What are the energy costs of transporting a body from inland out onto the ocean? Probably less than cremation I suppose. Still, with some slight modifications I think you could improve efficiency. Load the bodies into shipping containers, to take advantage of all that existing logistics infrastructure, then push the whole container over the side once the container ship is an appropriate distance from shore. You can even tell families that Vinnie and Mathilda have become an artificial reef.
