YUZHANKA: BOAT UNDER SAIL…

YUZHANKA: BOAT UNDER SAIL...Every year, more reservoirs becomes “closed” for motor boats. What in this case do Amateurs vodnomotornyy tourism? To put their vessels on the joke? In any case! It’s time to recall the sail. Sailing rig can be a real alternative to a rattling, smoky, polluting water bodies with suspended motor.

 
The feeling I experienced putting a sailing rig on his boat “southern”, not describe. It must know myself. Instead of a motor noise I was suddenly surrounded by silence, and broke it only the rustling of the water over the side Yes the whistling wind in the rigging.
 
Within five years of operation sail well established. The conclusion is obvious — the basic engine of today needs to be a sail and outboard motor can be left only as an auxiliary tool.
 
The first thing you need to have on the boat to sail and with the wind and against the wind — tacking is turning the keels, or as them still name, additional parts, which significantly reduce drift boats — drift.
Additional parts are made of boards with dimensions 15Х400Х135 mm. at the Top they are fastened with rail 15X25X400 mm, the middle of a piece of wood 40X40X400 mm — additional parts they rest on the side of the boat. At the bottom of each. the turning of the keel with screws secured load — steel strip 15Х80Х400 mm weight about 5 kg,.— he needed to swiercz didn’t come up. On the top are fixed two metal plates 3 mm thick with hole Ø 21 mm designed for attachment to the cross member.

To lift sverzov each have holes, in which skipped the nylon ropes. Their second end is laid in the boat for a duck. The front and rear edges streamlined.
 
The crossmember is a steel rod Ø 20 mm and a length of 1360 mm. on both sides in areas of 100 mm is threaded. Additional parts must be mounted on the cross member, and each clamped between two nuts.
 
When a strong emotion between the rotary fins hydrodynamic forces occur, so use by both surcame not worth it. It makes sense to lower left swiercz, if the boat is port tack, and, conversely, the right, if the wind is blowing to the right.
 
The transom of the boats need to be refined. His plane should drill a hole Ø 6 mm for hinges steering. To position them it is necessary so that they do not interfere with the hanging of the engine. Holes mate loops in balerna box serverlists in place, in accordance with the location of the holes on the transom.
 
Mast sailboat wood, glued together from two boards with a length of 3050 mm. of Its cross-section at the base is 70X70 mm diameter at top 55 mm At a distance of 50 mm from the base of the mast, drilled a hole and inserted tube with an inner diameter of 10.5 mm — the bearing of the hinge of the mast. On top of the mast fits over the clip — end for fixing it guys, the forestay and headsail.
 
Balerna box arches of galvanized steel sheet with a thickness of 0.9 mm. dimensions of the sheet — 400X600 mm., First marked and drilled holes for hinges and blacked out Windows for tiller and sarlina. Box is clipped to the dimensions given in the figure. Between her cheeks to insert a strip of the PCB and attached to it by screws M5.
The rudder is profiled in cross-section, cut from a Board 10 mm thick. it Is located between the cheeks balarney boxes; the axis of the bolt 8. Back on it the drilled hole to secure Carlina, then it passes through the unit and into the space between balerna box and pen. At the opposite end of Carlina a ring that, when raising the rudder is laid inside the boat.
 
Sailing rig of the type “Gately sloop”. The area of the main sail — mainsail — approx 10 m2. It went about 18 meters of fabric. I recommend to buy a thin and durable material that has sufficient airtightness. When choosing fabric, use a simple “test”: apply the flap tightly to the lips and blow strongly. You will only fit this fabric, which is practically not blown. This Pillow tick, reps, cloak-tent. Also suitable percale fabric and Bologna. Before we will open the sails all the material is soaked for several hours in water and then dried and smoothed. In the middle of the cloth at full length prostrochite fallow a width of 30 mm. To do this, fold the cloth in half and smoothen the crease iron. Next, having measured from the bend of 30 mm, it is necessary to neaten the seam, and then stitch this line on the sewing machine. Then stitched the bent part, and there are still two lines.
 
Begin cutting the sails. The length of the first two pieces of 3 m. They are formed by the edges and sewn together, then the seam allowance is folded aside and made another seam.

Now spread received double the cloth on the floor and with chalk on the first piece, apply the diagonal (Fig. 4). Then the second piece is lowered perpendicular — it will serve as the axis of the front foot. On the diagonal is cut to 1/3—1/4 of its length from the tack angle, and perpendicular to it is delayed the greatest convexity of the lower luff of about mm. Convexity luff point — circle curve. Cut off the excess material and you are ready to add the rest of the panels of the sail.
 
Cutting off pieces of material, keep in mind that overlapping of the sheets shall be not less than 50 mm. At a height of 1700 mm from the front (tack) corner is cut length of 50 mm under the jaw. The axis of the upper leech point is located at a distance of 450 mm from the axis of the front foot. The greatest convexity luff point is about 100 mm.
 
After sostragivaja all panels lay next sail on flat ground, cut all the edges and panel strip of fabric with a width of about 100 mm. Corners of the sail stress — tab on them scarves made of thick material — booty. To Katarina sail is sewn of nylon rope. To sail better keep in shape, it has armor — flexible wooden plate with a thickness of 3 mm, located in latterman. Similar to the grotto cut out n the headsail — staysail.
 
Of course, the “world” with the sail not sports yacht, she has a fairly large resistance, and when the crew in the four man heavy. But nevertheless it goes pretty well, and I’m sure if you follow my example, you will get tremendous satisfaction from the sails and hopefully completely forget about the motor.
