You've just taken a sea kayak class and are all pumped up about learning more? Hopefully the videos below will help you out. These are some of the best instructional videos I've come across on Youtube.

Off-season Boating, Cold Shock and Hypothermia Brochure and website describing the dangers of hypothermia and how to prevent it. If you are at all questioning learning more, here is a shocking quote from the website which will likely change your mind:
"On March 6th, 1968, nine elite marines, trained as water survival instructors at the Marine Corps Physical Fitness Academy, capsized while paddling a war canoe across the Potomac River. They wore sweat suits. They had seat cushions but no life jackets. The water temperature was 36 degrees F. None of these men were able to swim the 100 yards to shore. This is the bluntest of messages for all of us."
Cold Water Safety - for kayakers Atlantic Kayak Tours discusses the effects of cold water on a kayaker. The two main problems are drowning due to initial shock in cold water and the better known hypothermia. Some lesser known problems such as difficulty re-attaching a skirt due to numb fingers is also disccussed. A must read for kayakers! http://www.atlantickayaktours.com/Pages/ExpertCenter/Coldwater/Coldwater-1.shtml#

Paddle Float Rescue Nigel Foster discusses the story of a sea kayaker that had to leave his kayak at sea after failing a self-rescue with a paddle float in rough conditions. He goes on to discuss the practicalities of using a float, preparing it for use, and techniques that can be used in rough conditions. He also notes that competent paddlers in calm water took about 2 minutes to complete a paddle float rescue whereas a re-entry and roll took only 15 seconds! http://www.seakayakermag.com/1997/feb97/foster1.htm
