The book does lead itself to a USA bias, hence the phrase American book for an American audience. And before the teddys get thrown out of cot its not a dig at Americans, far from it. Its a book for that very target audence group. Some of the techincal info can be transfered quite easily but there is a large element of the book is not relevant outside American waters. Homeland Security?
Is it misleading to call the book The ROV Manual, maybe a rename to The Observation Class ROV Manual would be more appropriate.
