I think the boat will move towards left w.r.t to water....for no displacement of center of mass. if not so then explain the answer.

yes this is correct. The boat will be to the left at the end of the whole thing.
But does it mean that it will always keep moving left? and also what will be the velocity during this period? (not that this is extraordinarily tough!)

it wont go on moving... the movement of boat will just be to compensate movement of centre of mass. velocity we cant say.... for that we need time or velocity of the persons and boat length..
