My previous post should have been titled "Dancing Alerions".
I hope you will forgive this airplane pilot and son of an aeronautical engineer for thinking the name of the boat was "Aileron" rather than Alerion. Good grief Charlie Brown.
Alerion refers to a noble eagle. Aileron refers to the moveable surface on the outer portion of an airplane wing which is used to induce roll about the longitudinal axis. For me, the latter sprang to mind and that's what I wrote. Since sails work in the same way as wings, I think the mistake is understandable.
Sorry about that.
