Captain and skipper both mean the person in charge of a boat. Captain is the general, formal word for officers on any ship. Skipper is informal, mostly for small boats like fishing boats. Not compared: captain as a team leader or military rank.

这两个词在“船长”这个意义上很接近，都指负责一艘船的人，但语域不同：captain 是正式、通用的说法，skipper 则显得随意、口语化，多用于小船。这里不比较 captain 的其他义项，例如“（队伍的）队长”或军队中的“上尉”。
