Jasper Winn has written a superb book about a sea kayak journey.Called Paddle - A long way around Ireland I honestly cannot recommend it highly enough.
Jasper is a professional writer, a great story teller, and has produced the best book about a sea kayak journey that I've read since Brian Wilson's Dances With Waves.
He also runs the excellent website TheSlowAdventure.com
It was after reading the book I invited Jasper to record a podcast which you'll find at Sea Kayak Podcasts.com and all the usual places.
