I've tried both and they work well. Currently I have a standing lug
sail on my Piccup as I think it's more weatherly.
You can just go look at Michalak's articles to get the Piccup sails
measurements.

My scan is fuzzy, but I think it has about 45SF
of sail area.
The mast of a balanced lug rig is aft of the mast
for a gaff lug rig, so might be more suited for
retrofit on a Teal, IOW it might fit in the same
mast step.

This idea could probably be adapted to Teal
http://hallman.org/bolger/brick/gaff/
Be aware that the leeboard and the mast would need
to be relocated.
Jim M. has several articles on "Sail Area Math" that discuss this
exact question. Believe me, the math is not that hard - grade 6 level
at best.
Alternatively you could just look at some of Jim's plans. He uses a
lot of balanced lug rigs and posts the area on the plans. I know
there are several boats that use sails in that size range. IIRC
Pickup Pram.

So. Draw up a scale sized sail, cut it out, move it around until the COE
lines up on the xeroxed plan.
With the COE in about the right place you can vary the angle of the yard
and the placement of the halyard some to fine tune if there is excessive
weather helm.
It's an amusing way to spend an hour or two.
Jim Michalak put a lug on his Birdwatcher. Same idea -- perhaps he has a
essay describing how he did it on his web site.

Jeb,
That's exactly what I was thinking... I'm sorta hoping that someone has already "done the math" and figured out a drop in replacement lug rig for the 59 sqft spritboomed rig. I want to build a Teal next week, actually two of them, and would really like lug sails...
Hey, have fun sorting out that mizzen sail.... Looking forward to your pics and report.

Is there a lugsail version that would replace the 59 square foot sail
Bolger uses on Junebug, Teal, Surf, Cartopper etc.?
Thanks.
Rick
A couple of years ago I came across a net article about double dipping lug
experiments with a June Bug. Struck me as odd at the time but it appeared to
work ok. I had some success with a 72 sq. ft. Tyvek sprit sail with sprit
boom (like the rig used on melon seeds shown in latest Wooden Boat) on my
gypsy. Worked very well until the head grommet got blown out in a gust. I'm
convinced a miniature wind sprint lug (say 65-70 sq. ft.) would work on jb.

Hi Rick,
That is just what I did with my Teals. I rigged them as standing
luggers as follows:
foot 8', luff 7', leech 12' hollow no battens, head 7'8" laced on
8'x1.5" round yard, throat to clew 10'3".
The mast is 11'x1.75" round, no taper. I have no boom but it is easy
to just put one or a sprit boom if you want a better shape control.
The sail is slightly bigger at 65 sqft but a sail can always be
reduced in size, not expanded.
Hope I answer your question.
Cheers
