    well back at it, here in the cold weathers of chicago.


    the sail I have made is a 305 square ft. Split junk on top of a 2.5 tun displacement of the contesa 26. I plan to go on many dangerous Adventures :-)

    I am extending a 27' tapered lap post with a .188" wall up an additional 6' 6" using a pole measuring 5" OD with .125" wall. I will be setting 2 ft of the 5-in pole into the lamp post and Welding or epoxy in it into place.

    I am having difficulties coming to a conclusion for a final height of the mast. my questions are as follows

    height of mast above deck before the lowest Batten on the sail?

    height of mast above the yard? ( I will be using a five piece tackle for Main halyard)


    for my batons I'm thinking inch and a half schedule 40 T6 aluminum which equals 1.9 inch OD by .145 in wall AKA 48.26 mm OD 3.683 mm wall

    for the top most baton, the one just below the yard. I have a 2-in schedule 40 pipe AKA 2.375 OD by .154 wall or 60.3mm OD x 3.9mm wall


    I'm kind of stuck on the yard. I am in between getting a 4-in pipe with a 1/8 in wall AKA 101 mm OD by 3.175 mm wall


    the alternative would to do the Arnie yard and put two pipes together. but I'm having a hard time finding a smaller aluminum pipe that isn't crazy thick. I'm also looking to get some literature on building and rigging the yard for a split junk. if anyone can point me to some literature, it would be much appreciated :-)


    I'll be spending more money on aluminum than I did on my car, any reassurance would be a gift :-) :-)

    Howdy y'all

    Thought I'd check and give you a quick update. My sail is all done with. Got a couple lacing gromits to put in but other then that... 

    Making a second attempt at my lower mast partner. I think I have got a better idea on how to cut out an octagonal shape. This time I will be using a router instead of a jigsaw. 

    Today I will be making some shims for the thing.

    The wether here in Chicago is looking up. Still not warm enough for epoxy thoug, won't be much longer.

    I will be taking a break from building soon as I will be out hiking this year. I got 3,600 miles to cover on foot through the Rocky mountain range in central United States. From the Canadian border in Montana to the Mexican border in New Mexico! 

    If the mountains were the sea, high up on the Waves is where I'd be!

    After that I'll be dragging the boat down to Florida to finish he up! 

    All the best till then

    David, where do I find the rest of the album pics in members sidebar? Following all this with awe at the knowledge base on here.

    Jeffrey, have a look at this photo album. Photo 5 gives proportions for a pocket for a 32mm dia batten, which you could scale to another size.

    No. They are called D shaped pockets because the vertical straight side is the sail and the curve allows for the top, bottom and other side of the batten. Allow a bit extra so that the batten is a little loose in the pocket.

    All the best with the project, David.

    Time to start cutting out some fabric!!!

    A couple of questions about batten pockets before I get going.

    I'm going to be using the D-shaped pockets. I would assume that I will need to add a bit of extra material into the sail to accommodate the thickness of the batten. My thought is to add material 1/2 of the circumference of the batten, or 1/4 of the circumference to the batten edge of each panel

    Then make the pocket "strip of material" the with of the other 1/2 of the batten circumference "+hem and a little bit of slop"

    Is that the way to do it? I'm having a hard time finding information on this.

    Thanks David and David!!!

    I'm going to go with the top gun 9. Seems to have a good record with both durability and sewability. I'm going to order something like twice my sail size in material. I'm assuming there is going to be a good bit of waist and majority of that from learning curve. Blue and white will be my collars and I'm excited to talk further about beefing up the top 2 panels. If anyone can recommend some literature on that...

    David, we made the pair of sails for Footprints and Tystie from Hayward's Sunwing polyester cloth, which sadly is no longer available. It had UV protection - few regular sailcloths have this, and are not a low cost option if they do. I wouldn't use regular polyester sailcloth (Dacron and Terylene being brand names for the polyester fibre from which sailcloth is woven, not the cloth itself) for a cruising junk sail, unless UV protection was built into it. I would want a softer cloth that is happy to be left uncovered when not actually sailing.

    Jeffrey, Weathermax 80 is a good cloth, but is a bit tricky to sew. Topgun 9 would be a good choice. In your position, I'd be looking at  this and this . I've always had good results making sails from second grade cloth, as the flaws are generally cosmetic, not structural.
