Hello!

The gold insurance for children's education at sea (section C) not only stipulates that the insured must be 9 years old after 28 days of birth, but also stipulates that the insured in the main contract attached to the supplementary contract is between 20 and 55 years old and can participate in this insurance as the insured.

Therefore, the insured of the baby sailboat is between the ages of 20 and 55.
