Location: Oriental, NC In the T top, which one do you want to grab hold of to keep from going overboard? Location: Jacksonville, Florida All the comments about stainless are true but I can't remeber when I last saw it used on a boat like the one in the OPs original message or any other. Location: Florida All above is true, but if you price the labor and materials you might find Aluminum a lot cheaper and as good if you have it anodized.

Simply compare to existing similar stainless parts such as the stanchions mentioned, or bow and stern pulpits. I've seen anodized aluminum with a few years on it (spars) and refreshing the surface back to original is impossible or at least prohibitively expensive. Location: Adriatic sea If you use aluminum with stainless fasteners you might as well put it together with rivets because after a few months at sea you cannot take it apart anymore. As Alan White says in post #4, the price of stainless tubing is only a small part of the total costs. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
John is an prolific small-boat designer and builder from Texas, who’s built fifteen boats in recent years, including designs in wood, composites and skin-on-frame.
I noted that you are a fisherman and built your kayak for a more stable platform than conventional kayaks.
I note that your 12 footer can carry two men and a load of fishing gear so I think it should be able to cope with me and my dive gear (about 230 lbs). I hope you don’t mind me asking all this and if you can give me any tips on construction, it would be greatly appreciated. The hulls were parallel to each other, but they were asymmetrical when viewed from the ends of the boat. With two passengers plus gear on board, these aluminum tubes you’re using to attach the 3 pieces together might bend. Learn more about the W500 - the world's stablest fishing kayak that enables true stand up kayak fishing to regular people who fish in real-world conditions. These kayaks have much more storage space than any other kayak, and they are absolutely back pain free. Kayak Stability and Fishing StandingA kayak's stability is key, especially if you want to fish standing in it in full confidence. Many kayak manufacturers claim they designed their kayaks for stand up fishing, but other than pictures in glossy magazines and videos showing young and athletic fishermen who stand on their kayaks and fish in mirror flat water, how practical are these products for average anglers in everyday fishing trips? Can a middle aged or elderly fisherman feel at ease getting up and standing on a SOT kayak, and could they ever feel confident fishing from it? There is more to standing up and fishing from a kayak than just that - You need to do it comfortably and safely, have a plan B in case you lose balance, and be able to focus on what you're doing i.e. Location: India Asian style 20-25 footer Do you mean 20-25 ft coastal wooden fishing boat ? Wellydeckhand Previous Member   I dont get it Ari say Asian boat is sampan but I get chinese junk boat as sampan.

Location: Phoenix Michael Kasten seems to have a fondness for the junk rig.
Simplicity: With a schooner or ketch configuration arranged in true Chinese junk fashion, therefore not having a western jib, there would be just two junk sails, therefore just two halyards total. Ease of use: On any cruising vessel, be it a sail boat or a motor sailor, it seems particularly advantageous to have the ability to instantly reef the sails, or to lower them completely without any fooling around.


Battens: Many types of battens have been tried, varying from the obvious use of wood, to the use of ABS pipe, and then to the use of fiberglass rods or bars.
Proportion: The junk sail drawing shown at the top of this page is very generic, and is intended primarily as a schematic of a four batten junk (upper yard and boom not included in the batten count).
This letter was received from the current owner of Migrant, one of the vessels mentioned above. It was nice to come across your piece [above] on the Junk Rig and immediately see Migrant named and another story about Dick Johnson told.
I bought Migrant from Dick in 1991 after having sailed on her a number of times since meeting him in 1971 when he first sailed into Bellingham. I spent a year and a half in Mexico before sailing onward to French Polynesia, Samoa, Tonga, Fiji, the Marshalls, Micronesia, down to the Solomons, Vanuatu, New Caledonia, and Australia.
By that time the sun damage in the lower panels was severe enough that a careless push with my hand would go right through the sail. What other rigs exist where a rip in the sail is not of any great concern, or that you would be able to continue onward for that many miles using sails with cloth so old and fragile? If you do not participate in regattas, but want an easy handled rig for safe cruising, you should value the Chinese Lug rig.
The camber will develop in the lightest of wind, but will not increase in stronger wind if the battens are stiff enough. Regarding the tacking angle, it is important to remember that it is not dependent only of the sail, but just as much of the design of the boat and the keel. This series brings together a unique combination of traditional and modern elements and produces a range of boats optimized for offshore safety and comfort, ease of handling, excellent accommodations, and high performance of the type that is valuable to cruising people. 1.) Modern heavy-displacement hull designs of the full-keel type, for best comfort at sea, good steering characteristics under all conditions, and consistently high speed, especially in very light and very heavy air and on long passages. 2.) Chinese lug rig for full sail-handling capability (raising, lowering, reefing, unreefing, and sheet handling) from the helm, without touching the sail, optimum sail area under varying conditions without changing sails, consistently high performance, especially on passage, and low-tech simplicity and reliability.
3.) Flush deck design for maximum interior volume, ease of interior customization, versatile and roomy deck space, strength, and simplicity. 4.) Steering and sail handling from on deck or from the shelter of the enclosed steering station. The combination of the easily handled rig, the wind vane and the enclosed steering station is virtually unavailable elsewhere. It is very rare to find a line of live aboard voyaging yachts designed by a designer with as much live aboard experience as we have.

But it will be easier to get it already done to fit that boat in SS, than to design and weld it in AL.
It seems to offer an easily portable boat that is stable, seaworthy, can carry dive gear and can be boarded from the water. I’m not sure if it will take two divers but further testing will show its full potential.
For example, just as with a traditional gaff rig, one will be handling soft lines rather than harsh stainless wire and winches. By then I had put four more years in the tropical sun on the same sail cloth, and it had become very fragile. In the olden days, the canvas was stretchy, so it was hardly necessary to sew in camber in the panels!
It works together with the lazy jack, catching the bundle of the sail when you are reefing.
It is going from the fore end of the yard, around the mast, back to the fore end of the yard, via a block to the deck. The distance between the fastening points must be big enough to allow the sail to swing forward the desired distance. When the boat is tacking, the sail is hauled as far aft as possible, and when running, the sail is slacked off, so a greater portion of the sail is forward of the mast. We feel they revolutionize the experience of long-term cruising and voyaging, by eliminating much of the physical discomfort and many of the common dangers.

However, most of the diving around the coast requires a boat and this can be quite expensive so I have been looking for an alternative.
From what I have read, they are also fairly fast in the water and can cope with tidal currents and fairly rough seas. You can achieve that by introducing gussets (structural reinforcement ribs) under the top of the saddle, as it was done in the commercial W500 kayak. I have never designed a boat before let alone built one but the w Kayak concept looks ideal for my purposes. Hulls will now be 10 inch wide by 16 inch high and the seat 10 inches wide positioned on the top between the hulls.
However, I tried very hard to capsize it today and it never looked like getting close to it. If the batten parrels are too short, they will more easily catch when running up and down the mast. They have enormous deck space for best enjoyment of good weather, generous interior accommodations for the cost of the vessel, and maximum comfort and safety when conditions deteriorate. Further because of our great affection for this particular series of designs we have gone back year after year adding details to the plans and refining elements as suggested by our own thoughts and experience and that of owners of the vessels.
I have seem cheap ones and they look cheap, and well built ones that look like works of art, both in AL and SS.
The guy that does welding for me and Atlantic mention link above make beautiful welds and can even make them invisible. Why not built something bigger for live aboard ?Traditional Malay or Bugis boat are cheap to built in Indonesia and Malaysia.. Sails, with a low Aspect Ratio of 1.5 like this, is ideal for reaching and running, and therefore for working with the monsoons.
However, all other recommendations in the book are sound, and probably the best place to seek basic knowledge about the modern Chinese Lug. It will save a great deal of money in chartering boats whilst allowing me access to some dive sites that I can’t reach from the shore. After too many years of guessing, dominated by people who believed that some sort of turbulence produced lift in the Chinese lug, Junk Rig Association decided to pay for some research at the Exeter University.
The upper batten had a tendency to get an S-form around the mast when the wind came from the port side. With this method, you may choose more freely the point of maximum camber, and it is probably the best method to choose, when starting from scratch. I’ve nearly finished designing a 12 footer that should carry two divers and cylinders. If you have a heavy boat, and need more camber to get maximum power, you should use two hinges in each batten, but not to near the mast. I have incorporated most of what you say in my design but I reckon I can save some weight and retain rigidity by incorporating the under saddle gussets.
Here in the West people, for a long time, believed that all Chinese sails should be flat, and that they generated lift in another mysterious way than other sails.
It is not important how the camber is created, as long as it is practical, safe and don?t make it more difficult to reef. I don?t understand why, because I have seen old pictures of Chinese sails that are obviously not flat. Vincent Reddish was the first person I know of, that was talking about camber in the panels. In China it was usual to have bundles of bamboo aboard as spare parts, and for using as additional stiffening of the sail in stronger wind.
