220v to 110v. Where do I start?

The other would power the Air Conditioner

Anything else requiring AC on the boat could be run off the inverter

Very high level and of course code should be followed.

OR,
Plug an extension cord into the dock AC plug
Bring the cord into the boat and attach it to a breaker then a GFI box and then to a 240v- 120v transformer which supplies 120v output.
Connect the transformer's 120v output to the boat's shorepower connection.
No other changes needed, unless you have a 120v item onboard which is sensitive to the 50/60 cycle issue.

Being able to use the power tools currently on the boat is my dream. A cheap converter that allows me to use the 110v power tools feel like a fantasy.

It's no fantasy! Just get a transformer to allow the 240v shore power to be transformed to 110 for the boat, then run a long extension cord from one of the boat's 110 outlets down to the boatyard where you plug in your existing power tools.

We did this many times.

The marina in Malaysia that she will be at gets very little breeze so I'll be running an air conditioner, plus other electronics for the year. After that year, I plan to cruise for 2 years in the pacific living on the hook the whole time. Currently, there are many 110v power tools aboard such as grinders, drills, sanders, etc. that I'd like to use. My questions are:

What are your initial thoughts?

Should I get a step down transformer. If so, where do I start?

Should I rewire her to take 220v? Thoughts on power tools?

Bring on the wisdom

In Langkawi Malaysia if you go to Kuah there is an electric supply store that is listed in the cruisers guide. They have or can get suitable step down transformers. I bought a 5000 watt transformer there a few years back
