In his own words:

”Have you ever sailed from San Francisco to Hawaii? I have.
Have you ever rounded Cape Horn? I have, twice.
Have you ever transited the Panama Canal? I have.
Have you owned more than 20 boats in your lifetime? I have.
Have you ever sailed large boats competitively? I have.
Have you ever been hundreds of miles from land in a powerboat
under your command? I have.”

“My father and his chief mechanic once crossed the Atlantic in
winter in a 22' boat powered by twin outboards. Yes, it is possible,
