Advantages – extends the length of the stroke & fully engages the
power of the leg muscles

Disadvantages – momentum is lost as the rower moves forwards at the
end of each stroke, the boat pitches as the centre of gravity changes

Advantages – move 8 lbs of rigger and footrest vs 180 lbs of rower,
leaves more power for rowing, no check on momentum, no pitching
