USCG certified capacities for the MRS

After a few back and forth e emails with the Coast Guard clarifying the formulas, we have the certified Maximum Capacity numbers for the Mississippi River Skiff.
They are as follows:

MWC  717 pounds
MPC    497 pounds (calculated with a 20 HP motor)  This is Person Capacity
 Number of Persons  4
 Maximum Horse Power  20

As we ran through the numbers we found the size and width of the skiff could handle up to a 35 hp motor.  But through our testing we felt it should be limited to a 20hp to keep the stern from squatting too much.
So if we limited the HP to 20 the formula allows for more person capacity.  This brought us up to 3.75 persons.  With the addition of 3.15 cubic feet of flotation, the skiff is certified for these numbers.  We will be adding floatation this week.
