The strategy for Hammerfest Level 10, Stuck Together, is to cut diagonally to remove a slab of ice from each side of the block. Cut as much as you can, but make sure it will slide into the water! Take another chunk off the right side, then use two cuts to try to drop everything into the boat. You can achieve both par and coin objectives in a single try on this level.

Tough level to get par; I posted a walkthrough at http://www.youtube.com/watch?v=qC9FXuS7zBQ
2 Cuts
Quickly make two diagonal cuts, from the bottom all the way up, making a triangle with the chest in it small enough to be crushed.
You have to do this many, many times to get the vikings to fall right. You need a lot of luck to make this in 2 cuts!
