UNDER SAIL OR MOTOR

UNDER SAIL OR MOTORMotor-sailing ship (PMS), about which speech will go, was built on the basis of the finished hull of the prototype of a torpedo boat, scale is 1:4. Housing layout with a length of 7.4 m at the waterline almost got me at a knockdown price, when in the middle of 1980-ies in the process of the next environmental campaign cleaned the shores of the pirogovskoe reservoir near Moscow. Much effort and financial investment, the restructuring of the layout of the boat in motor-sailing vessel is not required. But I with the case, you can say lucky. For those who want to build the same or similar, here is the description of the design of the whole body, with explanatory drawings.

First, a few words about the technologies of building the vessel from scratch.
 
Before the production of each of the frames, proceed as follows. He first plotted full-size on the Plaza of a suitable sheet of plywood. The frames are made up of separate elements made of pine boards with a thickness of 20 mm, which are fastened together at the overlapping or gussets, epoxy glue, screws, and if necessary — and additional bolts.
 
To build the hull of the individual elements is mounted to the slipway. Set on the slipway the keel-beam and fastened to it with epoxy glue and screws, pre-fabricated frames. The ribs connect the longitudinal force elements. Then perform the shell plating.
Describing the ship, from the outset, it is — cabin type. His entire power set — wood paneling — from bakelizirovannoj plywood covered with a thin layer of fiberglass.
 
The ship is divided into five compartments. The first of them — the forepeak is separated from the subsequent water-proof (“broken”) bulkhead fitting, located on the sixth frame. To access the deck in forepeak tank is arranged a hatch that closes a hinged lid dimensions 700×670 mm, made of clapboard and covered with glass fiber epoxy resin. On the hatch mounted vent fungus.

Aft extremity of the ship
 
The aft extremity of the boat (the transom of the vessel with pantograph):
 
1 —BIMS (upper tie bar) of the penultimate frame; 2—transom; 3-deck plating; 4—tiller (stainless steel, tube Ø20 mm with an inner diameter of 8 mm with stopper, bolt diameter 10 mm); 5—rudder (steel, circle Ø29); 6—Bellerophon (stainless steel, pipe Ø31×29); 7—washer (steel); 8—bolt (steel, Ø16 mm, L100 mm) for mounting the tiller on the rudder stock; 9—transmission system of ropes and blocks (steel), for duplication of the steering wheel using j; 10—keel block; 11 —deck the lower deck; 12—sliding bulkheads (plywood, s6); 13—last frame—felines (oak Board section 120×30 mm); 14—thrust rail bellerofonte (oak, 100×60, attached with epoxy glue and screws to the last frame); 15—fuel tank 180 l (duralumin); 16—wooden stand for the fuel tank (attached to the frame screws); 17—guides for the sliding bulkheads (wood); 18 — an arm; 19—steering compartment; 20—cockpit; 21-mounting bolts M8 for mounting the frame of the pantograph to the transom of the vessel and the under engine plate (steel, L100 mm, 8 PCs.); 22—sub plate arm; 23—rudder (stainless steel, plate 600x500x10); 24 rotary rudder (stainless steel, plate 600x500x10); 25—axis rotary rudder (steel bolt M10, L30); 26—the halyard to lift the rudder; 27—outboard motor; 28—regular screw clamp outboard motor

 
Pantograph
 
The pantograph (a hinged motor mount):
 
1—machine bed (aluminum, plate 200×100, s40, 2); 2—lifting bracket (stainless steel, strip 320×40, s7,2); 3 —focus (stainless steel, strip 320×40, s7,2); 4—bracket (stainless steel, strip 320×40, s7, 2); 5—sub plate (PCB, plate 300×300, s40); 6—reference axis of the hinge (pin М10х170, 4 nuts M10, 2 washers, 2 spring washers, 2 cotter pin, 2 sets); 7—an axis of a hinge (pin M 10×150, 4 nuts M10, 2 washers, 2 spring washers, 2 split pins, 2 sets); 8—axis handle (hairpin М10х170,4 nuts M10, 2 washers, 2 spring washers, 2 pins); 9—handle (tube Ø13×1,5 with outer notch); 10—coupling support brackets (М10х160 stud,2 nuts M10,2 pin); 11 —spacer (2 PCs.)

 
Next compartment — saloon. There is a folding table attached to the pillers along the sides — two: upholstered sofa lockers: one under sail, the other — under the life jackets. When the unfolded table in the cabin can rest 4 persons and 2 persons in the forepeak (only 6 people).
 
The third compartment is the galley. In it, starboard, a Desk with a gas stove. The gas is fed through a hose from a five-liter container installed in the next compartment in the cockpit. In the table, lockable sliding doors, stored food and drinking water in two ten-litre cans for long trips. In the galley there are two chairs. In the bulkhead between the galley and the wardroom has a large hole (a height of 1500 mm and width 900 mm) and the bulkhead is more of a portal, canaveruelas curtain. Cabin and galley located in the wheelhouse, and both compartments can germetizirujut by battening down the front door
 
Next is the cockpit dimensions of 1.5 x 1.5 m. Hence the management of the sails and by the vessel. Here are the two seat lockers, one on the starboard side — the whole length of the cockpit (it contains gas bottle, battery, water storage and four Krantz) and a small in the left rear corner (this retracts the anchor and the rope, the lifting anchors is done by hand). This compartment is open, but if necessary, in the rain or bad weather, closed canvas top.
 
The last compartment after peak, a small. It is separated from the cockpit sliding partition. Behind it is the fuel tank 180 liters. Top deck closed stern sections forming Ute. Below deck are located the cables and rollers of the steering, as well as the score EP and tiller helm overlooking the cockpit
 
Can’t tell which engine was designed the boat, but the layout had a water cannon. Initially the boat was planning to put a stationary engine, only replacing the propeller on the propeller.
But soon we adopted the state program on protection of water bodies from pollution, which obliged the owners of small vessels to alter motor boats under sail. It had to rebuild the housing layout of the boat, if possible closer to the design of the hull.
 
In the front of the case there was a forecastle — 200-mm elevation above the level of the rest of the deck. I left him. Everything else: the wheelhouse, the deck from forecastle to poop was removed. Dismantled and stationary engine.
 
On both sides over from the stern to the forecastle arranged sirtrack — top gains the zone boards. For this sangeotoy increased to 180 mm (to the level of the forecastle beams of larch lapped epoxy glue and pulled them further bolts. The upper ends of narusheniy frames combined corner (between the side and deck) stringer section 60×20 mm (Board of larch with a length of about 6000 mm) by inserting it into pre-cut the slots in the ribs of epoxy glue and screws.

Power set case
 
Power set of the case:
 
1 Kil (oak); 2—stem; 3—frame (larch); 4—beams (larch); 5—inner fender; 6—bilge stringer (larch, timber 40×20, 2), 7—carlings (larch, Board 100×20,2); 8—polubes (larch); 9—famines; 10—front of the bench; 11 —beam stocks

 
Frames
 
Frames:
 
1 Kil; 2— Flor; 3—frame (futex); 4—bilge stringer; 5—BIMS; 6—probems; 7—carlings; 8—fender; 9—knize (plywood s6)

 
Stepping the mast
 
Steps of the mast:
 
1—plain bearing (epoxy plywood s10); 2—the base (aluminum, sheet s12); 3—cheek (made of anodized aluminum, the sheet s12, 2); 4—cradle (made of anodized aluminum, the sheet s12, 2 PCs.)

 
The keel
 
The keel (the material details of the positions 1, 2, 6—armor plate s12):
 
1 —the wall (2); 2—bottom; 3—ceiling (steel strip s20); 4—skiing; 5—bolt M20 (4 piece); 6—ballast m=350 kg (lead pig); 7—rear prismatic wall

 
On felinese the last aft bulkhead of the hull layout was mounted to a vertical transom is made of epoxy plywood 10 mm thick. (frames and transom) is also converted into a “yacht” stern. From the transom at the top left rectangle a height of 300 mm To the bottom edge of the transom docked at an angle of 60° into the vessel from the vertical, another sheet of the same plywood pre-cut according to the profile of the sides and bottom. Pre-altered and lower part of the rear bulkhead.
 
The penultimate frame closed at the top by cross-beams (boards of larch-section 100×20 mm and length 2000 mm), cementing them with epoxy glue and screws. From the crossmember to the beams of the forecastle mounted on both sides symmetrically at a distance of 750 mm from the diametral plane a pair of longitudinal beams below the deck — carlington from planks of larch section 150×20 mm and a length of 5500 mm Carlings to beams attached with epoxy glue and screws through the wooden bars mounted in the ends of carlings. Between Burlingame and extended parts of the frames on both sides mounted polumesy — wood short of the cross member, and attach them to those other elements with epoxy glue and screws. Then olubisi epoxy glue and galvanized screws attached deck flooring waist (lining-section 100×20 mm and a length of 6000 mm from the forecastle to the transom). The same lining (deck flooring), but short 500-mm segments blocked and the rest period between Burlingame from the next to last crossmember to the transom.
 
For extended parts of the frames from the forecastle to the transom outside on both sides staged sirtrack — top (additional) reinforced belt side plating of 6 mm plywood with a width of 200 mm and a length of 6 m. It was performed back to back with the existing casing and attached to it with epoxy glue and to the frames — and even screws.
 
Then around the perimeter flush with the deck flooring was attached to the corner of the stringer with epoxy glue and screws fender bar from a larch section 50×40 mm.
 
Descriptions of the above alterations here is to help those who may face the same necessity.
 
Inside the housing mounted on the bottom and glued to it with epoxy to the keel — beam of oak timber section 180×100 mm and a length of about 6.5 m, to which is attached a flora from all frames. Flora laid on flooring of the 20-mm boards larch (width of boards 150 mm).
 
To the keel and the keel four steel bolts M16 with a length of 250 mm is attached to the keel with a length of 3700 mm and a height (depth) 410 mm, made of 10-mm steel armor plate. The keel is a welded narrow box with a thickness of 100 mm, with cut of in front of under 30°. Box welded to steel plate sizes 3700×80 mm and a thickness of 20 mm inserted in her four M16 bolts for mounting to rudder (and keel). From the bottom to the box welded to the bottom — a strip of steel armor (2700x100x10 mm). The weight of the boxes was 150 kg But for reliable stability of the vessel could not be enough. Therefore, the box keel decided to populate additional ballast. To do this in t-beam width of 115 mm, as in the trough, the fire melted the lead and solidified ingots with a total mass of 250 kg put in a box keel. Rear opening boxes are closed (welded) prism (converging lines) of the steel sheet. After that the keel was connected to the case, standing on a wooden bench, and two jacks are raised to the bottom. Four bolts M16 vnatyag with epoxy glue inserted into pre-drilled corresponding holes in the keel and the keel, and was provided with a sealed enclosure and loose keel.
For the device logging on both sides to carlington attached with epoxy glue and screws wall — sheets bakelizirovannoj plywood size 4000×700 mm and 10 mm thick to a height of 600 mm from the deck and down to the edges of the Pre-carlington at the walls and the front edge is cut at 25° to the vertical and docked here a frame of wooden bars to front Windows.
 
Inside the room is installed vertically bulkhead-portal — (plywood) that are attached to the frames of the roof of the cabin, on which is laid the roof (on epoxy and galvanized screws, Board, boards 3500x100x15 mm). In the side walls of the cutting is cut along three rectangular holes size 700×350 mm under the Windows. After that installed pre-prepared Windows made of organic glass thickness of 6mm for the sealant to mount the bronze screws.
 
Input rear bulkhead of the wheelhouse, mounted on epoxy glue and galvanized screws (lining 1000x100x15 mm, 450x100x15 mm height 1585 mm). In it, on the left side, is arranged in the door with the same window. A similar window is arranged on the right side of the bulkhead before the working steering.
 
As for the case finish (or rather, training it under a coating of fiberglass), it is traditional for wood products. The body parts are aligned (where required) epoxy putty, polished with sandpaper, vacuum, wipe with acetone and covered with two layers of fiberglass with epoxy. Do not immediately seal the entire housing. Easier to do it consistently. For example, glue one or two longitudinal belt after curing of the adhesive process them outside, and then glue the belt.
 
The final (surface) finish fiberglass coating includes again, grinding with sandpaper, remove dust with a vacuum cleaner and rinsing with acetone. In conclusion, the surface is primed and painted with enamel.
 
On transom mounted pantograph, which by means of the handle allows you to install outboard motor in the operating position “on the water” and outside — “out of the water” rearrangement of the lower ends of supports with a support axis of one plate to the other when the boat is sailing or docked.
 
The rudder was composite, the lower movable part (stainless steel sheet size 500x600x10 mm) can be rotated around axis and up as arbitrarily (in the shallows and underwater obstacles), and skerton (when mooring). The wheel can be controlled by tiller or wheel through a system of flexible (cable) wiring and rollers.
 
On the coach roof handrails are installed along its entire length (the dural tube outer diameter 20 mm) on aluminum holders and a shoulder strap geek.
 
According to the calculation of the alignment of the sail, the mast had to be set at a distance of 3.5 m from the bow of the boat — right at the top of the cabin. There was mounted the steps — a box with dimensions of 150x150x150 mm of duralumin 12-mm sheet with drilled holes in the side walls — 20 mm in diameter for attachment of the mast when setting its bolt M20 length 170 mm through a corresponding hole in the end. Under steps, inside cabins, installed pillers (titanium pipe outer diameter 60 mm and wall thickness 5 mm), with emphasis on the keel and, accordingly, the keel.
 
The scheme of installation of the mast
 
The scheme of installation of the mast:
 
1—the bow attachment point of the forestay the mast; 2—forestay; 3—hinge of the boom; 4—rear end of the boom; 5—gik; 6—steps; 7—bolt support mast; 8—aftersteg; 9—lengthening of the umbilical cord achterstege; 10—sweathouse node between achterstege and lengthening of the umbilical cord; 11 —side guy (2); 12—attaching the side shrouds into the deck (2); 13—stretch when installing the boom (2); 14—fixing achterstege on the deck; 15—mast

The concept of lighting and light-signalling vessel
 
Mast made of duralumin tubes of an external diameter of 120 mm (wall thickness 3 mm) with a length of 8 m. To the mast, almost throughout its length (7.5 m) attached by self-tapping screws lik-groove is cut lengthwise with a hacksaw, 3 mm wide dural tube an outer diameter of 20 mm (wall thickness 2 mm).
 
Further, the slit was closed dural wedges to a width of 5 — 6 mm (diameter countersunk head screw, self-threading). Through this slit is drilled right at the same time in likasi in the mast hole at a distance of 200 mm from one another. Holes in lipase was Zenkovich and screwed self-tapping screws. After the final mounting slot edges were blunted, and its width is restored to 3 mm.
 
On the lower part of the mast (at the steps) put the clamp (dural band, 50 mm wide and 4 mm thick) on which is pivotally suspended from the oak boom with a diameter of 80 mm and a length of 3.5 m.
 
Sailing rig, consisting of mainsail and headsail — purchase from a sport yacht of the type “Dragon”: total sail area — 22 m2 . The grotto is associated with the shoulder strap (dural strap size 1500x60x6 mm), reinforced with epoxy glue and screws on the roof of the aft superstructure through the substrate (strip waterproof plywood size 1500x30x10 mm) using a slider that moves along the entire length of the latter. The tether boom, through the blocks between the slider and the boom and wound on a hand winch mounted on the bulkhead of the deckhouse, which allows you to control mainsail effortlessly from the cockpit. FAL lower luff of the headsail can also be wound on the winch and fixed stopper backstay headsail, it is possible to manage and staysail depending on the strength and direction of the wind.
 
Standing rigging and halyards made of stainless steel ropes (cables). Around the cockpit on the deck and the wheelhouse are located Shkotovo winches, stoppers, blocks and cleats for tackle rigging. In addition, on both sides of the cockpit are mounted two cleats for mooring.
 
Setting the masts of a ship carried out in the following way.
 
The mast is laid horizontally along the boat and secured in steps axle-bolt through the hole at its base.
 
Further divorced from her weight to where it mounts on the deck to which they are hooked via lanyards.
 
Gik is fixed on the clamp at the base of the mast is mounted vertically (at 90 degrees to the mast) and “stretched” the lines on the sides.
 
Aftersteg lengthened the halyard from the mast through the rear end of the boom start to the stern. Tension achterstege hands towards the stern the mast is set upright. Side guys contribute to its retention from the stall to the side when lifting. Then from achterstege untied lengthening the halyard and its end attaches through the lanyard on his seat in the stern, and pulling on the forestay.
 
The ship is equipped with all the equipment provided by the rules. Lighting in the middle part — at the expense of the Windows at night from the battery lamps in the ceiling of the cabin. The battery can be recharged from the generator outboard motor.
 
Running lights (red, green, white) — mast mast.
