To those of you interested enough to read this blog – I have a new website for rowers and coaches under development at CrossedBlades.com. I would be very grateful if you would join me in the development process by taking part in a very brief (2 minute) survey on our Facebook page at: http://bit.ly/1vCBO3A .
Thanks and best wishes,
Whether you are sculling or rowing, your blade is your second point of contact with the river (the first of course being the boat). The purpose of this post is to highlight an aspect of blade design which seems to escape many newer rowers and scullers. If you hold a blade horizontally over the water at about the height of your rigger and then lower it into the water you will notice that it floats. If you square it, it will float with the top edge of the spoon just above the surface and the loom above the water. This is not an accident. Blades are designed to float at the correct rowing depth – the depth at which they are most efficient, supporting the pressure of the stroke in the water while minimising the amount of resistance offered to the forward motion of the boat.
This is important because many rowers develop a habit of burying the spoon and a good part of the loom into the water at every stroke. This produces a heavy feeling in the drive phase of the stroke which they mistake for the weight of the boat. Allowing the blade to float at its natural depth during the stroke makes the same stroke much lighter – the difference being the resistance of the ‘bow-wave’ raised by the loom in the water due to the forward movement of the boat. The difference can be so marked that some rowers feel they are somehow “not working hard enough” when they first make the change to using the blade at the correct depth. The truth is that they are actually working much more efficiently and more of the effort they are applying is moving the boat because the ‘drag’ exerted by the blade is greatly reduced.
That said, getting a rower to learn how to ‘float’ the blade can be time-consuming if they have developed a habit of ‘pulling deep’. They have to re-learn taking the catch by letting the blade fall gently onto the water under its own weight and ‘locking’ the blade at the correct depth as they start their drive. As so often in rowing, this means they have to take a step back to make a bigger step forward. They need to break the catch into two parts, first feeling the buoyancy of the blade before beginning the drive from the legs. It only takes a little practice for most rowers to master this technique if they concentrate on it during drills – although it can take longer to break the habit of pulling deep during normal rowing.
One of the benefits for rowers of correcting blade depth is an easier extraction and tap down, resulting in better balance. Scullers may not see this benefit if they are pulling deep with both blades and it is very noticeable that many elite scullers bury far more of the blade than good technique would dictate. It may simply be that the force these scullers are capable applying makes the additional drag less significant, or that a deeper stroke is in less danger of an uncontrolled ‘rip through’ (where the blade loses its hydrodynamic stability in the water) at the pressures they are applying. Any elite sculling coaches out there care to comment?
Most clubs will have rules on ‘club colours’ for competitions so this is a short discussion of the clothing and kit a rower will need for training throughout the season.
Winter rowing. Any crew training reasonably hard will be generating enough heat from the exercise alone to keep them warm in air temperatures down to about zero degrees Centigrade. However, before and after the outing, crews will often be standing around in winter conditions and it is at these times that they need good clothing to keep them comfortable. Key items which every rower should have available to them include:
- A hat
- A water-resistant splash top
- A lightweight ‘technical top’
- An ‘all-in-one’ rowing Lycra
- Lycra leggings and / or
- Long socks
- Lightweight sports shoes
Personally I’ve never worn gloves in a boat but opinions differ on this. Coaches supervising junior crews should be aware that putting young people on the water in winter conditions without adequate clothing could be a prosecutable offence.
Summer rowing should ideally involve discarding all but the rowing Lycra and possibly a hat from this list. However you may also need:
- insect repellant
Winter or summer a rower should also carry a bottle of drinking water (or a sports drink) and a ‘rigger-jigger’ (a spanner 10mm at one end and 13mm at the other).
