It's not a very convenient because it require the user to hold he's breath for a long period of time (since the whirlpool and bernacle stat take time make some effects and the stand is seemingly a close/mid-range Stand so the user can't just stay above the water). So yeah it might not be weak in water but still that guy wouldn't be even threatening if he hadn't an hostage and he's pretty much useless against any Stand that can make lasted the fight even more.
