I only have 9 clashes. I have five examples of "what he is". I must be missing something. I don't understand where the F comes from in the wordplay for 14 across. Perhaps I am wrong there. Any enlightenment would be much appreciated.
I've got a small Irish boat. The first three letters are the first three of a four-letter word meaning 'curved shape' (the last one is the dropped one) and the 'principally' leads you to the rest, a usual crossword device...
