Seafairing Dwarves Race - Yes? No? Maybe?

Let that sink in - Maritime Dwarves. They make their homes on HUGE ships, both warcraft and generic island-sized boats. Generally, they are a Neutral alignment, but anger easily and fight to the death. They make their living from the sea. They are skilled fisherman, can dive to depths that would crush a normal humans lungs, and have invented many wondrous tools to help them dredge the sea bottom for sunken ships and minerals.

Good idea? Bad idea? Meh? Let me know!!!

Attached is my quick sketch of a Warfighter Seafairing Dwarf.
