Smart Bottles are stout, puncture-resistant, double-walled plastic (BPA free) bottles that hold up to a gallon of liquid but can be rolled down to almost nothing when empty. They also feature grommets for hanging or securing in place, and integral handles and a screw cap spout for easy pouring.
We have both 1 gallon and 2-1/2 gallon Smart Bottles as well as spout that opens and closes and fits on either Smart Bottle.
We can think of all kinds of potential uses for them on small boats - from water storage to showering, drinkable water ballast, etc. The manufacturer tested their Smart Bottles in a drop test from various heights. The 1-gal survived a 15 ft drop. Small-boat adventurer Howard Rice saw their utility at once and carried six Smart Bottles on his recent voyage to Tierra del Fuego.
