Haw. Rev. Stat. § 462A-15: Pilot association.

The pilots licensed under this chapter, each of whom shall be deemed an individual contractor, may form a nonprofit association which shall not be deemed a partnership or corporation for liability purposes, in order to provide such arrangements and facilities as may be necessary and desirable for the efficient dispatching of vessels and rendering of pilotage services required under this chapter. The association shall have no control over the selection of persons to be licensed as pilots or their discharge. The association shall have no direction over the manner in which an individual pilot performs the pilot's duties. The association may adopt any working rules that are not inconsistent with the law or of the rules of the department.
