Overall: Very nice job. I might note that the nominator might consider a shorter hook that would draw more readers. Like: ... that Herbert Grove Dorsey invented the first practical fathometer for ships? In this form the reader is lured into clicking fathometer to find out what the heck it is.Georgejdorner (talk) 19:19, 19 November 2015 (UTC)
@Georgejdorner: - thanks for suggestion = better improvement for a hook! Recently found a Flickr picture of a Submarine Signal Co fathometer model. --Doug Coldwell (talk) 19:35, 19 November 2015 (UTC)
