Peinert's Sculling HOWTO

Dreher Carbon Sculls
|
To accompany any of our rigs we are pleased to offer
Dreher carbon sculls manufactured by the Durham Boat Company. We find these
to be the lightest, most durable, and technically advanced sculls on the market
today. The fit and finish is seamless and beyond compare. These sculls are
simply beautiful and an exceptional value.

The history: Durham Boat Company introduced boron enhanced
carbon oars (sweeps and sculls) in 1995. The high modulus sculls are overall
the lightest weight sculls offered on the market today and provide the best
overall swing weight characteristics. On the recovery, lower
swing weight results in far less energy usage and is especially
helpful in reducing fatigue as the stroke rating goes up.

The design: The Dreher Scull/Oar System was designed for
optimum performance. Dreher oars are light-weight, rigid, and built to last.
All shafts are autoclave cured at high temperature and pressure for maximum
strength and durability. Only the best construction materials are used to make
Dreher Oars and Sculls. All the major components are made from prepreg carbon
or, in the case of the blades, sandwich core construction of prepreg carbon and
specially formulated syntactic foam to obtain the highest quality parts with
the desired strength, weight, weight distribution, durability and surface
finish.
The design of the shaft/blade stem attachment point on
Dreher Sweeps and Sculls is worthy of mention. The transition point between the
blade stem and shaft is almost seamless. That is to say, the diameter of the
Dreher blade stem is not as large as on other brands, nor is the shaft to blade
stem transition as abrupt. As a result, the overall performance of Dreher oars
are superior, especially as the stroke rate goes higher. Less effort goes into releasing
the oar from the water, while less friction is observed on the drive as well.
The result is smoother entry and extraction, which can be felt and appreciated
by rowers who have tried other brands.
Some manufacturers use glass/foam composite for their blades
and glass composite handles instead of stiffer, stronger, and lighter
components made of carbon. Not only are the materials and design used in Dreher
Oars are of higher quality, but the components are also modular. If a Dreher
shaft is broken through a collision or an accident it can be easily replaced.
The blade can also be as readily removed as well as the handle. The blade is
held on with high temperature hot melt adhesive, so blades are easily removed
with an industrial grade heat gun or torch. If blades are broken or as new
blade shapes evolve, you might want to change your blades. With the Dreher
modular system, this can be done without the expense of purchasing a new set of
oars. The major advantage of the modular design is easy replacement of parts
and protection against product obsolescence due to blade shape optimization.
