I just returned from Kauai
after being there for 2 weeks. My girlfriends uncle lives on the island & has a fishing boat
in a slip in Lihue. From what he said there are only 2 or 3 small marinas
on the island & they all have at least a 5 year waiting list to get into.
There is a awesome anchoring
spot in Hanalei Bay on Kauai during the summer months but in the winter there's no way you could be there. In the summer it's fairly calm but in the winter since it's on the north shore you'll see up to 15ft swells.
