oh I forgot 2 other very important items... Get yourself a safety pamphlet. You can download them from the marine patrol. Most of it is common knowledge like: have life jackets on board for everyone but it also will list important safety equipment required by the US coast guard and the Marine Patrol.
Also, make sure your sales man when you take possesion goes through this with you. Don't get so excited that you take her out and you get pulled over.
I have seen this happen a few time with new boat owners and all they get is a hefty fine on their first day.
If you have question the Marine Patrol is a great resource for this or you can visit
www.sbonh.org where there are links to safety info. Or frankly just ask right here and I am sure we can help you out!
Have fun, stay safe.
