The best vessel for this trip is a boat measuring between 30 and 36 feet. So if you’re sailing the boat at around 6-8 knots for 18 hours a day, it will take you around 14 days to reach Hawaii .
Generally, the best weather in Hawaii can be experienced in June, July and September. This is when travelers can expect the least amount of rainfall along with warm water temperatures. However, Hawaii has pretty great weather year-round (after all, the Aloha State experiences only two seasons).
