Let's not forget either, it hasn't been set in stone that Salem is a Grimm. It could be that the sea dragon had designs on the ship after watching over boat traveling that sea route for months. They said they were never attacked by one that big, so that might mean it was lying in wait, watching as smaller weak Grimm attack and fell. Then it planned accordingly and swooped in on the same day Blake was there. If anything maybe it was egged on by Blake's depression.
