To travel by private boat from Dublin to France, Ireland requires each boat to have enough life jackets for everyone on board. A boat that carries more than 12 people must pass an annual inspection. Except for boats with very small motors, Irish boat owners must register their boats and obtain permits if they wish to travel on certain waterways.
In French water ways, the boat's skipper does not need an International Certificate of Competence to navigate on the French coast, but one is required for operating a boat on France's inland waterways. If the boat is French, the boat must have a French boating permit.
