An even further step in simplification is shown by the tablet Tahua, where we happen to be so lucky as to be able to compare with its writer's way of showing the double-canoe:

Tahua has a text which does not run parallel to the texts in the three earlier mentioned tablets, but some sequences of glyphs in Tahua do run parallel and here we have such an example.

You cannot make long seavoyages with only one hull. Where should the water and food be stored for the coming weeks? Therefore it must be enough to write only one hull, it will represent the whole double-canoe.
