For the first time in a boat race Oxford used Spade Blades.
The original naval oars used in Napoleonic War gigs were simply spars with no blade at all. So the first great development was to add a blade. But then the shapes developed:

There are theoretical considerations to do with the drag of the area of the blade away from the pivotal point whilst the blade is in the water. However to my mind the most significant change is to do with the catch, the initial start of the stroke in the water. The old narrow blades had to hit the water and keep it compressed otherwise the stroke tended to 'wash out'. Steve Fairbairn, in his poetic description of rowing style says

And he gathers aft to strike the craft
With a ringing bell note crack.

Well that 'ringing bell note crack' became much less essential. Spades held the water more significantly and decreased the importance of the sudden hit making a smoother action possible (and desirable). The modern hatchet blades are designed to smell water and latch on to it making 'washing out' less likely.

Oxford coach Jumbo Edwards tried to capitalise on a very strong crew by increasing the oar length to 13 feet - it may have been too much!
Cambridge trained utilizing an unwieldy and primitive device developed in Australia and called an "ergometer".


An Australian Ergometer (1960s)

Nobody can say rowing doesn't move with the times! It only took 90 years from the first patent (1871) to Cambridge trying out the idea. When was the first use in Oxford?
