I said it in another thread - fixing some of the blatant errors would have made the film much better without taking anything away from the character and his story arc.
For example, how in the hell does the boat GET IMPALED ON A CONTAINER ON THE AFT STARBOARD BEAM while the boat is under sail? Then you've got the shaving, the laziness in keeping the water out of the boat, on and on. It just made no sense.
It's worth watching - but only on Netflix for free.
It is a rational response to a very stressful condition to perform a routine chore to give oneself a chance to think. During the trip when our transmission got stuck and we couldn't start the engine the delivery captain decided to break for lunch. It gave us all a chance to think and come up with a solution which we did.
2. Laziness in keeping water out.
I interpreted that as exhaustion not laziness. He had been working very hard for a long time and just had to sleep, he passed out.
3. Starboard beam impact.
It didn't look like the boat was traveling very fast. If he was crossing the stream for example and the container could be traveling at a knot or two in one direction while his boat could be going in a different direction and impact.
Yes it is highly unlikely that the collision point would be there just as it is highly unlikely that he would hit anything at all.
Hanks catamaran getting hit by a wave and forcing it backwards enough to damage two rudders instead of just breaking a set screw is probably even more unlikely.
I think that was the whole point of the movie.
Unlikely things happened to a tough capable guy with a lot of experience to the point where his life was at risk.
Every time I've been in a situation that was dicey it could easily be argued that in every case everything that happened was very unlikely.
It is just in my case, so far, the sequence of unlikely events didn't exceed my ability to handle them, YET.
The point of the movie IMHO is that even capable level headed experienced guys are subject to the forces of chance. We don't always make it.
