cpn open source navigation system. In that video they charted the course of Navionics from a reasonably priced user friendly Italian product that became truly “commercialized”. My subscription ran out a month ago, so I know exactly want commercialization means in this case, so does everyone else who is hit with the, “locked out, pay to get back in” model.


The second video was an analysis on why Chinese cars have become so popular in China.
Now outselling and being more desirable than premium German cars.
Sales of the name brand German cars (Audi, Porsche, VW) have halved in the last 4 years.


The commentator starts with the electric seat warmer in a BMW. Every car is fitted with a seat warmer, but they are not switched on. To use “your” seat warmer you need to pay $17 US per month.
Not $17.
Not $17 a year.
$17 a month (that is a quote from the video)
So, you buy a car, you buy a seat warmer and then you have to pay the car company to use it.
I don't know about you, but that sounds greedy and very similar to the Navionics model.

Every car in China now comes with self driving features that are fitted to the car and no subscription is paid by the owner of that car.

I know there has been concern about the Chinese fitting a kill switch to their systems (like the Americans have fitted to their exported military systems (subs?)). However Navionics is already fitted with such a system that activates every year, on the dot.

If a Chinese company came along with a model that broke Navionics (capture ) model, would you buy it?

If you have an opinion, please take the time to watch the videos, so you know where I am coming from.

RE one part of one blade left due to no anode on shaft,
Ouch!!
Check the engine anode.
Very simple and inexpensive replacement.
Best of luck on the prop.

All tied up,
The port is full of sheltering trawlers.
BUT
This will interfere with my plan for a night sail to catch the meteor shower.
Hope we will have nice clear skies after the typhoon passes.
I did a night hike to the top of a mountain here with a good friend 30 years ago for the same meteor shower
He was supposed to come up from Tokyo for the night sail,but trains look to be out.
Sorry Northern Hemisphere only! The best time to see the Perseid meteor shower is during its peak on the night of August 12, through to early morning August 13.

The Ultimate Viewing Window
Peak Hours: The absolute best viewing window is between midnight and the pre-dawn hours on the morning of August 13. During this time, the constellation Perseus (the shower's radiant point) climbs higher into the northeastern sky, significantly increasing the number of visible meteors.
Secondary Window: The night of August 11 into the morning of August 12 will also offer an exceptional display, as the shower builds up steadily to its peak.

Thank for thought Kinora.
All fine here. I am far away from the quake zone.

RE: kept telling me to go to port despite that being off the lead lights (fourth mistake).
If in doubt SPEAK UP.
There is nothing worse than hearing, "I thought that would happen," after the event.

From about 45 minutes in (up till then it is well worth watching) he gives a walk through of a really well thought out boat.

RE: The electrical tape could insulate the prop shaft from the oxygen it needs to prevent corrosion.

Prop speed is a silicone compound and it would insulate the stainless steel much better than a few wraps of plastic electrical tape.
I experimented with galvanizing spay can paint on my prop and shaft a few years ago and posted here.Not a success!!
Serb did his long term anti-foul experiment.
Now it's Jule's time to give tape a go and let us know,
What do we have to lose?

RE;

what are you guys using to clean up the prop which does a good but relatively quick job but doesn't chew into and thin out the blades too much? Flapper wheel on a drill?

I use a cheap brass wire wheel in a drill. Finish of by hand with emery paper
