Hawaii - Maui

It is possible to clear in at Ko'Olina Marina (Barber's Point) on Oahu. Officers came from Honolulu to board us and clear us in within 2 hours of arrival on both of our visits (April & June 2018).
We were required to pay for a local contractor to dispose of all garbage deemed "foreign" by the Agriculture clearance agent when arriving from overseas - the cost of this was VERY expensive: $150 + $90/bag, max bag weight 20lbs. We were advised that the only trash that could be guaranteed not to be deemed "foreign" and require expensive sterilization/incineration was clean beverage containers suitable for recycling that no animal or vegetable products had ever touched - i.e. soda and beer cans, water bottles, etc.
Even clean washed empty cans, glass jars (pickles, jam, etc) and clean plastic wrappers were required to be incinerated.

It is not possible to haulout in Ala Wai. Keehi Marine Center (Honolulu) on Oahu and Ko Olina (Barbers Point Harbour) offer haul outs, Keehi is cheaper.
If you need a slip, get one at the yacht Club, better facilities and security patrols constantly.

Mike Fossl reports that it is no longer possible to clear in at Nawiliwili / Port Allen.
