I would advise trying to get a head start on the moster.  Do this by swimming straight toward the shore along a radial path to a distance 1/4 times the pond's radius.  Once there, swim along the circumference of an imaginary circle concentric with the pond until you are exactly opposite the monster.  You can achieve this since you have a higher "angular velocity" than the monster.  Once you are opposite her, swim for the nearest point on the shore.  You will get there first because you have to travel less than one-quarter of the distance which the monster has to travel.
