"Would it be worth having a maritime lawyer proofread my contract?"
This is not really the Forum for these kinds of discussions.
These kinds of discussions should be held in Confidentiality between You, and your Lawyer(s), in a room panelled in Mahogany, and littered with Lawbooks. Pay the Big Bucks.
This is just possibly the most self-absorbed, and boring, post ever submitted here. And all for an old, and nearly worthless, Ericson... Which I assume, doesn't really wish to be further involved.
