Extract|| Hypothermia is not a danger until the winter months as the air/water temperatures drop. I consider a 100 degree rule, that if air temp + water temp is less than 100 degrees, I pay close attention to where and what I’m going to row, staying not only close to shore, but generally closer to home. One of the dangers of cold water is that if you are training hard, sweating and hot, and fall into cold water, it can cause you to pass out. Know your swimming limits. Do not row by yourself on a course or a harbour that would put you in a spot that you could not return to safely given equipment failure. All boats will float you even if swamped and filled with water, but miles from shore you are hard to see. A storm moving through can create two foot waves (very big for a shell) on an open bay. This is difficult to row or swim through. The shorter wider boats are best suited for really rough conditions.
