Canadian Fairmile B motor launch

The Canadian Fairmile B motor launch is a type of boat. It was used in the military during World War II to help with things like patrolling the water and searching for enemy ships. It was made in Canada and was very popular because it was small and fast, so it could move quickly and quietly without being detected by the enemy. The boat had a lot of special features, like guns and radar equipment, that helped it do its job effectively. It was an important part of the war effort and helped keep people safe.
