Ken Fink always used to drive home the fetch and duration factor in his 
symposium talks. He felt most reports by kayakers over estimated wave 
heights. Ken even went so far as to state that many articles he's read were 
not properly corroborated by the writer or editor. He said he was going to 
write a book about waves, wind and swell, specifically geared for sea 
kayakers. I'm still waiting.
