It ended up that I didn't knit at all on the cruise. I finished the first clue the first week and then put it away. I picked up and started the second clue maybe in September. I got to the third clue in October. I finished the first wing in December. I started the second wing in January. It only took me 6 weeks to finish it.
My sporadic knitting habits do not make me a very productive knitter, but at least I finished it!
Thanks to A for modeling for me. Ravelry link here.
