I am currently trying to oder a copy of this book that shows or describes ships and boats in use in western Italian waters up to the 19th century. This would likely include ships and boats in use in the islands. I know from reviews, that some of them are present in the book. I will keep you posted about how to find a copy, though you may be successful just searching for it yourself.
