Here are thirty roll-causing factors and how to avoid them.
1. Under-squared or over-squared Blade.
2. Getting caught in the water at the finish.
3. Washing out at the finish (rowing into the lap).
4. Pressing the blade down on the water during recovery – try to recover off the water.
5. Cocking the wrist up at the catch.
6. Not catching, recovering, or swinging together – watch the outside shoulder of the rower in front of you.
7. Lifting knees too early.
8. Rushing the slide.
9. Not rolling up together (wind catches blades unevenly).
10. Hesitating at the catch.
11. Stroke setting is an uneven tempo, rhythm, ratio or stroke length.
C. Hand Heights
12. Hands too low or too high during recovery – if down to port, ports should raise their hands (i.e. the oar handle) and starboards lower theirs slightly (or vice versa).
13. Hands not at an even horizontal plane during recovery or drive. Remember to cooperate with the other rowers in raising and lowering your hand height slightly to compensate for set problems.
14. Not lifting hands into the catch.
15. Random/excessive adjustment of hand heights by individual rowers – in theory you should find the proper handle height and keep
it there, but in practice due to set problems and/or waves, some adjustment is necessary.
D. Posture/Body Angle
16. Lunging at the catch – set your forward body angle by half slide, don’t change it in the front half of the slide.
17. Not keeping head in boat and body over keel.
18. Leaning away from oar.
19. Excessive layback – sit up straight, lay back into bow 10 degrees, swing 15 degrees forward body angle.
20. Dropping outside shoulder (usually accompanied by leaning).
21. Not putting outside arm between legs.
22. Pressing feet against the foot stretcher unequally during the drive, or pulling up with toes during recovery.
23. Not keeping the collar against the oarlock.
24. Rigger set too low or too high.
25. Oarlock pitch wrong (should be about 5 degrees), or foot stretchers set unevenly, or oar collars set irregularly.
26. Weather conditions.
28. Equipment problems (stuck rudder, weeds around rudder, bent skeg, bent rigger, stuck seat, etc).
29. Talking in the boat.
30. Uneven distribution of rowers based on size, weight, strength, length
