We try to attend the "boat shows", and almost never go aboard the boats!!!
We shop the venders at the show for good prices. We have our list in pocket before we enter.
AND, we LOVE the seminars! Not sure about the East Coast, but the Pacific Sail Expo has some of the greatest FREE seminars put on by people who have personal experiences in the area!
One boat show is worth more than 5 years of any subscription to a big boating magazine (except Good Old Boat of course).
