The main rowing scenes are at the beginning of the movie, though there are a few seconds of sculling at the end if you can endure the rest of the film inbetween.
The Opening scenes are of the Yale boathouse - a scull rowing past and the lead charater (Luke McNamara) erging on somthing that looks more like a medieval torture device than a concept 2. (mind you the film was secretly filmed in Canada... are there any rowing movies that aren't??)
In the second shot of rowing, our man turns up late to race the "ivy sprints" and leaps into the stroke seat of a Yale eight waiting on the dock and pushes off to race. Mid race, just as they're getting ahead, seven's swivels breaks (i ain't never seen a swivel break like that - see picture above) so he abandons ship, allowing the crew (somewhat inevitably) to win by a canvas.
There's a couple of seconds of a single rowing towards a castle about 15mins before the end when Mr McNamara sculls over to the society meeting to challenge his enemy to a dual and finally a bit at the very end when he rows across to a lighthouse in a coastal scull, then wanders off leaving it on the water..??? (perhaps the sea isn't tidal in New Haven)
Joshua Jackson rows quite well for an actor (if you ingore the dip at the catch and the washed out finishes) so the close up shots don't grate too much.
In summary: OK rowing, shame about the plot.
