When it comes to moving fuel from a Jerry Can into the deck fill on a sailboat, the "rattle ball syphon" is the
best idea I have ever found. I bought one over a decade ago at a local chandlers and they still sell 'em.
I asked Mr Google about it and quickly found this link:

The fuel can stays upright, no (or very little from a last dribble from the hose when done) fuel is spilled. My back is just not up to lifting and pouring from a full five gallon container of diesel any more.
You do have to coil up the empty hose-and-valve and store in something like a larger zip-lock bag. I store this and the little plastic bottle of diesel bug killer in one place in a stern storage locker.
I would guess that most of the cruisers in our club have one of these on board.
