The corners of the Cam

IMG_20191206_121911 As told to a visiting cox from Oxford. And for Fairbairns, which means you don't get to see the course beforehand.

Some resources:

* A map of the standard Head Course, from First and Third.

* A map of the Fairbairns course, from Jesus.

* A video of a Robinson VIII rowing the course.

The Cam is wigglier than the Isis. Most coxes, even good ones, will expect their crews to pull round, bowside or strokeside, on Grassy and Ditton and probably First Post (for the standard Head Course). So, expect this, tell your crew to expect it, don't get overenthusiastic and try to avoid it or leave it until too late. Also, don't just tell one side to pull harder, because they can't; or if they can, only at the risk of throwing out their rowing. So, you want one side to pull round, and the other side to back off somewhat. Ideally, to ease the strain of calls, arrange beforehand with your crew that if one side is told to pull round, the other side should just back off, of itself. Also, somewhat controversially, I'd suggest going into corners at 90% effort. Because Fairbairns is a long course (and there is usually no significant stream on the Cam), there is plenty of time to get tired, why not give yourself some margin on the difficult bits. This doesn't apply if you're elite, of course, but if you're elite, why are you reading this?

General: in the town section the river is narrower than you think due to moored boats. On the Reach, beware of shallows if you get too close to the meadow side; you're probably better off on the towpath side. Although there is little stream, you may as well gain what there is by staying in the middle, which has the advantage of avoiding the nasty banks.

The Corners

Elizabeth Way ("the Road Bridge on J's map): or, "the S bend". Not too bad, just watch out for the point when you want to change the rudder over.

Chesterton / Green Dragon: on the map, looks deceptively easy. But is quite sharp, see-also my pic above. You come into it from a relatively narrow stretch of water further constrained by moored narrow boats.

Ditton: most of a right angle. Going upstream, it is very easy to steer too wide, especially with a wind coming down the Reach. Downstream, make sure you don't take it too wide, you don't want to head into the Plough.

Grassy: is most of a right angle. It is easier to steer downstream; going upstream, judging the narrowboats on the apex(es) is difficult.

First Post: not too bad, a total of about 45 degrees, but quite sharp. If you end up going wide, watch out for the overhanging trees and bushes on the far side.

Just before you get to the "Motorway Bridge" (actually the A14 bridge) there is "the outflow" which comes in from the W (towpath) side and can slew the boat around in a somewhat unnerving fashion. Avoid this by being in the middle.
