Maximum Load on the Gunwhale?

[freeboatrsrce]

Hello, I would like to figure the amount a boat will heel (in degrees) when a given load is placed on the gunwhale. This is for a small boat, of 340 pounds displacement. From the cross curves of stability, calculations show the boat will have a GZ of 1.54 feet at 36 degrees of heel for a righting moment of about 523 ft-lb. At 36 degrees the gunwhale is at the waterline. Is it safe to say that you can place up to 340 pounds on the gunwhale without the shear line falling below the waterline?
