Taking a polishing tool to Spain. Worthwhile?

Does it really need T-cutting regularly? My last boat (24 years old when I sold) only got a wash down with sudsy water and "creme cleaner", followed by liquid polish and then liquid wax, all hand applied. Kept it looking good.
 
Lift out and antifouling due in March ( Burriana near Valencia).
I usually just Tcut the hull by hand and then protect with a few coats of wax. The 'just' T cutting is now becoming a problem due to old age!!
Normall practice was to wash off with detergent then 'T cut' the hull with plenty of hard elbow grease and then I usually had to give it a second go with the T cut.
Apart from aching arms I find my ancient hands crack and become very sore!
This time I am considering buying and taking out a polishing tool. I will appreciate advice on the tool I need, the grade of polish I need and techniques for a beginner!
We currently have a store on site so I guess I could leave it there as its not the sort of tool we would want to keep on board.
I'm not looking for a 'super dooper' professional tool but rather a decent DIY user type.
Advice appreciated as ever!
Dont need to Tcut every time. All that will do is reduce the gel coat. My missus just washes and then applies a coat of Autoglym. It gets rid if grime and leaves a fabulous shiny finish.

We usually wash off the hull to clear wax and grime, I then select an unobtrusive small area and give it the T cutting experience, if it looks a lot better then the whole lot gets done!
To be honest we could 'go' 2 years before there was significant 'chalking' so just wash and wax may be ok this year ( or alternate sides each year!?)
 
Is the 'liquid polish' an abrasive type polish ? just what does it do?

For years, I've used Meguiars 45 Boat/RV Polish, which is a liquid. It's very slightly abrasive (hardly at all). It rubs on easily and polishes off easily by hand. I do 2 coats of that, followed by 2 coats of Meguiars 56 Pure Wax - again, a liquid which rubs on easily and polishes off easily by hand. I've followed that regime every 2 years for ages; every 2 years because I only lift the boat for antifouling every 2 years, it spends the rest of the time in the water. This pic shows my previous boat at 24 years old...

I bought a Silverline Polisher, similar to above, a few years ago for annual shine up. Still going strong and very effective.
Can get a bit heavy after an hour or so.
Can be sourced from many outlets from ebay to Screwfix etc.
