As Jim says. As close as possible to the deck as possible at the bow.

The “end plate effect” may not be the big gain that the aerodynamics theory may suggest. Possibly not a lot of air flowing across the deck if a Heron in non survival conditions. Maybe getting sail area up a bit and what is happening to the slot as the leach gets closer to the main As the job gets jogger could be more important-just a thought!

Sorry the autocorrect messed it up - it was meant to be the “jib gets higher” - not “the job gets jogger”! Makes a bit more sense

The genoa on my Javelin brushes the deck by at least 10mm.  Sounds good to me.  The Jav has jib racks so jib height and sheeting angle are independent.

My 3000 hasn't got a deck so it's a non issue, but I can put the whole jib higher or lower exactly so as to control the sheeting angle; in light winds it needs to be low to allow a bit more twist.

I've never sailed a heron but reckon your sail maker knows what he's doing!

However I still race her seriously & would to remain competitive.
From the tone of your replies I think there seems to be generally approval of the maximum median?
Thanks for your interest.




I would listen to Jim and not raise the tack. All sounds good and as others have said top marks to the Heron and the helm

I expect you've got a 79% genoa then as it's a newish boat. It'll still tack fine even with that amount of foot round which won't be of much use lying on the deck when close hauled but as you ease off onto a fetch it should still sweep the deck. You'll obviously need to experiment with tack height to get the right sheeting angle as you can't move the fairleads. A cheap and easy way to do that is to daisy-chain shackles together.
