(1) Where, on real property leased by it from a federally-recognized Indian tribe, a public port district has constructed and is operating a small boat moorage facility for the use of which it has established a rental fee schedule which is comparable to the fair market rental for comparable Pacific Coast moorages, the moorage rental fees paid by lessee users of the boat moorage are generally subject to the leasehold excise tax notwithstanding the exemption contained in RCW 82.29A.130(7), in all instances involving moorage leases for terms of 30 or more consecutive days.
(2) Notwithstanding the foregoing, however, the leasehold excise tax is not payable in the case of Indian tribally-owned vessels using the aforesaid moorage facility.
