Mich. Admin. Code R. 281.516 - Weight capacity
Rule 6.
(1) The
capacity tag shall contain the weight capacity of the watercraft determined as
hereinafter provided.
(2) The
weight capacity of a watercraft for use with an outboard motor, except a
watercraft dependent solely upon the buoyancy of pontoons or similar flotation
devices, shall be determined by either of the following methods:
(a) The formula WC=7 1/2 LBD, where WC is the
weight capacity in pounds, L is the centerline length, B is the maximum beam
amidships, and D is the effective depth figured from keel to lowest
freeboard.
(b) Reference to the
manufacturer's capacity tag installed in a watercraft if manufactured or
offered for original sale in this state on or after January 1, 1968, or in
accordance with standards approved by the state waterways commission.
(3) The weight capacity of a
watercraft with a permanently installed engine, except watercraft dependent
solely upon the buoyancy of pontoons or similar flotation devices, shall be
determined in the same manner as for watercraft for use with outboard motors,
except that the weight of all machinery and associated operating gear including
battery, fuel, and fuel system shall be subtracted.
(4) The weight capacity of a watercraft
dependent solely upon the buoyancy of pontoons or similar flotation devices
shall be determined by applying the formula WC=[(62 1/2V)--Boat Wgt.] : 2,
where WC is the weight capacity of the watercraft, and V is the volume of both
pontoons. If equipped with a permanently installed engine, the weight of all
machinery and associated operating gear including battery, fuel, and fuel
system shall be subtracted from the weight capacity.
(5) The weight capacity of a rowboat and any
other watercraft for use without an outboard motor shall be determined in the
same manner as for a watercraft for use with an outboard motor, following the
formula expressed as WC=7 1/2 LBD.
(6) The weight capacity of a canoe shall be
determined by the formula WC=7 1/2 LBD x 2.
(7) The livery operator shall provide the
inspecting officer with information relative to the weight of the watercraft
either by reference to the manufacturer's rating or by actual weighing of the
watercraft.
