With four, fifty-five gallon plastic drums how many pounds can I hold out of the water?

Would like to build a fishing boat, have plenty of scrap metal and four, fifty-five gallon plastic drums, how much will these drums hold?

Update:

Completely sealed drums, no leaks.

Update 2:

So I can hold 1,800 lbs of weight out of water?

    Well, you have 220 gallons of drums. A gallon is 128 fl oz (a cup is 8 fl oz, pint is 16 fl oz, quart is 32 fl oz), so you have 28,160 fl oz of volume. 1 fl oz of water is about 29.6 mL of water, so a volume of 833,536 mL. 1 mL = 1 centimeter cubed. The density of water is 1 g/cm^3, so your volume can hold 833,536 grams of water. There are 453.6 grams in a pound. That comes out to 1,838 pounds of water.
