As mentioned above, there are numerous reasons for needing the internet on a sailboat. Some are practical, some are for fun, some are for your sanity. Being isolated from society is bad enough, losing face to face interactions entirely can be very emotionally draining. Having access to the internet can help relieve that somewhat. Whether it is just giving you access to whats going on in the rest of the world, or something as personal as video calling with family/friends. Being able to watch movies, television shows, sports, and the news at will is a privilege that we all now have but often forget. Once we lose the internet, we lost that privilege.
