Unless you're putting several large rocks or bowling balls into the baggage compartment, a C206 is not likely to be out of the CG envelope. It's more about the potential of being overweight than about being out of trim! And when you're flying pax in a small single engine airplane you really don't need an abacus to figure your cabin payload. What are you gonna do...ask a female passenger how much she weighs? She wouldn't tell you the truth.
