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:
