Junk rig on modern hulls

Thanks to Arne and the other Junk Rig Pioneers for publishing their research and experimentation.

I have beginner's questions: How much adjustment is necessary to the sail control lines when reefing or making large changes in sheeting, and how often?

Related to that, what has proved to be the best way to manage all the loose ends of rope? I was thinking of fitting spools downstream of the cleats to take up all the slack and keep things tidy; all of the control lines accessible from the main hatch. Adding in self steering, it's going to get messy...

Further, is there any way of gaining the ability to heave to? My thought was to have a double sheet system rather than single leach sheeting, and to have the attachment points to the hull on tracks adjustable fore & aft....giving the ability to haul the sail to windward for more maneuvering options.

Here, if I am lucky, this link should take you to a little write-up, called "Junk Rig for Beginners":

http://goo.gl/vzGLzi.

As you will see, I just use four running lines on my rigs (plus a new, experimental one, lately, called FUP, "fan-up preventer"). The four lines are
halyard, sheet, throat hauling parrel (=upper luff h.p.), and yard hauling parrel. The two last lines are used for trimming the set and position of the hoisted yard. They need no retrimming as the sheet is handled, but if the sail is reefed or unreefed, they must be readjusted afterwards, of course.

Heaving to is mentioned in that little write-up as well.

Hope this makes sense.

Thanks for the reply, and the info. Is the idea for the spools for taking up loose lines worth pursuing? And the double sheets? It's a little hard to try out here, 1000km from the sea in darkest Teutonia. Running thought experiments only goes so far, and the only patch of water here is a waist deep football pitch with DiY wind.

Best Regards,

Stefan
 
Stefan,
I have had 4 boats with sloop JRs, so far. I have seen halyards being coiled on spools and that worked well. On my boats I stuff the halyard in in the halyard bag (canvas) after hoisting the sail. This ensures trouble-free furling of the sail. When the sail has been lowered, the halyard bag is almost empty, so then I store the tails of the luff and yard parrels in them. I also have a bag where I stuff the sheet after the sail has been lowered. While sailing, the sheet stays on the cockpit floor, not mixed with the halyard, which, as said, is in its bag. I have not bothered with, nor felt the need for, separate port-starboard sheets on my own boats. I know of one who has separate upper-lower sheets on his big (70sqm) mainsail of his schooner, Samson. That works well (see photo of Samson, below).

Lovely boat, and a very interesting picture too! Is it ferro? It looks close-hauled in light winds and moving nicely.

The sails are on opposite sides of the mast...fore is starboard, main is port; yet the mainsail, apart from the lowest panel, doesn't look much affected by the mast. Has anyone in the west ever tried more pronounced offset masts? I've read the Chinese sometimes had some stepped practically at the rail.

Thanks again,

Stefan.
 
The other thing that must be fun to play with is mast rake.
 
Stefan,
yes, Samson is a ferro boat, based on the 45' Samson C-Deuce, stretched to 49' (Disp= 23ton). The sails are 70 + 37sqm with about 10% camber in the foresail and 8 in the main. This has proven to be both powerful and surprisingly close-winded. The foremast has quite some forward rake to move the foresail foreward. Still, generally I prefer vertical masts if I can. This generally makes handling, hoisting, reefing and furling easier than with raked masts.

Tad, thanks for setting me straight on how many different Chinese rig influences have been felt on the BC coast. Allen was one of many, of course. The result is a delightful presence of Chinese rigs on various hulls, some of them conservative, others bizarre.
It is awesome you have CHINA CLOUD's original hull lines on the back of a chart. That to me is an artifact of BC history.
In the SF area for many years was FREE CHINA, a 70' junk built in the 1870s and sailed to USA by some Chinese guys who decided not to stay in Mao's paradise. This was 1955. Here's some brief sailing footage.

When Harry Dring had it in the 1970s I got to crawl all over for several hours really taking a lot of notes on the construction. A marvelous little ship and so very different from what the norm is these days.

Hi. I would very much like to make contact with you, to discuss some junk rig posts - eg China Cloud and others. Off line. I am seeking material for the Junk Rig Association magazine. Is there a way to do this? Thanks

MM.......regarding modern sailing cruisers and their use.....I've written before that in light of the way these boats are used by the majority, their exclusive adoption of the high-aspect sloop rig is pointless.....they never sail to weather and only reach or run, and that only occasionally. On any given day (this week, the past month, and maybe next week) I can look out the window in perfect sailing weather and see 20 sailboats under power. The three under sail are reaching/running across the gulf, the rest are going north or south (ie either with the NW wind or against it).

T. Colvin has written (in Cruising as a Way of Life) that the jib on his junk schooners is considered by him a light weather sail and is the first to be taken down as the wind increases. As to heaving to he says that a junk has more reefing options that retain good balance than western rigs so it's not a major obstacle (in his view). Of course there are many modern fin keel boats which will not heave to in the traditional sense either.

In many ways the addition of a jib (or not) was apparently a style issue, with some practicality and balance gains added in. Godfrey (see above) was going on to me about how cheap his sails were (fabric purchase), thinking this would influence my rig choice. But he depends on his engine, I probably won't be doing that and thus will have a long bowsprit, some big jibs, and even a topsail eventually.

My wife grew up on this Colvin pinky.....

Do you have any pictures of that giant Pinky?
