I cringed a bit when I read your post. I don't want too sound to critical especially since you have the right attitude and realize you made mistakes. For the benefit of others it's worth mentioning a few things often repeated here.
On the subject of White Bay you should only overnight there with a perfect forecast. That happens less then 10% of the time. You should never overnight there without a updated forecast.
On sailing in areas that are red zoned there are always reasons that they were set up. The passage the poster took can be safely transited with the correct GPS waypoints. If you don't follow the exact right route then you are playing Russian roulette. There are several areas that will catch even a cat. The real question is why anyone would go that route when the recommended route is far more scenic and maybe 10 minutes longer. What is 10 minutes on charter verses a ruined week?
