Summarize the following:
One of the primary types of insurance you will need is general liability insurance. This will cover your legal expenses, court fees, and settlements in the event that you are sued by a customer who was injured on one of your cruises. This can help you avoid being financially ruined by one bad experience. You may also need insurance to cover potential losses of property in case of a fire or shipwreck. Contact major insurers to inquire about this type of coverage.  Customers can sue for any number of reasons, so it's best to get the highest insurance coverage amount that you can afford. Passengers can even sue over rough seas. You will need licenses to operate as a business and as a cruise line. The specific licenses will depend on where you are registered and also where you go stop along your routes. You will need to gain clearance from a part authority or local government anywhere you plan to stop. Because of the complex nature of these permits and dealing with local authorities, it may be wise to hire a consultant who can help you with this.   You will also need to obtain liquor licenses for the relevant regions if you are not cruising in international waters. In all case, contact the relevant authority (ports, the coast guard, local governments, etc.) to inquire about specific permit and license requirements. You must adhere to the CDC's twice-annual required health inspections, due to the outbreaks of various intestinal diseases on cruise ships. This is also a form of liability. Now that you're ready to sail, you'll have to attract customers to fill your first voyage. Set a date and begin creating a marketing plan to reach the right customers. Be sure to consider first exactly who you want to attract. Are you looking for elderly retirees or young people? Do you want families, couples, or single people onboard? Your answers to these questions depend on the nature of the cruise you are offering and will inform your advertising strategies and media choices.  For example, many cruise lines are now seeking to attract millennials by offering cruises focused more on adventure and destinations than on on gambling and shopping. Before you depart, run a check of all your ship's systems, crew members, and services. Make sure everything is running smoothly and efficiently. Your first voyage will need to go through without problems if you hope to keep running your cruise line for very long, so make sure to be absolutely ready before departing.

Summary:
Buy Insurance coverage. Obtain the required licenses and permits. Advertise your first cruise. Double check your ship, crew, and operations.
