Ha! You made that one tough...you didn't say whether you were in the boat facing the stern, or outside the boat facing the stern. Anyway, it's easy. If you're in the boat and you're facing forward (the direction of travel), the right side of the boat is the starboard side. Think of a car driving down the highway (in the US), the passenger is on the starboard side and the driver is on the port side.
If you are standing on the deck of the ship/boat and facing to the rear of the vessel (aft/stern) and you turn 90 degrees to your right then you will be facing port side (left). Now, if you are on the ground facing the aft/stern then you turned 90 degrees to your right you would be facing starboard (right) this is not true
if you're facing the stern of a boat and turn ninety degrees to your right, will you be facing the starboard side of the boat?
90 degrees to the right faces port, 90 degrees to the left faces starboard.
Depends on which way you're facing when you start. If you are facing the bow - which is the front of the boat - then you will end up facing starboard.
False, you'll be facing the Port side of the boat. The Starboard/Port convention is as viewed when facing the bow.
