That product was released in 2014, before Iray was added in DS. The shader is likely a custom 3DL shader that Iray doesn't know how to "translate".

You could try selecting the object in the scene pane, then, in the Surfaces panel, apply a different shader.

If I encountered this item, I would start with one of the soapy water shaders in this product:  Iray Foam and Bubbles

 

The shaders might work to make that sea foam look plausible.  I've used them a fair amount to depict sea foam or turbulent water.  Keep in mind that shaders are not the same as Materials.   You apply shaders in the Surfaces panel.  Good luck!
