If you're serious about boat shopping (walking through different boats), spend the extra $$ and go Thursday. Since it costs a little more, and since it's a weekday, you won't get as much crowds walking through the boats. You'll have plenty of time to look over boats in detail. Friday is better than Sat/Sun, but not as good as Thursday. Forget about serious boat shopping on Saturday. Boats will be packed with adults and kids running everywhere. If you're going to the show for meeting vendors in the tents, like we plan to this October, then weekends are fine. Another tip if you're boat shopping: don't buy too many painkillers at the drink stands!
