Keep in mind that the U.S. Coast Guard is not yet responding to DSC transmissions. Currently, monitoring is scheduled to begin in 2005. Cellular Telephones Having a cell phone on board allows you to keep in touch with land-based people and businesses easily. Cell phones, although very convenient on land, are less reliable on the water. Most are not water resistant, and their range is relatively short.
Cell phones can also be expensive to operate, although there are many different packages available.
Your communication power with a cell phone is limited on the water because the other ship you are trying to contact must also have a cell phone. Family Radio Service Radios Family Radio Service radios are intended for personal, non-commercial use like CB radios. They are very handy because they can be used on land for communication without a license. They are perfect for outdoor trips with friends and family where you need to stay in contact. And they also help with communications while still on the boat.
