Where are you coming from? You will need to check in with the Hawaii
department of agriculture web site is HDOA.Hawaii.gov if coming from USA mainland. Look for traveling from the US Mainland to Hawaii. Will you have any pets
on board? What island do you plan on sailing to first? If you are planning sailing to Oahu
(Honolulu) Ala Wai harbor is your best bet there are two yacht clubs and state docks. You can clear US Customs
and immigration there. I not sure about the US rules for foreign cruisers.
