Three miles of the Charles, start line to finish line, in three and a half minutes. A single. The river, the bridges, the arches and the buoys are where they really are. Your catch is the throttle, your pressure is the rudder. The cox has done this before: listen.
CatchSpace, up arrow, or both thumbs together. Meet the catch: early lifts the rate, late drops it, missing the water costs you the stroke.
SteerLeft and right arrows for pressure. On touch, the first thumb in is the pressure side; one thumb alone is hard pressure, half the boat.
BuoysOrange to port, green to starboard. Blades over is free. Hull over is 5 seconds, then 10 for each one after.
ArchesThe wrong arch is 60 seconds, like the regatta. An abutment stops the boat dead: 20 seconds and a wiggle to get off it.
Made for tablets and laptops. It plays on a phone, but the river gets narrow.
16 minutes of race in 3:30. Time is the score; the line is the story.
