German rigging 

The rigging of an eight so that riggers 4 and 5 are on the same side while the others alternate. 

Grip

The rubber or wood part of the oar handle you hold while sculling. 

Gunwale (or gunnel, saxboard)

Half Pressure

Hang

Pause at the catch before dropping the blades into the water. Also the suspension of one's body weight from the oar handles and the footstretchers.

Hatchets (a.k.a. big blades or choppers or cleavers)

Oar blades that have a bigger surface area than the `standard' (Macon) blades and have a hatchet or meat cleaver shape. The hatchets are a bit shorter (by about 7 cm) than the standard blades.

Head Race

Heats

The initial races to determine who advances to the finals.
