This is a lovely little introduction to maritime archaeology and historic shipbuilding, but it's too short! Macauley himself noted that keeping it to 96 pages was hard enough, but I would have loved more descriptions of the technical side of a caravel--how it was sailed, how shipboard armaments were used, what kinds of provisions were brought aboard. Nonetheless, as with all of Macauley's books the illustrations are superb, the imaginary people and places involved were well realized, and some learned humor slips in.
I dug out Ship again after I found it on a shelf of childhood books and have to say that, though I received it as part of the RIF program in elementary school, it's a book suited to older readers. I think at the time, I enjoyed it more for the pictures than anything else. It certainly has much to offer for both kids and adults alike, and readers familiar with archaeology and maritime history will find much to enjoy, too.
