We would like to be able to allow all children to ride free or at a reduced fare. But, our Coast Guard license allows us to have a maximum of 16 passengers. The Coast Guard counts babies and children as full passengers. So, if we did offer free or reduced rates for all children, we would have to exclude older paying passengers. Economically, we can not afford to do this.
This is impossible to answer accurately, but I would say an average of 150 people (including tourists) in the summer and 40 in the winter.
