Ask a broker?
Best way to find out is to call a broker and ask them. There was an article (in Cruising World ?) a while back about a state that was considering licensing yacht designer or making them pass a test to become certified, but don't think that applies to brokers yet. Calling around will also provide an opportunity to see if they need someone to help them out. Now is a good time to get going, because spring outfitting is getting into gear. It helps to be familiar with a variety of different boats and be knowledgable about their varying characteristics. (e.g. handling, construction, amenities and resale values) Different outfits focus on different areas as well. Some will be pushing one line of new boats, and that's all you need to know. Others will deal mainly with used boats, but will have one from every builder. I found it a VERY frustrating business to be in because the days you'd like to be out sailing (especially weekends) you have to be in tending the phones and showing boats. It's also a very economy-sensitive business, and it can be difficult to earn much of a living from it unless things are booming.
