Our Charter Insurance program requires that the vessel be operated by a licensed Captain. There cannot be any more than six (6) fare paying passengers and there cannot be more than 15 charters per year. The charter coverage we offer is not intended for commercial ventures. Other restrictions may apply.
NMU offers a program that allows us to pay commission to licensed brokers for referring business to us if they meet our requirements. We do not appoint brokers to represent us and we do not extend any authority to quote, bind, endorse, or issue on our behalf. If you would like to find out more about the referral program, please contact our customer service team at 800.262.8467.
Supply us with your policy number, the name and address of the marina, and we will issue the certificate.
You can fax, mail, or e-mail your new address. Include your policy number, your new address, and phone number. Be sure to let us know if the location of your vessel has changed and include the mooring zip code.
