Haw. Code R. § 19-42-52
Minor repairs to small craft and smaller commercial vessels may be made at the assigned berth and shall be completed within thirty days. If repairs are estimated to, or actually do, require that the vessel be out of service for more than thirty days, prior approval shall be sought from the department to initiate or complete the repairs in the harbor. Prior approval shall be sought from the department for any repairs requiring the use of cranes, lifts, and any similar devices within the harbor. Repair, reconstruction or major modification that would interfere with the free flow of other vessels, pedestrian, or vehicle traffic shall only be accomplished in an area designated by the department. Failure to seek approval as required by this section shall be grounds for the revocation of the use permit.
