I note your comments about Colvin's preference for stayed masts... BUT (!)
I do think you have to look at the actual dimensions/angles of the stays
before passing judgement. On Fu-T'ien, the stays certainly prevent the sails
weathercocking, but allow them to get to about 10 degrees off perpendicular
to the c/line of the boat. I did have an unstayed foremast (before breaking
it in a 'controled' jibe to exit a goose-winged run) which had allowed the
sail to go over-centre, about 15 degrees before the mast, and it was
impossible to get it back with the weather sheet. I could, of course, have
dropped it altogether!
New Zealand Yachting Fed. inspectors recently looked at David Lewis'
problem, in which his ferro yacht sank after the broken mast foot pierced
the hull inside the boat. Their conclusion was a warning of the extreme
stresses at the partners of unstayed masts.
Incidentally... I am told by a fellow junkie that he was best able to
control his junk down-wing by sheeting in the foresail tight to prevent
rolling. I will try this when I have replaced our foremast.
It's great to be able to carry on these conversations...

I think it's unfortunate that Colvin has chosen the stayed rig. Although it
simplifies the design process, allowing the use of straight sided metal
pipe, it creates problems for handling and chafe.
However, there is no reason not to use unstayed masts for the Chinese rig to
gain it's full benefits. They were very common in the days of working sail.
We are surrounded by other successful examples, called trees. If the mast is
properly designed with appropriate dimensions and length of bury below
partners, it's quite strong.
I was a little apprehensive at first when I saw my mast flex in gusts but I
soon realised it was just absorbing the stresses and giving, not breaking.
To the untrained eye, the stayed rig may look salty, secure and traditional
but it's just another way of managing the same stresses. Unfortunately, you
now have the added complication of restricted movement and chafe.
I attended the summer rally of the Junk Rig Association in Southampton last

carbon fibber masts. Their specialty is the Aerorig, an unstayed Bermudan

I saw such a vessel on the Hamble river, she had an unstayed mast, 118

about twice as much as a wood spar. It just illustrates what can be done

My husband and I browsed your site. Your boat looks great! What kind of

I saw this junk-rigged vessel on a trip around Vancouver Island this
summer. I think of it as a "hobbit vessel" since it seems to me
that if a hobbit had a boat, this would be it.
Sailing off the wind produces excess weather helm unless I shorten the
mainsail early. She will stay junkrigged but would have a CE further
forward if the main were moved forward. Shrouds get in the way when letting
out sail on a downwind tack severely limiting the benefit of the JR. On a
number of occassions I have had the helm overpowered by strong gusts on a
downwind sail and been unable to let the pressure off by slackening the
sheets with the sail pressing up against the shroulds. This has had near
catastrophic results 2 or 3 times. She picks a heading under these
circumstances and steers like a train on rails.Only the God of the Sailor
has saved my ass. Bu'Kwiis is a mythical "wildman from the woods" in

Hi there... tacking on our 3-masted Fu-T'ien involves:
1. Releasing the workiing sheet (we have double sheets on the fore and
mizzen) on the foresail as the helm is put over
(gently);
2. If necessary, backing the mizzen sail to help her around.
There may be better ways! (Please advise). The main issue seems to be the
gentleness of the tack.
I haven't noticed any difference between the two tacks as a result of the
sails being on diifferent sides of their respective masts. FYI we have the
fore and mizzen on the stbd. side; the main on the port side. I think life
may be better if all are on the same side, so that all sails can be 'dealt
with' (raised, lowered, reefed) on the same tack. As a matter of preference,
I do not have the halyards going to the pilothouse (a la 'Pajama Jock'
McLeod), but leave them coiled at the shrouds.
I think a dipping lug is one thing, a balanced lug another. To have to
lower, then re-haul, a junk sail at every tack is looking for work. The
beauty of the sail is that it is self-tacking.

Jim, Where is this boat being built and how can I get in contact with Gene?
I am also building a Brent Swain and plan to rig it junk.

Gazelles are a design of Tom Colvin, naval architect and author of Steel
Boatbuilding and other books. He did the original Gazelle design for his
own use and wrote an article in a sailing magazine of the day, called Rudder
I think, which got a lot of attention to the design. It is a cutaway
forefront otherwise full keel design for building in steel. The junk rig
version is a schooner with stays but no spreaders on the main and foremasts,
and a long bowsprit with a jib. Mine also has a topsail. Most of the
Gazelles are built by their first owners - I bought mine from the first
owner/builder. If you want to see one, come up here to the Puget Sound - I
used to live within eyesight of Lick Observatory - on a clear day that is,
out towards the Los Gatos boundary of San Jose.

I'm excited to see this list and the relative wealth of experience
represented here. I have a Colvin Gazelle, which I've been sailing
about a year. We "circumnavigated" Vancouver Island this summer; the
boat did really well out on the rolly west coast of the Island; worm
gear steering is really cool! Indigo does not have a pram hood or
pilot house and we were freezing heading north in the Inside Passage
against prevailing northerlies. I will be following up on those
posts
with eagerness. I am also very interested in some discussions of
sailing technique/trimming/reefings strategies. With a junk schooner
plus jib and top sail, there are are a lot of variables to play with.
And, yes, as another poster noted, the stays are a bit of a hassle,
but the boat wouldn't look so cool without'em! With a couple of
boats
based on Vancouver Island, me down so. of Seattle (Vashon Island),
and
at least one or two other junks in the area who don't seem to have
discovered the list yet, we should have a junk rendevous.
Mid-October
in Pt. Townsend anyone???
so I am intrigued, why are you thinking of re-rigging?
in particular if you have been dissatisfied with the
junk rig, can you tell us all why, what problems you
encountered, etc? re-rigging is no small project so you
must be strongly motivated :-)
a stayless ketch would probably not have better upwind
performance than the junk... or so I would think from the
one ketch I actually sailed and another (loose footed)
that I visited. both owners confessed their boats were
real turkeys for tacking.
btw what does Bu'Kwiis mean?

I've heard that this rig is very simple,and read a lot of articles, but one thing confuses me. How do they tack ? The sail appears to protrude past the mast, so when you tack does the sail then need to go on the other side of the mast ? I guess this is obvious to practical users, but please explain in terms that a simpleton like me can understand.
Hi
My name is Steve Rankin. I sail a Gazelle with a pilot house. Bu'Kwiis can

schooner - a custom design for a friend of Tom's (a mini Gazelle,
actually). We're refitting also.
James - thanks for the picture of the pram hood. We have 2 companion

Hi there, I am the new moderator of junk_rig and am pleased to join
your group. I have a 42' Colvin 'Oothoon'called Fu-T'ien (3-masted
junk), based in Mana, New Zealand. It is currently being refitted,
whilst my family and I are living on Peace Haven, a 40' Colin Childs
2-masted junk schooner. I'll pass on your group to the owners,
currently teaching in China.
We look forward to swapping info with you.

Folks,
To see a 36' Brent Swain design under construction, see this site:
http://members3.clubphoto.com/gene232990/Boat_Pix_2/
It belongs to Gene Wunderlin who is going to rig it with a junk rig.
Fascinating building technique.
I saw a 46' one-off junk rigged version (named "Nothin Wong") in Halifax
recently. It was a two masted version with bow sprit. The foremast was
converted to gaff rig because the space between the foremast and mainmast
was too small. A donated gaff sail was mounted upside down so it would not
collide with the mansail.

Hi Leo, this project is not related to the Junk rig association. I thought
they would do well to have something like this, but got tired of waiting. I
was a past member, and have many of their back issues, but am not currently
a member. If you could mention the list to any members you are in contact
with, list the site on your website or mention it in the newsletter that
would be awesome!
On a furthur note, welcome to the list. We have 9 members, From Canada, US,
NZ and now Germany. It's only been going for a few days, so it looks
promising. Paul

I'm building an Bolger Advanced Sharpie 29 in Germany.
You can find my website at www.leow.de .
When not working on the boat this summer I most likely can be found
inspecting aluminum flagpoles standing all over the City of Duesseldorf...
Paul, is this your personal initiative or is it related to the Junk Rig

The pram hood slides around so it can face in any direction. It is held in
place by a retaining ring. My hoods are made from bronze plate and tubing;
the cloth from Sunbrella, I think. You can put a clear panel in the back if
you wish. They cost CDN$ 200 each to have made. They seem to work well.
See attached picture of BADGER's hood. That is Pete Hill. I can provide

Hi Paul,
Yes, we damn the stays every time the wind is at our backs! It's
especially difficult to sail wing and wing. Our masts are on
tabernacles, though, and I'm not sure that you could do that with
unstayed masts. We hope to cross the big pond to the east someday and
cruise the European rivers and canals so the tabernacles will be quite
handy.
We purchased our boat used. If I were designing a rig, as you are, I'm
not sure which way I'd go.
Jenny
Hi Jenny, your boat sounds great. How do you like the stayed rig? Do the
stays get in the way at all going downwind?
The pram hood is described pretty well in Hasler's book, it looks very
functional. If you don't have access to the book, maybe someone with a
scanner will send you the relevant info.
Anyone with pictures or links please feele free to add them to the site.

Hello Junkies!
I'm Jenny Meyer and my husband's name is Alvin. We sail a Colvin design
custon 38' aluminum boat with a jib-headed, schooner-type junk rig. Our
boat is identical to a Colvin Gazelle except a 6/7 scale (the Gazelle
being 42'). Her name is Tian Hou after a Chinese goddess of the sea.
We've been sailing the junk rig for just over a year now so we're still
quite new at it. Living in Green Bay, Wisconsin, our sailing season is
rather limited!
We're undergoing an extensive re-fit on our boat's interior so that
takes up most of our free time during the off season. What a job! If
anyone has any hints or suggestions that they think we should consider
incorporating, we'd love to hear them.
Jim- I looked at your site (We've looked at it before, actually) and I
see you have the pram hood on your hatch. How does this work exactly?
Does it simply rotate around the base and you turn it to block wind and
spray? What is it made from?- canvas and some kind of frame?
Paul- We're glad to see you've started this list. There really is a
lack of information on the internet and elsewhere. Thanks!

My name is Jim Creighton, newly joined member. I've been involved with junk
rigs for a long time now and I'm pleased to see that interest in this
wonderful rig is gradually spreading.
I have a website at http://www.nsjunkrig.org where you can see my boat and
other junk rigs in my neighbourhood. Check out the library section for an
interesting discussion on cambered sails.
Cheers, Jim Creighton
Hi, list members thanks for joining. I'm Paul, I will introduce
myself and invite yourselves to do the same.
I am finishing a 36' steel boat designed by Brent Swain on Vancouver
Island. I will be designing and building a twin masted junk rig for
the hull. I have been interested in the rig for a few years now, I
have read the books, and been a member of the junk rig association. I
have no practical experience with the rig. In searching the internet
I found some information, but not a place where I could get
information and answers to questions from experienced people, and
perhaps meet other like minded people. I look forward to hearing from
others on the list. I kind of hope this list runs itself, and
everyone who participates will benefit.
