Tom,
Yachts tend to leave furled jib up, you need to keep it fairly tight though, wind will pick it to ribbons, frost can also damage sails

The other downside of leaving the jib up all the time is UV damage. Some yacht sails have a dark band sewn to the leech and foot to protect.

Thanks for the update...

There is a "manual" available for the Argo online, that may help.
The Argo forestay is really only needed to keep the mast up without the jib.

I find the Argo excellent for teaching, but certainly raising/lowering the mainsail is always a pain...

Outhaul:-
This controls the amount of curve (draft, draught, belly) in the sail. Look up aerodynamics (NASA) for a long description. Basically, flat sail = little drive from the sail; more curve = more power. Start with a hand span of curve, as the wind increases, you can flatten the sail to reduce the power & heeling effect.
Gnav
No tension allows the boom to rise, this means that only part of the sail is at the optimum angle to the wind. More tension, and more of the sail is at optimum angle. 
Lots of tension will bend the mast, this makes the sail flatter and you have another way of depowering the rig...

That's a basic overview, try different settings and see what happens!

Is the OP trying to raise the mast and sails on the water or on the trolley?

If trying to do it on the water then I suggest doing it all on the trolley ashore, you can then get the boating pointing head to wind and you have space to avoid the swinging boom. Once rigged up walk the trolley into the water and pass the painter (rope from the bow to someone on the dock who can walk it out. Have a long line on the trolley back up the ramp and retrieve your trolley before joining the others on the dock.

A fair bit of gnav and outhaul tension while launching will reduce some of the swinging boom but once everyone is in and you are ready to move away it's wise to ease the gnav a bit until you have everything sorted and under control.

Agreed.
The Argo needs the mast and jib to be raised ashore.
We get the jib luff tension using 2 people.
The heavier person stands on the launching trolley handles, grabs the forestay (gloves really useful) and pulls the forestay outwards as hard as possible.
Person 2 hoists jib and pulls halyard into cleat (clamcleat).
Then the forestay is untied from the stemhead and tied to the mast support beam.
I usually put a piece of adhesive tape over the jib halyard just below the cleat. It reminds me not to uncleat the jib before replacing the forestay...
(Everyone's done it once!)
