What Is the Difference Between a Dory and a Skiff?

The hull shape. A dory has a narrow flat bottom with high, flared sides that widen toward the top. A skiff has a wide flat bottom with low, nearly vertical sides. They look similar at a glance, but they handle very differently on the water.

The Hull

Pick up a dory and look at it from the bow. The bottom is narrow, maybe three feet across. The sides flare outward at a steep angle, spreading to five feet or more at the gunwales. That V-like cross section is the defining feature. It means the boat sits low and narrow when empty, but as you add weight, more hull enters the water and the boat gets progressively more stable. Loaded with fish or gear, a dory is remarkably steady.

A skiff is the opposite approach. Wide, flat bottom. Low sides that go more or less straight up. It is stable the moment you step in, even when empty. That makes it a great platform for calm-water fishing, crabbing, or messing around in a harbor. But in rough water, those low sides and flat bottom work against you.

Where They Came From

Dories were designed for the Grand Banks cod fishery. They needed to stack on the deck of a schooner, launch into open Atlantic swells, carry heavy loads of fish, and survive conditions that would kill you if your boat failed. Every feature of the dory serves that purpose: the narrow bottom for stacking, the flared sides for stability under load, the high freeboard for rough seas.

Skiffs evolved for protected waters. Rivers, bays, harbors, shallow flats. They are easier to step in and out of, more stable at rest, and simpler to build. They do not need to survive the North Atlantic because they were never meant to.

Which Should You Build?

If you want a boat with real heritage, serious seaworthiness, and the ability to handle open water, build a dory. If you just need something flat and stable for pond fishing, a skiff is simpler. Both are good first builds. A dory is a more capable boat, and the build is not significantly harder.
