Does this look like it will work?

Not a great animation as it would take too long for me to do it in the CAD programme as I am not good at it. But anyway here is more or less what it will look like in action and should be a lot easier than the original version. Adding the angled base will also improve things.

I don't really want wheels as I am wanting something that doesn't really need secured once loaded.

Hence the locking wheels I mentioned.
Also, looking at your boot it doesn't look like you need to secure it

Used to transport air tanks this way in the past, never had one getting loose and those trips were about 400 km.

Never liked wheels on anything in the car, locked or otherwise. Too small a contact area for me to be happy about.
The boot is only ever like that when I am doing a boat around about in the harbour, the welder is normally tucked away in the workshop.
When I go and get a refill of Argon the boot is empty, or more or less anyway.

Can't you just do what I do [putting on my feeble OAP look ], ask the nice man at BOC if he'd mind giving me a hand lifting it in - he doesn't appear to have any problem doing it on his own.

No chance of that happening, the guy rolls it out and scans it then says seeya

Reg is only that end because of the way I need to lift as the top has the handles so once I get the bottom into the car I have good grip. The reg is a Nevoc style so no tools required, just hand tighten the nut, see pic. Putting it in the other way is no real hardship as it will be right at the rear passenger door.

The ambulance style trolley is a good enough idea but the cassies make wheeling anything with small wheels a nightmare and not really wanting things on wheels when in the car as it is much harder to secure.

I think my original drawing with the extended slot in the cylinder holder and an added slot in the arms may be the way to go. Bit more complex than a simple slide but it should be as easy to get in, if not easier and it has the benefit of being a contained unit so more or less secure, holding everything together and in one place once inside the car. The angled base is also something I will incorporate I think as that makes sense as well.

Do you intend to use the cylinder whilst it's horizontal in your boot or are you going to get it out to use ?

Also do you have to take the bottle and the welder out of the car and to the boat or can you always work from the car ?

I wasn't thinking of small wheels, I was thinking of 8 to 10" pneumatic ones that would allow you to trundle the bottle on site if required.

Yes, cylinder just horizontal in the car. I reverse the car to the edge of the pier and take the wire feed unit with me to the boat, there is a 10m interconnect, I then have the 8m push-pull from there so 18m from car in total.
