Of Swords and Parasols

I think a lot of the problem is that it's never really explained how much of Davy and his men was the original curse, and how much was Davy breaking the rules...we only really saw Davy and his men leaving for a few minutes if it wasn't to fight or hunt...it's possible they just couldn't stay gone for much longer, and we don't know how much a person could be on Davy Jones's ship without getting stuck there...it is just a poorly explained curse all around.
