That's where you sign up with the walk up dockside grouping offices. You will be joined up together with other people to split the boat equally. Typically there has to be a total of 6 fisherman signed up to make a group charter go. Group charters are a good way to go if there are only a few people and they do not want to charter the whole boat. There is no guarantee that you will get out fishing on a group charter.
Several things can keep a group charter from going out.
If there are not very many people in town, it is hard to get a group together, or if the weather is bad before the trip, people will not be walking the dock looking to sign up. If you are a little flexible you stand a much better chance. The biggest problem is that you cannot make a reservation for a group charter. It is strictly a wait and see situation with most groups being completed the afternoon or evening before the trip. During the busy summer months group charters are put together very quickly and it is usually not a problem.
