Our ocean dory is a light version of the fishing dories built and used out of Pacific City on the Oregon coast. These boats traditionally were 20 to 24 feet long and ran with a 70 horsepower motor in a well. Ours are 17.5 to 19 feet and run with a 25 to 50 horsepower motor hung off the transom. Both of these flat bottom boats require less horsepower, plane at a lower speed and are more fuel efficient than their v-bottom counterpart.
