When did Paul Jarman write Let go the long white sails and what is story behind it?

There seems to be a misunderstanding. There is no known work titled "Let go the long white sails" by Paul Jarman. It's possible there's a mistake in the title or author's name.

To help me clarify, could you please provide more information?

* Are you sure the title is correct? Perhaps there's a slight variation in the wording.

* Is Paul Jarman the correct author? Could it be another author with a similar name?

* Do you have any additional details about the work, such as the genre or a brief summary? This could help me identify the correct title.

Once I have more information, I'll be able to help you find the information you're looking for.
