In reality, even the fastest swimmers have technique limitations, but they offset them with strength and conditioning. The purpose of this series of articles is to address scientifically the technique misconceptions that have become \u201cconventional wisdom,\u201d and to present more effective options.<\/p>\n<p style=\"text-align: left;\">A longer hull length (i.e., body) is supposedly desirable because hull length is directly related to a theoretical &#8220;hull speed&#8221; or maximum practical speed for that hull length. The hull speed formula shows that a longer hull length has a higher hull speed. This month&#8217;s article explores the science related to the hull speed misconception.<\/p>\n<p style=\"text-align: left;\">More of this article on pages 14 and 15 of the August 2015 Issue of\u00a0<em>Swimming World Magazine<\/em>.
