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.
