Thanks, Graham for a very interesting posting. Choosing the right sail area, suited for the kind of sailing, the weather in the area, and not least to our physical limitations, is a central challenge.
Frankly, I wonder if Lin Pardey may have been a bit unfair to Arion. From looking at their Seraffyn and Taleisin, it appears that the ‘clouds of light-air canvas’ mainly consists of a big jib, set on a long, permanently set bowsprit. Their masts are not very tall, and the triangular mainsail with no roach at the leech (no battens) is not big. These boats appear to be ‘pulled by the nose’. This tactics offloads the rudder on a reach. I once spotted Taleisin in a regatta on a wooden boat festival in Risør, and noticed how they had spread the canvas horizontally, rather than vertically. Taleisin looked much like a gaff cutter, which had just had the gaff removed.
One big difference is that Lin and Larry were sailing Seraffyn together. Being two competent people on board makes everything a lot easier. Venturing out on the bowsprit to furl the jib (no rollers) is not for everyone, and to make it at least half-safe, a good helmsman is a must.
The biggest junksail I have seen in use is the 80sqm sloop JR of the 37’ Peregrine (see NL 48). Even if the owner and crews were young and fit, they ended up adding an electric capstan, but then they managed very well ( I think the sheet was divided in an upper and lower part as well). The manual winch was kept as a backup.
I think these electric capstans are brilliant. I have reckoned on it: The drain of the battery must be very low as hoisting lasts for just a couple of minutes (or less). They are quite reasonably priced as well. I bet that solar panels or wind generators will easily manage to keep the battery topped up.
With this ‘electric halyard’, and with the sheet divided in an upper and lower section, I think one can safely increase the sail area on a JR without adding another mast.
The remaining challenge is to have enough rudder authority to cope when reaching and running. A capable rudder is the key to let one rig with a broader and bigger sloop JR.

Yes, you are right, Arne, the Pardey's light weather sails were all headsails set from the end of their bowsprits, albeit very effective in revving up light air performance. No way I could get out to the end of that "widowmaker" at sea these days, and I even hated it as a young man, when I sailed from NZ to Tahiti on a gaff schooner. These days I don't like to leave the cockpit.
Peregrine's sail is impressive and looks a bit intimidating to me! 80 sq metres - wow! I've been thinking of an electric winch or perhaps a Winchrite for my halyard, which would solve that problem. The sheet is another matter. Separate upper and lower sheets can be good for controlling twist as well as sharing loads, I am told. It would be good if there was one person for each sheet. Being a solo sailor, I'd still have to overhaul them both at the same time. The ideal for me, as I get older and frailer, is to arrange the rig so it is effortless to sail at all times. I am not quite there yet, though I have taken to tacking in fresh winds instead of gybing, like Ketil does, which solves my problem in an inefficient way. (Once I have at least three panels reefed (20+ knots of wind), I find the sheet loads manageable.
I'd like a boat with uncluttered decks that I sail from an enclosed central station, just a Jester pramhood to peer out of, then I could gybe with slack sheets. If I sell Arion one of these days, I can think about it. There is a flush-decked fibreglass International Folkboat for sale in Sydney for next to nothing, very run down. It was set up as a daysailer with an open cockpit. I could put a Jester style cabin over the open cockpit and leave the decks clear. Not much room below compared to Arion but it would be a beautiful boat. We'll see what happens!
