I believe Peter Lenihan ended up installing a second sprit boom on his
sprit-rigged Elver. Not sure if he put in some reef points.
One could perhaps just drop the upper sprit altogether and let the
peak of the sail fold down in a storm tri-sail shape in a bad blow.
Elver had the advantage of small jib and mizzen to help keep things
balanced.

When I go on a run I do what the old timers did, prop an oar between the clew of the sail and a thwart,using a boat cushion for chafing gear at the thwart. Doubles the downwind speed and is easily struck by un-nesting at the thwart.
Again refering to ancient practice, they are hard to reef, but an effective emergency reef is to knock out the sprit. and sail the boat to a place suitable for a proper reefing.

<snip>For example a sprit sail has no easy way to reef it. In the larger
sizes that sprit becomes quite a handful and it is a loose footed sail
which can bag out when going off the wind.
It's advantages are that the spars are short and can store well in a
small boat. Also it carries a fair amount of it's area up high in
clear air and the head or upper luff has no spar infront of it to
affect the air flow. That is - if the sprit is peaked up higher than
the mast.
Bolger explains that much better than I.

One of the reasons I bought my Epson 1650 was the friendly driver software that came with it. (and there's still several functions I don't use)
I can scan, format and post the issues for you, or you can scan them (at least 300 dpi) and send them to me and I'll take it from there. Tutoring at the remote is tough, even if you have the identical set-up. Too much of my operation is "Let's try this. Oops! Well then we'll try this" It used to send my wife screaming since she feared the computer gods would exact revenge, (but I knew where their power switch was.)
It is a great article and I'd like to see the additional material. Unfortunately, I don't have the color copy.
