Note second to last paragraph. We shouldn't experience any "tsunami" per se, but may have some "non-destructive" sea level changes, etc.
I think it depends on the harbor also. Keehi, where my boat is at, is an inland harbor. The inundation zone doesn't extend to even to the shore on my pier. During a full blown tsunami, I wouldn't leave my boat there. However, for the little waves we've had in the past few years, nobody here has had any damage.KrisB:haha... I'm still not sure I'd want to have a boat parked at a marina during that -- I recall hearing about the seas changing by a few feet in the October earthquake... there was some damage to vessels in Maalaea Harbour.
