fishing boats, and so did certain Greek cargo vessels, plus a few
experiments in the UK yachting world.

I think this would be more complicated than necessary. Because the
balanced lug sail sticks out ahead of the mast, including both spars,
a jib + stay would get tangled up with the lug sail during a tack.
Doesn't seem to be the brightest solution. It would make things
easier if the luff of the lug was brought back to the mast. But then
you'd have to recalculate the balance of the sail plan.

balanced lug sail sticks out ahead of the mast, including both spars,
a jib + stay would get tangled up with the lug sail during a tack.
Doesn't seem to be the brightest solution. It would make things
easier if the luff of the lug was brought back to the mast. But then
you'd have to recalculate the balance of the sail plan.

Has anyone in the group had experience with, or seen, a balanced lugsail with a jib?
Boat Design Quarterly No10 has a small cartoon of Bolger's "Sainte Valery" with a jib set forward on a long running bowsprit. I would be interested to know if the jib provides much assistance.

Balanced lugs seem to suffer from a little of the problem of their cousins,the Chinese lugs,in that they seem to set a little flat and can stall if pinched too hard. A small jib certainly acts as a leading edge flap and 'turn' the airflow around the leading edge of the sail to reduce unstable eddies caused by a too coarse angle of attack. This is only from personal observation and not backed up by science so it may be wrong. Go experiment on a small skiff and try it out. Andy

I have no such experience. But in the text of that same BDQ
article about St. Valery Bolger is quoted thus; "It would be
possible, and much in keeping with the style (of French luggers)
to set a jib on a long running bowsprit, and a topsail over the
mainsail. Perhaps, still in keeping with the style, a topgallant
over the topsail? In fact, the added sails and spars would take
up valuable space, to say nothing of cost, and are not reasonably
appropriate in a boat that ghosts with her motor."
In other words, don't do it. Bolger's cartoons sometimes show
what is not desired rather than the opposite. His drawings of the
happy (?) crew crouched in the cuddy of a "trailerable seaworthy
cruiser" come to mind.

Vance

lug with the boom so far back it's nearly a standing-lug sail, or it
*is* a standing-lug... I've never seen an actual boat with such a
setup or sailed one.
