"Sailed to Hawaii" is not a complete sentence; it is an incomplete sentence. It lacks a subject: we don't really know who sailed to Hawaii; the sentence would need to be for example "I sailed to Hawaii" or " you sailed to Hawaii" to be complete; but ideally some more information would also be added, for example "I sailed to Hawaii last month."
