i dont think so cause with the size of the boats they wouldnt be able to haul very many, all the boats have a diver flag on there mast and some other flag the diver goes into the water and it looks like he is fed through air lines and then a net of some kind is let out in to the water but it drifts into a big half moon quit aways behind the boat, swanny i dont think you will be able to see them from des moines peir cause they are in that little cove in between des moines and salt water st park, i see them from 240th and marine vw drive
