Row-Wing II Description
In 1994 we were commissioned by Alden Ocean Shells to design and build a
successor to their 'Oarmaster'. The charge was to create a product that
was differentiated from the 'Row Wing' and had the look and feel of the
Oarmaster line. The 'Row Wing II' is that rig.
The base of the Row Wing II is a ladder frame constructed by connecting
two flanged rails. These rails are formed of hard coat anodized 6061
aluminum extruded from our own custom die. Incorporated into the
structural shape are radiused longitudinal tracks. These tracks accept
our custom screw-machined delrin sheaves mounted on the same stainless
steel ball bearings found on all our rigs. The sliding seat is fitted
with six such wheels in our time tested design of four load bearing and
two captive wheels. The result is a smooth, quiet, and effortless ride.
We further construct a stretcher box and pan off of the stern of the
ladder frame. We punch, form, and weld .090 6061 aluminum sheet stock to
produce a simple, sturdy, and lightweight unit. This structure accepts,
without flinching, the power of your leg drive and the tourque imparted
by the attached rigger. The stretcher pan is fitted with non-skid
padding, comfortable velcro footstraps, and a built-in heel trap.
Optional plastic heelcups can be simply attched to prepunched holes.
The rigger is formed from 1.25" OD thin wall drawn seamless 6061
aluminum tubing. We form and weld (certified) this material into a
chevroned wing with the triangular geometry that imparts amazing
stiffness into a three pound assembly.
The oarlocks are molded of fiberglass reinforced nylon and incorporate
an adjustable locking gate. The locks swivel on our own screw-machined
stainless steel pins. These pins attach to the wing by means of a slotted
extrusion welded to join the main and supporting rigger tubes. This system
produces a rigid non-slip fixture fully adjustable for load (spread between
oarlocks), fore and aft pitch (for blade control), and height.
The Row Wing II is uniquely suited for mounting in Alden singles and
doubles. The 'Alden Mounting Kit' is necessary for attaching to the
stainless anchors embedded in their hulls. The ladder frame helps
distribute the load over a large footprint that will minimize the
'oil-canning' of a soft hull. The Row Wing II also functions well in
boats with a narrow cockpit such as a Klepper Kayak. The removable wing
rigger sits above the coaming and the ladder frame spreads the weight
across the ribs.
