The Phamysht appears in my multiplayer games to be a very good ship. It has a very fast-firing 'snipe' kind of shot that can cause problems to many ships from range. And if they manage to get close, they're going to take damage in the same way The Measured attacks up close except the Phamysht can also use its attack to gain health as well.
I couldn't tell if you could do this from the games but I suggest the ability for The Phamysht's opponents to be able to pick up their own crew back up if they manage to fly over them. The Phamysht already has the advantage because the crew floats towards its ship, so it would be nice if there was at least a chance to recover your crew.
