For those who are interested in the technical aspects of rowing, here is a link to a dissertation (in English) from Vrije University in the Netherlands. The dissertation focuses on the impact of various mechanical and human physical variables on rowing. The Summary, starting on page 142 provides an overview of the results found. Thanks to Mark G. of Ottawa for sending this to me.
