If you really need more let it off so the sail touches to the back harness line position under load..
Now we need some wind so I can try it..
Yes, this is how it is done on Formula, slalom sails and free-race sails (like the overdrive from severne). There is an optimum downhaul setting that is always set the same independent on the wind strength. You then use the outhaul to adjust for desired power, while sailing, not the downhaul. On Formula sails, going deep downwind, the sail can even touch forward of the harness lines, while for slalom and free-race, touching the boom up to the leward harness lines are usually a very nice and powerful setting.
Looking at your pictures, I would say that you have the harness lines to far apart. Set them to about a hands width and you'll feel the rig much better. This will also help to get the right attitude of the sail, i.e. keeping the mast upright and letting the the foot of the sail touch the deck of the board. It is not so much about "closing the gap" as is it is about getting the right (as designed) attitude of the sail.

People will disagree with all the tuning being done with the outhaul.

Wave sails are different....

Thanks.
I know my harness line setting is old school and different to most people's and I know all the theory but it suits me.
I forgot to mention he said that the sail is really a 15kt plus sail ( which I knew). Unfortunately with my lightweight , and our crappy wind, I'm using it in lighter conditions than that.
its ok Sue ,this guy, Spotty held the record for a while check his lines .47,58 knots .

Try a bit less downhaul. Looking at the second last pic of the rigged sail it seems you're close to max downhaul. The crease in the second top panel is three quarters to the mast and the floppy leech looks like it's set for max twist. I'd back it off to halfway for max grunt. Adjust outhaul so the sail just touches the boom. I know on my sails it makes a big difference in grunt if I back off a bit of downhaul. Trade off is speed , but if using for light wind ......
It's worth a try.
ps, sexy looking sail.
pps, I never rig to numbers , they are often out. I always rig to that top crease .
Might give less downhaul a go . I know my light wind rigging isn't very good. I just set to specs and use the adjustable outhaul. I can't downhaul more out on the water
I think I'll stick to the turbo at this time of year when the wind is marginal.
Less DH makes the sail feel heavy (NP sails) while correct DH allows the sail to act as it was designed. I usually set DH the same everytime and adjust OH & clew hole. If it's really strong wind I'll DH a little more but too much kills the sail power too much. Sorry about the vague comments, LOL

Wave sails are different....
Severne wave sails aren't different. downhaul is set and forget too. Outhaul for tuning. Typically if they are under downhauled you get rotation issues. I'm fairly sure severne sails are designed to be tuned with the outhaul as it makes it easier to make trim adjust on the water or beach.
each brand has its own mojo so what works for one won't for another. Simmer for example reacts to downhaul more.
I find with my sails ,( NP, V8 and race sails ),if I'm overpowered, outhauling and flattening makes the sail twitchy. The centre of effort moves around. Im never comfortable in the harness lines.Extra downhaul works a treat. Its kinda the same in reverse for border line planing conditions. If I bag out too much outhaul to get enough power , I struggle to stay upwind. I'd rather a tighter leech and go slower with a heavier feeling sail and be planing and staying upwind . That's just heavy me.

So what is it exactly that you are trying to say here?
How does the tuning of a Simmer wave sail help with the tuning of a Severne free-race sail?
Ps,
If sails are not meant to be adjusted with downhaul, then why do some sails have max an minimum marks on the top of the sail ?

It depends on the brand as to how downhaul and outhaul react to each other.

It depends on the brand as to how downhaul and outhaul react to each other. I provided examples of 2 brands that react differently. Blanket statements like wave sails are different and slalom and formula sails are all rigged the same aren't helpful because it isn't the case. Probably why people struggle to rig sails
Severne have explained how to rig the sail and what happens with different downhaul. From my experience with their sails that's spot on. No surprise they know best. Of course it doesn't then apply that free ride sails from other brands are the same.
Just to add while I sip my coffee .
I've got a 3 batten wave sail. It doesn.t really go loose at the head. Still everytime I rig it up people say. Oh that needs more downhaul

Yep Daffy ( Sailquick) also has lines set like mine..
Hi Al, have you had a chance to use the 8.4 yet? Or get out and get a more informed feel for the other sizes? How does the big sail feel on an RDM?
I currently have 2021 Turbo 8.1 and 6.5 and was considering replacing them with Motos like 8.4 & 6.8 or 7.8 & 6.4. Not sure if it would provide much more than I have already but who doesn't love the thought of getting new gear Select to expand quoteNWF said..
Just received my SV Moto's last week in the UK!
Previously owned Reflex, Overdrive, Turbo and NCX
Yes, I read all the hype and was slightly concerned as I loved my Overdrives, and while the Turbo was light and punchy in the hands, It lacked the overpowered credentials I look for, so I was a little sceptical.
Anyway, so far I've used the 5.2 and 5.8 Moto in the latest storms on Futura 93 and Fox 105 and while I do not have any GPS speeds
I have to admit, I am very impressed so far sailing alongside other cambered sails at Portland Harbour Weymouth. The rig profile is clean, and sets like a race sail, but unbelievably light, stable and certainly fast for a twin cam. 
It is just plug and play and has very assessable performance for sure. I am now looking forward to getting out on my 6.8 and 8.4 in due course with ISonic 73.
Cheers
Al
