For the audience Badenoch was talking too, Tory members, this makes perfect sense. The purpose of state benefits is to make the well off even richer, as they will use it to invest, or something. Not to go to the feckless poor, who will just waste it on their feral children, or fags, booze and scratch cards. Being in government means they can rebalance the tax and benefits system in their own favour.

You asked, so, I'll say it. This is a stupid idea. A boating neighbour had exactly the same issue and did what you are proposing. The arrangement was a hard BSS fail on numerous points, including, but not limited to the tank not being properly held down, filling allowing spillages into the boat, venting system not being above the filler and fuel lines not being properly supported. She had to get the bug situation sorted and the supply reinstated to pass a re-exam. There are BSS options for removable tanks for outboards, but these don't apply to a fixed inboard engine. On a practical note, every time you run out of diesel cruising and change cans, either with use, or the pipe becoming dislodged, the engine diesel system will need bleeding. Depending on the engine, this can be easy, or very time consuming. If you happen to be on a river, approaching a weir, when this happens, what then? If the open can falls over over and dumps the contents in the bilge and a bilge pump then throws it overboard, you will not be popular with your fellow boaters, CaRT, or the Environment Agency.
