    Hi there, where do I start if I have no experience, only being a crew on a sailboat, just nothing official.

    I need to get my USCG 50 Ton License

    Hello Kate! The Coast Guard requires a minimum of 360 days of boating experience since you were 16 years old. Additionally, you must have at least 90 of those days within the last three years to meet the “recency” requirement. This is going to be your first step – gaining or getting close to meeting the boating experience requirement. Then, you can start the next steps. Give our office a call at (609) 303-0664 to discuss further!
