Carlos Dinares likes to explain over and over to rowers the advantage of a long catch. For Carlos Dinares one of the biggest advantages is that by rowing long at the catch it is easier to have a well timed catch.
A well timed catch is a catch where the crew misses the smallest amount of water at the entry of the blade. In order to make this timing easier the rowers will want a be rigged in a way that the blade gets closer to be parallel to the boat. If this gets achieved with the help of the rigging, the angle of attack will be steep and it will be easier to put the blade into the water without having to accelerate it towards the stern.
Carlos Dinares believes that by using this principle rowers can develop a better timing at the catch on the water. Also Carlos Dinares uses the K factor on the rowperfect to facilitate the timing at the catch slowing things down and an easier development of the ideal power curve by rowing at low rates.
Carlos Dinares wants you to look at these 2 videos. On the first one you can see single scullers rowing at low rates. The low rate, load and long catch makes the timing easier in this video.
On the second video you can see a good crew that became Olympic champion in 1996 with scullers. This crew has a very good timing at the catch. This 8+ used the training on singles and sculling boats to improve the timing at the catch and later on be able to do it well on the 8+.
