Marinebasher is true to its name -- it resembles a predatory sort of aquatic creature (not a fish, whatever you tell me!), and it's armor class is just slightly above normal, due to both Kelvena's ehter based attacks, and the nature of her physical attacks, which require either ramming into her opponent, or swinging around to strike them with the tail of her gear. Both leave her vulnerable to attack until she recovers.
The gear was also designed to work closely with Grandgrowl upon merging, or so is the impression I got -- its place in the G-Element is, I think, central; more so than Grandgrowl, as she is the source of ether induction when the four merge. It makes sense, if they have to work together. But like all the gears, Marinebasher breaks into parts to enable the transformation.
This gear was granted to Kelvena when she became the Element of Water.
