The beauty of SOG's chit based system, allows for modified damage variables. Late night stealthy boarding actions spelled doom for many well armed vessels (provided boarding nets were not cut or put on). Say for instance, a well armed frigate with a burden of 5, her 200+ crew fast asleep may only draw 1 or 2 E chits for the first round or two (or randomly determined by d6), sort of a "drop your c#%ks, and grab your socks" situation. The customization potential of SAILS is awesome.
