This will only work if the canoe is made of a material lighter than water.

I guess it would be tricky with a boat that's sunk to the bottom.

'Less dense' than water, not 'lighter'.

But I imgagine if the density is identical to water it could also work, so long as you are able to grab it and pull it to the surface. I think she actually did this a little in the video at the beginning.
