Try this mods site. You have to register to DL some of the mods, but Carotio has a few different shore and seafloor mods, one is SH3 converted to SH4 and another is his own work I believe. Here is the link to the page the shore mods are on, you can look at SS's to see the look. They also change the shoreline.

Fairly sure this is one of them.
