Flying the sail without the main to test its steering abilities

Photographer saying 'look at the camera'

Subject responding...

Need some tack line and looks funky flown like a spinnaker and not along the forestay but it was pretty much symmetrical

out and about

Getting busy in the pit

A very small spinnaker

 but a stable one.

Not 100% like an AP, very zigzaggy but with a feedback loop to the tiller does a decent job, despite the fin keel...
