JAE .21 GT turn fin question

[Greg Bonahoom]

Back when the JAE first came out, the team recommended sharpening both sides of the turn fin down to the start of the bend to help the boat track straight. I was looking at the latest instructions for the GT, and it specifically calls for sharpening only the outside edge of the fin. Anyone know why this has changed?

Greg, not sure where this all started. We have run fins sharpened both ways, very little if any difference. More importantly keep it thin and the taper as far back as you can.

Thanks Ron!
