...Spunnaker

I was recently instructing on a sailing course, teaching the use of spinnakers.
I know I shouldn't make fun , but though no fault of their own really , the two students made every mistiake in the book.
Mostly this was due to some pretty appauling weather,a spot of poor communication, lack of decisiveness and a little bad luck.
They never managed to put the thing on upside down I might point out & they did manage

pull it all together at the end of the day & pass the course.

I guess there is no bad student, just a bad teacher . So I shall shut up now.
