Generally speaking a coxswain should hug the shore when going against tide or stream, and should keep in mid-stream when going with it. (Mid-stream does not necessarily imply mid-river.) Over the Henley course, until 1886, a coxswain on the Berks side used to make for the shelter of the bank below Poplar Point, where the stream ran with less force. The alteration (for good) of the Henley course which was inaugurated in 1886 has put an end to this, and both racing crews now take a mid-stream course. The course is to all intents and purposes straight, and yet it will not do to keep the bows fixed on one point from start to finish. There is just a fraction of curve to the left in it, but so slight that one finger's touch of a line will deflect a boat to the full extent required. The church tower offers a landmark by which all pilots can steer, keeping it more or less to the right hand of the bows, and allowing for the increase of its parallax as the boat nears her goal. Over the Putney water the best course has changed considerably during the writer's personal recollections. Twenty years ago the point entering to Horse Reach, and opposite to Chiswick Church, could be taken close. The Conservancy dredged the bed of the river, and also filled up a bight on the Surrey shore. This transferred the channel and the strongest current to the Middlesex side. In 1866 a head wind (against flood tide) off Chiswick raised the higher surf near to the towpath, showing that the main stream flowed there. It now runs much nearer to the Eyot. Also the removal of the centre arch of old Putney Bridge drew the main flood tide more into mid-river than of old; and since then the new bridge has been built and the old one altogether removed, still further affecting the current in the same direction. There is a noticeable tendency in the present day, on the part of all pilots, whether in sculling matches or in eight-oar races, to take Craven Point too wide and to bear off into the bay opposite, on the Surrey shore. The course should be kept rather more mid-stream than of old, up to Craven steps, but the point should be taken reasonably close when rounding; there should not be, as has often been seen during the last six years, room for a couple more boats to race between the one on the Fulham side and the Craven bank.
