I prefer the plastic orange juice jug cut diagonally so the handle remains.

These one gal. jugs are much heavier than the milk jugs and surprisingly
they don't seem to deteriorate in the sun.. I get several years out of one,
if no one 'borrows' it and doesn't return it (call it stealing if you want).

When I was living aboard on a mooring and would leave my dingy at a dingy
dock, they never bothered my oars or tried to steal my Sea Gull OB. Just my
dingy bailer..

I finally went to a recyling bin and gathered a dozen juice jugs, band sawed
them diagonally and left one in every dingy at the dock.. Never had any
problem with them 'borrowing' mine again.

However, next season I'm going to have to have a hand suction pump since I
found, last season, there was no way to get the rain water from under the
full floor board in my inflateable. I'll have to drill a couple ~1" holes in
the floor back near the transom for the suction hose.
