One of the things that made Hitchcock great was his willingness to experiment, rather than just sticking with a proven formula all of the time. While not all of his experimental movies measure up to his greatest achievements, they're always worth watching, and "Lifeboat" is much more than just watchable. It's a tense drama that combines psychology and action in an efficient and memorable style.
This is quite an interesting movie in several respects, and not least for the ways that Hitchcock squeezes so much out of one single setting. Into the simple "Lifeboat" setting, he puts lots of details that are both interesting and appropriate. The characters are interesting and believable, and most of all, the story is full of both suspense and substance. As an extra bonus, there is one of Hitchcock's most creative cameo appearances.
Aside from the technical features, it is also noteworthy to see the ways that the characters are portrayed, with the contrasts among them perhaps a bit stylized at times, but done so as to make some important points. The cast does a good job in making each of the characters come to life, and all of them get a chance to have some good moments. It all fits together to make an unusual movie that is well worth watching.
