: I know none of you guys use them, but, just wondering what happens when a
: kayak tumbles to shore in the retracted position, or how it holds up if a
: person picks up a kayak by the bow to empty water out?

It is a great rudder. There are two retracted positions one with the blade straight aft (level with the sea surface) and one with the blade straight up.

But ofcourse if you are rude you can destroy everything. Personaly I dont think it is a rudder for the renting buisness
