[Help with trigger splash particle script when floating]

I have a request for some help with scripts. I am trying to make my own bow splash for sailboats and i am struggling to make the script being triggered when the object moves / floats at a certain speed and ends when going below that speed. Could someone help me with that? 

Kind Regards
