Sticky Collisions

I just realized that whenever I catch a wave i am demonstrating physics.  When i am floating on the water, i am, for the most part, a stationary object.  My velocity is zero meters per second.  The wave approaching me is traveling at a certain velocity and if this is an example of a sticky collision, it has a mass too.  After I catch the wave, i have the same velocity as the wave, assuming i am riding the wave straight forward.  To find the final velocity of the wave and i the equation for a sticky collision is mass of the wave times the velocity of the wave plus the mass of me times my velocity equals my mass plus the waves mass, times the final velocity.  In a sticky collision, the my momentum before i caught the wave plus the momentum of the wave is conserved and equals the same momentum of me and the wave after the collision. I am sure a wave is not a good example since it probably does not slow down when it collides with me as it is related to the wind and tide and would have an ambiguous mass, but it reminded me of the concept of sticky collisions.
