I also would equilibrate the dimensional ratio between the logomark and the wordmark, and the letter-spacing (in your last version is a bit stressed).
Discussion
What's that in English? Less letter spacing, and closer to the logomark? Also, played around with the colors, came up with a slightly different approach, what do you think? I think your version is probably the best still.
Far right is a nice gradient
Letter spacing: in the "Coracle" text the space between chars is too much.
The logomark (= the lines) is too big compared to the wordmark (= Coracle).
I'm usually not a fan of gradients but the last one is nice! However this way the lines merge a bit and the original coracle shape is less obvious.
This is a variation with the top circle in front of the big one but behind the bottom one, to give a more "intersection" feel:
