I'd appreciate some guidance on the above. I know my boat batteries are 6v and my van is 12v. What do I need to buy to charge from my fag lighter or from my desiel heater battery? Is it as easy as a converter from Amazon. Thanks.

It is that simple.
A converter from 12v to 7.5v is what you need.
Something like this:-
https://www.amazon.co.uk/DIGITEN-Industry-Waterproof-Converter-Regulator/dp/B018LF40LU/ref=pd_sbs_1/258-8038101-1627130?pd_rd_w=Mwv51&pf_rd_p=b3232d54-1e37-435b-b370-81046eef630a&pf_rd_r=F9G90EK14XPQGWP7ZCXW&pd_rd_r=3ade5b97-6b1b-437b-8a83-2828b6d14bbf&pd_rd_wg=hGLLK&pd_rd_i=B018LF40LU&psc=1
Do bear in mind it may flatten your vehicle battery, unless you have it running.
Or 12v solar panel, oh no we are 1000 miles too far north

I'm assuming your batteries are 6v but you use 2 batteries in series to power a 12v motor on the boat? If so, just connect them in series and charge from the 12v supply.
Unless you are planning on running the van the charge will be slow and you'll kill the van battery. Better off buying a few sets of batteries and charging them with a 230v charger when you're home.

Be aware that if you leave your battery connected to a fixed voltage supply too long you risk damage or at best reduced battery life.
Assuming the battery doesn't draw too much current and trip the converter you need to monitor the state of charge of your battery to avoid overcharging.
