M_Boats: Level Boat

I believe I read somewhere that the cockpit floor was tilted toward the bow and water would drain out thru the centerboard line hole. If this is true can one use the cockpit seats as a point to determine it the boat is level while on the trailer? Or are they also tilted to the bow? I want to get the mast set up with approximately 5'-6' of rake per Jerry's rigging instructions on the MSOG site. Of what use is the cockpit drain if above is true and you are not pooped?
