The state Department of Land and Natural Resources says a skiff that floated into Oahu’s Kawela Bay may be tsunami debris.

KITV-TV reports the 20- to 25-foot skiff discovered Wednesday was covered with barnacles. A state crew found no invasive species but located a vessel identification number and turned it over to the National Oceanic and Atmospheric Administration.

The agency will contact the Japanese government to determine whether the owner wants the boat back.

More tsunami debris is expected.

A fisherman in September found a boat floating at sea. A 24-foot boat in December washed up on shore at Punaluu

The Land and Resources Department in July removed a boat found on Malaekahana Beach.
