New to Sailing, please Help =)
There is an arguement for both but I prefer the MOB on the lee side. If they are on the windward side the boat being pushed away from the person. As the person approaches the boat from the windward side the person is likely to be pushed into the topsides by wave action. When the MOB is approaching from the leeward side the boat provides a lee and knocks down the waves, the rail is likely to be lower to the water but a large wave can lift and drop the boat on the person in the water.
