: I was told by a friend that you could raise the bow of
: an overturned boat up out of the water and dump the front half mostly out
: if you have a rear bulkhead. That is assuming you have a pfd that has
: enough flotation. Have you ever tried this?

I'll wager that your friend has never tried this in the water. Sure, you can do it on dry land (by slowly rolling it to get most of the water out, then lifting), but if the boat is swamped, you're not going to lift it while in the water. Water weighs 8 pounds per gallon. Your PFD provides somewhere around 15 pounds of floatation. You do the math. It's hard enough to right an empty boat, let alone a partially flooded one. Be smart and either install two bulkheads or use float bags. It's not worth risking your life.
