Earlier quoted context omitted.
15' jump height on a killer whale. https://www.reference.com/science/high-can-killer-whale-jump... This Columbia 22 has a mast height over 30'. http://www.sailingtexas.com/scolumbia22103.html I don't sail, so I have nothing to prove, but something doesn't feel quite right about this story.
Sailing stories always become a little more dramatic with each retelling. An orca 15 feet above you on a small boat would be awesome and terrifying in a way units of measure cannot express.
And also never seen before nor since.
