Все не так очевидно и увы чтобы об этом судить надо иметь какую-то практику обучения людей и подбора им снаряжения. Я сам раньше думал что мне 210 всегда хватает, но потом оказалось что на более длинной лодке 215 более удобно. Далее цитирую довольно нудный текст с любопытными выводами.Legalizer писал(а):длина лодки имеет мало отношения к длине весла. Вот высота посадки - да.
The euro paddle length data provided several correlations across both anthropometric measurements and boat dimensions. There were significant correlation between arm span and shoulder width and interestingly there was only a weak correlation with height. Boat length had a significant correlation while boat length multiplied by width had a strong correlation. Traditionally paddler height has been most commonly used when determining appropriate paddle length but this data suggests that arm span and shoulder width could be more appropriate anthropometric measurements. Arm length is strongly correlated to height but I would assume that if any height was a factor in paddle length it would be sitting height as I can’t see that leg length would affect paddle length choice. However there was no correlation found between sitting height and paddle choice. This would suggest that using height to determine paddle length is only taking advantage of the correlation with arm span and so using arm span would be more accurate. While arm span is related to shoulder width because shoulder width is part of the arm span I think the strong correlation with shoulder width could have some independence of its own. Shoulder width is often used to determine the appropriate distance apart to hold the hands on the paddle shaft. In my experience a distance approximately equal to or slightly greater than the paddlers shoulder width is most commonly used. This could explain the strong correlation.
The stronger relationship with euro paddle length was with boat dimensions. The significant boat length relationship was probably due to the fact that longer boats, because they’re faster, require a longer paddle length to maintain the same stroke rate. The strong relationship with boat length multiplied by width may be due to the fact that as well as this, a wider boat also requires a wider, or longer, paddle. This is supported by the weak correlation with boat width. The correlation with boat length and boat width lead to the strong correlation between boat length multiplied by width.
Surprisingly the Greenland paddle length data had no correlations with the anthropometric measurements. This was strange when you consider that the Inuit would specifically use anthropometric measurements when determining their paddle dimensions. Interestingly the Inuit would also use anthropometric measurements when determining their boat dimensions which would undoubtedly lead to a strong relationship between the paddle and boat dimensions which this study suggests is a more important relationship. However the Greenland paddlers in this study didn’t show that relationship either. It is possible that the Inuit methods of determining paddle dimensions don’t apply to western paddlers and their boats. Historically they are a stockier, shorter limbed people due to the evolutionary selection forces of living in a cold climate (Allen 1877) and as such applying their anthropometric measurements may be inappropriate for other people. It is also possibly that the lack of any correlations is due to the fact that greenland paddles are a relatively new introduction to modern sea kayaking and as such there isn’t a culture of education and information when determining the correct paddle dimensions. The small number of participants in the Greenland catergory (N=19) may also be a cause.
