OK, OK so I was bored! I found this info regarding the CG maximun weight capacity. Anybody care to decipher this?

Sec. 183.33 Maximum weight capacity: Inboard and inboard-outdrive

(a) The maximum weight capacity (W) marked on a boat that has one or
more inboard or inboard-outdrive units for propulsion must not exceed
the greater value of W obtained from either of the following formulas:

(b) For the purposes of paragraph (a) of this section:
(1) ``Maximum displacement'' is the weight of the volume of water
displaced by the boat at its maximum level immersion in calm water
without water coming aboard. For the purpose of this paragraph, a boat
is level when it is transversely level and when either of the two
following conditions are met:
(i) The forward point where the sheer intersects the vertical
centerline plane and the aft point where the sheer intersects the upper
boundary of the transom (stern) are equidistant above the water surface
or are equidistant below the water surface.
(ii) The most forward point of the boat is level with or above the
lowest point of water ingress.
(2) ``Boat weight'' is the combination of:
(i) Hull weight;
(ii) Deck and superstructure weight;
(iii) Weight of permanent appurtenances; and
(iv) Weight of full permanent fuel tanks.
(3) ``Machinery weight'' is the combined weight of installed engines
or motors, control equipment, drive units, and batteries.

I think you need the tiff that was deleted. The tiff is probably a picture of the formulas that you would use to find "w" which is the maximum weight. The rest is Coast Guard mumbo jumbo about how you tell a boat is level in the water.

I did not see any pictures while I was on the web site. Oh well. If the boat takes on water, there's too much weight in it!!
