getting from the water to the deck

this weekend i was sailing around the st. helena sound/port royal
sound area in south carolina, and while anchoring in the edisto
river, tangled some kind of line in my propeller. i put the anchor
down and went to cut the line away from the prop, when i realized i
could use the rudder as a way to get off and more to the point, back
onto the boat. everyone here probably already knows this, but it was
a revelation to me! seems like this might make the bcc a safer boat
in a mob situation. anyone have any thoughts or precautions for me on
the subject of using the rudder as a step back up onto the boat?
