I hadn’t noticed before that there’s just one card in the RWS deck for each suit / element featuring a boat or a ship. Hum.. it seems natural that Death would have one – allegory to Charon and the soul’s passage is obvious. Three of Wands I tend to see as a "Columbus card" with its three ships, and the ambivalent character of the King of Cups could be Signor Columbus himself (although usually associated with Dionysos, Poseidon or Fisher King of the Grail legend). What about the Sword and Pentacle cards? And did PCS paint these boats and ships just out of her sheer love for the Water element (+ the fact that she did spend a lot of her time travelling on ships) or did she have some greater plan behind it all?
