Carbo loading and rowing Very few rowing events are long enough to make carbo-loading beneficial.
Marathons are the only ones that immidiately comes to mind.
To carbo load, or store more glycogen than normal, requires a depletion phase of at least a couple of days where you eat almost no carbs, only fats and proteins. The idea is to completely use all your bodies reserves. Then, the day befor the event, eat huge amounts of carbs. Your body is starved for glycogen and will store much more than usual rather than just turning the excess into fat. Your body can normally store about 1 hour worth of glycogen without carbo-loading.
