Relatively Light and simple to build and stackable they were used as fishing dinghies. There are many types of dory type boats in the world. VanGogh left us a drawing of dory like boats. Another example is the Portuguese fishing boats that have very similar lines. Various designs of dories show more or less rocker (curve) on the bottom depending on the use. Portuguese fishing boats show lots of rocker while some of the grand banks dory considerably less. Rocker allows a boat to pivot and be more manoevrable. Beaching dories and driftboats show a lot of rocker.
