All crews good or bad or best spend most of their time concentrating on holding their hands at exactly the same height, because if 1/8 is holding his or her hands a few mm higher or lower than he or she did yesterday, then the boat won't be balanced, and the row will be miserable. It's all about trust. You can't compensate if they are doing so, by raising or lowering your own hands; you have to simply let them stop doing it. Everything sucks if the boat is not balanced and balance is all about hand height and no rower is going to jeopardize that by leaning to catch a tailwind. There is a practice called "rigger lean". If rigger lean is going to be practiced it is discussed and agreed upon and practiced as a boat. Rigger lean is about ergodynamics and has nothing to do with aerodynamics. https://www.google.com/webhp?sourcei...#q=rigger+lean https://groups.google.com/forum/#!searchin/rec.sport.rowing/rigger$20lean$20%7Csort:relevance I don't think that's the reason in the original picture though - I think that's due to the artist. It's a ****up. Their arms shouldn't be parallel. The oar handle describes an arc and is only perpendicular to the boat momentarily and the varying angles of arms is inevitable. For the same reason one shoulder of a sweep rower's body gets bigger than the other. |

It's a ****up. Their arms shouldn't be parallel. The oar handle describes an arc and is only perpendicular to the boat momentarily and the varying angles of arms is inevitable. For the same reason one shoulder of a sweep rower's body gets bigger than the other. It's far too long since I rowed (at St. Pauls, and never to a high standard, although I did make it into a junior eight) for me to use my own experience as a guide, although it probably has enabled me to understand what I'm watching as a spectator better than someone who never has rowed apart from maybe on a boating lake for leisure, in a wide, heavy boat with fixed thwarts! I'm going on the HUGE number of Cambridge boats I've watched training on the river Cam (most colleges have several crews, and there are also crews for Anglia Ruskin uni and others independent of the universities altogether, topped by the actual university crews - which usually have several current or future Olympians among them), and where the towpath is also a cycleway - so you have to watch out for the coaches cycling along with a megaphone in one hand and watching the crew they are training, rather than where they are going. The river is so crowded at favoured training times that they have to cooperate in time allocation to avoid traffic jams! The standard of the Cambridge university crews is world class - the University Boat Race is a national institution, and probably the highest standard of race rowed in a tideway in the world. Regarding balance - since four of the eight lean each way, balance is maintained. The tricky part is synchronising the transition from keeping bodies exactly in line to moving each body in the same arc as the sweep they are pulling! And I've heard enough crew briefings on dealing with head and tailwinds, where it is specifically mentioned. Of course, the entry level crews place less emphasis on it, and up to a certain level, balance certainly is everything, because nobody wins anything if the boat capsizes! It's only when you get to the point where that become automatic that you start looking for additional benefits and techniques, and that IS one I've heard and watched being trained. |
