Honolulu local guide
Oahu boaters without room for a boat or camper at home have a handful of storage options. Honolulu's busiest launch and marina water is on the south shore, from Keehi Lagoon by the airport to Ala Wai and Hawaii Kai, while the Leeward Coast has Waianae Small Boat Harbor, a base for offshore fishing. The three options here span that: Ohana Self Storage near the airport, Extra Space in Kapolei on the west side, and the storage yard at Waianae Harbor.
Ohana rents indoor parking for vehicles up to 25 feet and outdoor parking for almost any size, a few minutes from the airport and Keehi Lagoon. Extra Space in Kapolei has 8x20 outdoor spaces and enclosed drive-up units that fit smaller boats. Waianae Harbor's fenced, camera-watched yard rents by the week or month at a posted $12.50 a foot of boat length, which makes it a handy spot for fishing tournaments on the Leeward side. Salt air is hard on trailers and engines, so rinse and flush after every trip.
Boating in Hawaii: most undocumented vessels are registered each year with the DLNR Division of Boating and Ocean Recreation, and anyone running a motorized vessel over 10 horsepower in state waters must complete an approved boating safety course and carry proof.
