I laughed when he got that little liferaft out and threw it in the water and it turned into a much bigger one. I missed the maersk flags. I groaned when he tacked and put the hole underwater. The lack of wind during storms made it hard to suspend disbelief, maybe redford doesn't look good with fans blowing 40 knot winds at him.
When he didn't bail the boat out the second time, I figured he was too exhausted. It was funny that he couldn't find his handle and had to make one, but realistically if he couldn't find the handle, the rubber in the pump bellows was probably rotted too. I think you'd get way more GPH out of the boat using the manual bilge pump than hauling 5 gallon buckets (by yourself)
When he lit his liferaft on fire, I think he did it intentionally. Basically saying "This is it, either they see this and rescue me, or I put myself out of my misery"
I heard they started filming the sequel. He really did get pulled from the water by none other than Arnold Schwarzenegger, Captain of the fishing boat that saw his liferaft burn. Arnold helps him track down the boats that didn't see him so he can have his revenge. As they are motoring at high speed at night they end up hitting the container, which is floating just beneath the surface. They look into a cabin full of water and holes where the prop shafts and rudders were sheared off on the container... and ALL IS LOST AGAIN.
