I keep those guides for at least 5 years before I update them. Seems like the only major changes in the last 10 years is that the south barrier beach was breached by a storm at Katama Bay (in Martha's Vineyard) and that Brewer's has acquired more and more marinas from other owners. (Fortunately for cruisers guide readers they keep the old main phone numbers.) Oh, and they added the 631 area code in eastern Long Island, NY.
