Granted, this requires some domain-specific knowledge, but an order to 
"steer 245 degrees" means relative to north (and, technically, it's a 
heading, not a bearing, but that's another discussion).

If the captain wanted you to change you heading relative to your current 
heading, he would say something like, "turn left 10 degrees" (that may 
not be strictly the correct wording).
