Now that the Fort Washington Boat show is almost here, I'm looking into buying a boat. However, I have a few questions: What is the difference as far as advantages when buying a 4 stroke or a 2 stroke? Also, what size boat would be a good first boat? I would like to use it for the backbays, but also be able to run to a few area reefs (of course depending on the weather). Do you find many good deals at these expo's or are they just a place to go to do some research and look at the boats? I do plan on going through a boaters safety and navigational course, however, are they required? Any help would be appreciated.
