The McKenzie dory or Rogue River dory also called by many a Drift Boat is an evolution of the open-water dory

Dory

The dory is a small, shallow-draft boat, about long. It is a lightweight and versatile boat with high sides, a flat bottom and sharp bows. They are easy to build because of their simple lines. For centuries, dories have been used as traditional fishing boats, both in coastal waters and in the...

, converted for use in rivers. The design is characterized by a wide, flat bottom, flared sides, a narrow, flat bow

Bow (ship)

The bow is a nautical term that refers to the forward part of the hull of a ship or boat, the point that is most forward when the vessel is underway. Both of the adjectives fore and forward mean towards the bow...

, and a pointed stern

Stern

The stern is the rear or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite of the bow, the foremost part of a ship. Originally, the term only referred to the aft port section...

. The sole identifying characteristic of the McKenzie dory is a continuous rocker. Rocker is a term used to define an arc from bow to stern along the bottom of the boat. It is this constant rocker that allows the boat to spin about its center for ease in maneuvering in rapids.

McKenzie dories are specialized to run rapid

Rapid

A rapid is a section of a river where the river bed has a relatively steep gradient causing an increase in water velocity and turbulence. A rapid is a hydrological feature between a run and a cascade. A rapid is characterised by the river becoming shallower and having some rocks exposed above the...

McKenzie River

The McKenzie River is a tributary of the Willamette River in western Oregon in the United States. It drains part of the Cascade Range east of Eugene and flows into the southernmost end of the Willamette Valley. It is named for Donald MacKenzie, a Scottish Canadian fur trader...

Oregon is a state in the Pacific Northwest region of the United States. It is located on the Pacific coast, with Washington to the north, California to the south, Nevada on the southeast and Idaho to the east. The Columbia and Snake rivers delineate much of Oregon's northern and eastern...

 in the mid-20th century. They have a wide flat bottom for low draft, a narrow bow that is flat, often mistaken for the transom

Transom (nautical)

In naval architecture, a transom is the surface that forms the stern of a vessel. Transoms may be flat or curved and they may be vertical, raked forward, also known as a retroussé or reverse transom, angling forward from the waterline to the deck, or raked aft, often simply called "raked", angling...

, which instead is pointed. The reason for this is that the rower faces downstream, therefore the part of the boat which first hits the waves (approaching from behind) must be pointed or very narrow to throw the water to the side. The bow is then widened so that a small outboard motor

Outboard motor

An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom and are the most common motorized method of propelling small watercraft...

 and/or anchor

Anchor

An anchor is a device, normally made of metal, that is used to connect a vessel to the bed of a body of water to prevent the vessel from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα .Anchors can either be temporary or permanent...

 bracket can be attached. Those unfamiliar with the craft would say that they are rowed backwards. McKenzie dories without a transom are called "double-enders".

McKenzie River dories are mainly used by recreational boaters who wish to operate a very responsive boat. Like the Rogue River boats described below, the McKenzie River dory provides a much more responsive boating experience than that of a rubber raft

Raft

A raft is any flat structure for support or transportation over water. It is the most basic of boat design, characterized by the absence of a hull...

. While the McKenzie River dory is a safe watercraft, operating any dory requires keeping river conditions in mind at all times.

Rogue River dory

Unlike the McKenzie boats, the Rogue River

Rogue River (Oregon)

The Rogue River in southwestern Oregon in the United States flows about in a generally westward direction from the Cascade Range to the Pacific Ocean. Known for its salmon runs, whitewater rafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act...

 dories are completely flat on the bottom with upward rakes under the prow and the stern. The Rogue River guides needed a boat with greater carrying capacity, and the ability to hold the current. The Rogue River dory is not quite as responsive as the McKenzie River dory but is typically larger than the McKenzie dory and is used where many people and large amounts of gear need to be carried. The high prow, great carrying capacity, and ease of rowing makes it the preferred dory

 for commercial use. The classic Rogue River dory with a nearly full deck is a favorite among guides on the Colorado River, while on the same river, the decked McKenzie River dory has a large following among do-it-yourself river runners.
