I've been too lazy and drunk to find any of the old Galenjude games, but I am 95% sure he was the best at shipfights with the new rng ships, he is using ship S very well. I'll give it a try to quickly explain the specific use of ship S...
Alright, we got a navy battle, mhhkeeeey.. And the ships are like all at a line shooting at each other, all normal right. So what you do with your ship S is that you pull it forward a bit, and then pull back. The reaction of the enemy ships is to chase after the ship, forgetting everything else and waste valuable firepower. Now this is near useless in small fight, since the enemy is without doubt able to quickly regain control of the ships. But now, imagine this in a big fight, where both players keep pouring out ships from their ports and the lines are very thick, the taunted player got no chance to pull back the ships and are forced to watch his ships kill them self. So yes, if used correctly ship S is a bitch.
