These four categories cover the full range of scullers from the top elites to the entry-level recreational scullers as well as serious open water enthusiasts.

At the FISA Coaches Conference 2008 in Paris, France Dreher introduce the first aerodynamic scull named Aero. It was designed with a truly aerodynamic shaft, similar to an aircraft wing, and a hydrodynamic blade and was made out of higher quality carbon fiber with a manufacturing process never used for shafts before.

In order to offer a more economical oar to a greater variety of people we decided to manufacture a new scull, still aerodynamic, but with a conventional roll wrapped shaft. The shaft has the profile of a helicopter rotor blade. It is manufactured at essentially the same cost as our standard racing sculls. The newly designed blade E-H is slightly smaller in area with he widest point closer to the tip of the blade. We also offer the E-HX in high modulus carbon as well.

At the 2011 HOCR the Dreher E-H Sculls and EH-X were introduced and we started taking orders at the first of year (2012). For more information about E-H (Elliptical shaft/Hydrodynamic blade) versus the Aero Series: See the attached EH FAQ Sheet.

Following is the technical information for the previous three models:

All shafts are autoclave-cured at high temperature and pressure for maximum strength and durability. This process packs the carbon layers more tightly resulting in greater oar longevity. The completely modular system allows for custom tuning of length, handle size, blade type and blade pitch; providing you and your crews with versatility while maintaining cost efficiency and high performance standards. 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 produce 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 Oars 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 scullers who have tried other brands.

The Dreher Oar system was designed specifically for adjustable length. The key is the adjustable handle system consisting of an all carbon handle end that fits into the straight (non-tapered) end of the shaft. This makes for a tight fit that eliminates any movement between the shaft and handle, while at the same time provides a full 10 cm of adjustment or +/- 5cm from your desired average length. This "carbon on carbon" design eliminates the possibility of movement because the handle is precisely constructed to tightly fit into the straight part of the shaft. This method of manufacture was further enhanced in late 2002 to incorporate a manufacturing technique used for high modulus sculls. It has further improved the precision of the handle/shaft fit. All adjustable Dreher Oars are equipped with an extra long sleeve to accommodate the 10 cm of continuous adjustment. All adjustable oars have decals that show the total oar-length on the handle and outboard setting on the sleeve so as to easily derive the inboard setting without the need of a tape measure.

Blade Shape and Area Summary:
See below for a comparison of the blade areas of the seven of the eight sculling blades that we manufacture:

BLADE TYPE	BLADE AREA	BLADE TIP WIDTH	TOP LENGTH
DreherAero	800-850 CM*CM (Variable)	22 CM	43 CM
APEX-REX	743.5 CM*CM	11 CM	NA
APEX-R or APEX-RX	757 CM*CM	NA	NA
APEX or APEX-X	816 CM*CM	21.6 CM	43.3 CM
BB2198	796 CM*CM	21.6 CM	43.3 CM
