O.K. Arne, I understood what u don't get, man.

No, there is nothing common between the operation of a proa and that of a junk.

The Video below shows me single handed steering Why Not? anywhere I want, and holding course no rudder needed. 

https://youtu.be/AkwW9C7oS6w

A well made traditional proa will sail him self rudderless. They hold course like a train on rails as long as they are on a reach. Pacific Proas are believed to be the first multihulls in the world, invented around 10,000 years ago. They were made for a purpose, to sail the trades and to discover the world....

A windsurfer moves the CE. A proa sailor moves the CLR. Since you could always move forward and with your weight move the CLR forwards, you want the CE to be as far ahead as possible. So, once under sail, you can move further forwards then ME in the VIDEO. I cant stand by the mast! The mast is ahead of the boats CE, so by going there he heads up and slows to a full stop. I need to be half a meter back from the mast and he will sail close and fast, just because that's where my CE is. If I had a canting mast, I could probably move my CE half a Meter ahead of the mast, now I could stand a full meter forward, so the first advantage is that I'm getting more boat to use by moving the rig as far forwards as possible..........

Now lets assume that for example, the CE is half a meter ahead of the mast (mid ship), I can load gear further forward, I can move further forwards, but the most important thing is, that I can also run better. With the CE as far ahead as possible, if you load your stern with all heavy objects and crew, and your sail is as far forwards as possible, The great distance between CE and CLR will take you down wind as the boat is working exactly like a parachute. The sail is in front, and it's pulling the CLR that is far aft. As simple as that.

No rudders needed, watch the clip. Sorry, I didn't have time to find a flashy girl in a bikini with a sweet smile and over size body parts..... otherwise the clip proves the point pretty well, and proves that what white man is doing to proas is a crime. I have had very hard times on other forums, I've been fiercely attacked by Armchair sailors that have 328,049 posts in those forums, They just babble bull shit all day and do nothing else, When a new idea comes, they attack it in their funny way and prevent the "younger" members from putting in any input.........................

Bla BLa Bla........... 

Arne, It's been a bumpy road to get to where I am, internet trolls, the lot, I've seen it all.....

I'm not stopping, A proa needs it's rig far forwards to work!

The balance is achieved by moving CLR! not CE.

Rudders or steering oars, are needed only for down wind sailing! 

I will share the build here, with pleasure, and if you see anything wrong with the way I understood junk rigs please correct me.

Thanks and all d best

Arne, Good to hear from you man. 

It's not good, that's exactly what white man does and it's not good.

Proas want their CE far forward, as their CLR's are far ahead, That is due to three things, a rig that is placed on the bow, a bow with very little volume, and the wind that's pressing on the rig.

White man puts a fancy rig in the middle of the boat. The CE now is so far aft from the CLR (because, all proas "bow down to the wind" so CLR is normally around 25% to 35% of water line from the bow.). With these huge distances between the two, big rudders are used. Such a boat is caught in irons with no rudder at the back, huge turbulence is caused by correcting this mistake too. 

Such a proa will never balance and sail it self. forcing the sailor to constantly steer. Traditional proas sail rudderless till the wind is on a broad reach or she's running, otherwise they will balance perfectly from a beam reach to a close reach. Now that, is exactly most of the sailing multihulls do, because they are fast, The apparent wind moves way ahead, therefor most of my proa sailing has been close hauled.

The biggest problem with unbalanced proas is shunting. With my Crab Claw experiments I found that canting mast proas work much better then fixed mast ones, even though both are using the same Crab Claw. The canting mast rig puts the CE ahead of mid ship and the boat will sail rudderless. the fixed mast pats it just aft of mid ship and the boat will go only to windward rudderless. A sail hanging aft of a mast at mid ship, will put the CLR way aft, forcing you to add complication, weight, cost and labour to solve the problem. in other words, adding two barn door rudders. except for all that, these rudders must be operated all the time. The boat will just never balance.

So, on every shunt, the boat heads up, gets caught in irons, and you're stuck drifting down wind, you must raise one rudder, drop the other, wait till she bears away  finally you can head off again. This is what I want to attempt to solve, Shunting is crazy enough without dealing with 2 more rudders...........

A well designed Proa with a canting mast and a crab claw, bears away after the shunt, she gets on her way immediately. she will sail rudderless and will not loose speed while creating extra turbulence. 

Bottom line you MUST have sail area forward, so the Yard is a must.

May I add another conclusion I just came to....

The difference between armchair sailors, and sailors in an armchair, is that a sailor in an armchair, will end by asking: what have I missed this time?

Your input on the junk concept of the rig is important, as I have zero experience with them, I would really like to know what you think. I will just add that I don't want a tall rig, since proas have the least righting moment of all vessels (so I think), therefor I feel lower aspect is the way to go. 

All d best.

To the Association.

  All I know about junks is all I read on your site. In other words, thanks 2U I know what I know.

  I like the polite and gentleman way the association coexists and shares. It's crystal clear, that I need serious help. This is Make O'Break, for I feel the power of the force has been low in me, hence my failures with the "taming" of the Crab Claw rig.

  2 Years of rig design,always lead to, low stress and ease of reefing as the 2 most, equil and important characteristics a cruising rig must have.........

The Chinese Junk covers both perfectly, and I believe it belongs on proas just as much as it belongs on monohulls.

Your input is our wish. Please comment this Rig.

All d best
