Default Appropriate procedure for connecting and disconnecting from Shore Power

My boat is a 110v in Australia, so our shore power is 240V. That said my boat has a converter for converting the 240v to 110v (signed off to code by a marine electrician), so I don't think it will affect my procedure, just as an FYI.

I understand the general procedure is:

Connecting Shore Power
1. Ensure shore breaker is "Off"
2. Ensure boat breaker is "Off"
3. Connect cord to boat outlet
4. Connect cord to shore outlet
5. Flip shore breaker to "On"
6. Flip boat breaker to "On"
7. Check for Reverse Polarity

Disconnecting from Shore Power

1. Turn off breaker on shore
2. Turn off breaker on boat
3. Remove cord from boat outlet
4. Remove cord from short outlet

Is this sufficient, or (as I suspect) there is more to it? For example:

In the attached picture, should I be turning the silver dial in the bottom right hand corner to "Off" and the Shore Power 1 switch in the top left hand corner to off? If so, I assume I do that after checking for reverse polarity (step 7)?

Yes the converter will do as you say. Your procedure for connecting is correct. Regarding you disconnecting procedure #1 and 2 should be reversed as the load side should be unpowered first. Additionally #3 and 4 should be reversed as leaving the cord connected to the shore power adds risk if you forgot to turn off the shore power breaker. If the cord were to get dropped into the water a shock hazard could occur.

Do I need to do anything with the switches I mentioned?

First turn off all load breakers then the shore power breaker and finally the shore/generator switch off.

Why the shore power breaker before the shore/gen switch?

I guess you could do either but with the main breaker off there is no load which is the important thing to do. One reason to do shore power first is if you are switching to generator I prefer to de-energize the shore power first.

The Shore/Gen switch is cutting all power to the panel.

The Shore #1 and Shore #2 breaker are somewhat mislabelled. They would apply whether you were drawing from shore or generator, theoretically. These are really the breaker for that respective side of the panel.

The breakers themselves are for the individual circuits.

I would shut off devices, then shut of individual breakers, then shut off the each of the bank of the panel (shore #1 and Shore #2), then shut the main feed (shore/Off/Generator) to Off

If for nothing else, than when you replug back in again, you're going to dump a full load on the individual circuits in the panel when you plug back in again.

Instead do it in reverse order. Once the cable is plugged in and the breaker on the shore power stanchion is on, power on the (Shore/Off/Gen), then power each bank of the panel (shore #1 and Shore#2), then the individual circuits in each bank.
