I saw many comments on technicality which might be true But I think, director wants to show those mistakes knowingly perhaps....Many people do risky steps just for thrill and our movie character might like that...It happens when we are overconfident on our infrastructure...My point is, mistake by an ammature solo sailer is a posibility...Anyway, I liked movie because of awsome photograpy and sound and for a suspense that what will happen next...One time watch
