The mentality here sometimes seems to be that unless you've already made many ocean crossings, you should never attempt one.
As I said in an earlier post, it's sometimes difficult to strike the right balance between skepticism and encouragement. But I'm sure you're aware that your statement above is a gross oversimplification. To the point of being actually untrue. In the whole history of human endeavors, the one thing held in common by people who succeed at difficult things is preparation.
The OP showed extremely obvious signs of not being prepared for this trip. What's wrong with pointing this out to him? He asked for suggestions and that's what he got. Honest, sensible suggestions.
