The short work lives of ships like Casmalia show that sometimes the needs during wartime do not always fit in times of peace. The call for a large number of supply ships to move war materials to Europe never came about, as the war ended before they could be fully used. Also, it was not the goal to use these wooden supply ships for long careers in commercial business after the war. Rather, they were designed and built to meet an immediate military need.  However, because they were built using resources (wood) that did not affect other war efforts, their use could be seen as a success.
