My boat has a TMC electric heads and I'm looking for a wrap around holding tank as per the photo below.
Anyone know the brand or where you can get these from?

Thanks for the lead and educating me on buffer tanks. I may go with a tek 40L vertical waste tank instead.

It's an Osculati Black Water Tank 26L

Mfg part number appears to be 50.144.25

A company called Australian Boating Supplies claims a relationship with them but doesn't list the item in stock.

Good to have a bulhead mounted above WL tank for easy offshore discharge.

I have a Vetus 60 litre. Its got a nice shape V bottom and outlet for a complete pump out.

Size depends on POB & how many days you expect between emptying.

Thank you for the information above. I have some alternatives and I will go with whatever I can make fit. I agree a gravity waste offshore is the way to go if I can make it work.
