8. TEMPLATE MEASUREMENT

To allow a Sabot to be registered it must be measured by a club or association measurer, who will complete and authorise the association measuring certificate, a copy of which is included. This measurement will be done with the assistance of a set of association templates. To assist in assuring that the Sabot will measure in, the measuring procedure is explained below:

8.1. Hull is to be inverted but not necessarily to lay level.

Keel - apply straight edge to keel line measuring 110mm from underside of straight edge to keel on stern station with the following measurements to apply at the nominated stations.

 

Note: Station 4 on straight edge to coincide with datum point on hull.

Station Stern 110 mm datum measurement - no tolerance

Station 6 28mm plus or minus 8mm

Station 4 6mm to 0mm

Station 2 78mm plus or minus 14mm

Station Bow 205mm plus or minus 21mm

 

When the straight edge is in position the angles of the fore and after transoms can be checked by projecting the angle lines as marked on the straight edge, also the length of keel by projecting at right angles from the straight edge.

Chine widths and Vee Sections - apply templates and measure depths to sheer at the same time. Refer to table in 2.2.3 for dimensions.

8.2. Beam at Sheer - Turn the hull right side up. Apply other side of straight edge to check length and station positions. Use templates to check sheer widths at 2,4 and 6 at the same time the straight edge is in position check the position of the plate case and length of the foredeck.

8.3. Forward and After Transoms - Apply templates. The transoms must be within +/-6mm of the templates all around.. When in doubt over any dimension on the templates, refer to 2.2.3.

8.4. The tolerances on the hull are - plus or minus 6.5mm on the half breadths and 13mm on the depth of side measurements. Plus or minus 6mm in the depth of Vee sections of the hull at 2,4,6.

BUILDERS GUIDE

THE AUSTRALIAN SABOT

As the Sabot can now be constructed of many varied materials, it is difficult to advise an intending beginner how to select a suitable Sabot to learn to sail. However, in this brochure, we have set out the steps to build a timber and plywood hull and spars, which can be built by an amateur, using basic tools on a frame which in some areas can be borrowed from the local Sabot authority.

If you require more sophistication you should inquire from a local boat builder, who will advise you on the other types of hulls available - such as glass fibre, foam sandwich or stitch and glue kit.

Notwithstanding the method used to construct the hull, all must "measure in" to the requirements of the Council’s Rules of Measurement and as summarised in the measuring sheet extracted from the rules of measurement and attached at the rear of this brochure, so please don’t skimp; do your paper work first and you will avoid many problems later.

The purpose of the restricted measuring is to provide equal sailing opportunity for all competitors and the measurements are not to be modified in any way from those allowed, otherwise you may find your boat will not qualify.

SABOT BUILDING PROJECT

BUILDING INSTRUCTIONS FOR SABOTS

Section A - The Building Mould

Materials:

1800 mm x 1220mm x 10mm ply or 12mm pyneboard 1 sheet

100 mm x 50mm 3/2.7M

50 mm x 25mm 4/3 M

 

Construction:

1. Mark out the two rails according to the plan to take the moulds and the transoms. Connect these with the mould supports. Check that the rails are parallel and that they make a 380 mm wide frame. Check also for squareness of the frame.

2. Cut the remaining rail into four legs, fasten them to the frame and brace the bottom of the legs.

3. Fasten the transom supports.

4. Mark out the three moulds, remembering to subtract 4mm - the ply thickness from the sides and the bottoms. Then mark out and cut out checks for keel, chines and saxboards.

5. Fasten the mould to its frame.

6. Blocks 20mm x 20mm (approx) about 50mm long may now be glued and screwed to one side of the moulds, about 6mm away from the checkouts for the keel, chines and saxboards. These may now be drilled with a 4mm bit, at an angle to allow for temporary fixing by screws of the keel, etc. from inside the hull - until the planking has been fastened home.

 

N.B. Have you remembered to double check all measurements before cutting and fixing? Fixings can be nails and glue or screws.

 

Section B - Building the Shell

Materials for an all ply hull

Marine ply sheets 2400mm x 1200mm x 4mm (suggested)

Transoms 44mm x 16mm dressed size 2/2.7M

King Plank & Deck Beam 95mm x 20mm dressed size 1/1.8M

Keel 70mm x 20mm dressed size ½.7M

Chines 25mm x 25mm dressed size 2/2.7M

Saxboards 20mm x 20mm dressed size 2/2.7M

Gunwales 20mm x 20mm dressed size 4/2.7M or 20mm x 12mm dressed size 6/2.7M

 

 

Timber Range(Suggested)

Pacific Maple, oregon, spruce, cedar, silver ash, king billy, huon pine, meranti, balsa, are all suitable timber for building, but others may be on the market - BUT be sure to specify timbers suitable for bending.

All materials to be of good quality, light, clear and straight grained.

Fastenings (Suggested)

16 mm x 1.6 mm Monel boat nails or silicone bronze 60 grams

30 mm x 2 mm Monel boat nails 150 grams

30 mm x 8 G counter sunk brass screws, monel or s/steel

38 mm x 8 G counter sunk brass screws

 

Marine glues - either formaldehyde, epoxy or resorcinol - approx 1 litre.

It is recommended that a two pot glue be used.

 

N.B. Ply timber and fastenings should be sufficient to finish the hull. When ordering the timber some thought should be given to the different colours available. Perhaps a visit to a local Sailing Club will allow you to see the rather striking effects made possible by the use of various coloured timbers.

1. Transoms - working from one end of a sheet of ply if vertical grain is desired - or from one side if the grain is to run along the transom - mark out and cut out the bow and stern according to the plan.

2. Using the 44mm x 16mm timber, cut out the framing to the shapes shown on the plan. Fasten to the inside of the ply with glue and boat nails. The nails should be placed 25mm from the edge of the ply to allow for the bevels. Distance apart of the nails should not be less than 75 mm centres, when working along the grain, but not more than 60mm centres when working across the grain. The gussets may now be cut, glued and nailed. For those with sufficient clamps the nails may be omitted.

3. When the bow transom is dry remove the bevels - about 10mm on the sides and 16mm on the bottom. The keel, chines and saxboards will need to be housed into the transoms. This housing can be taken through to the ply and can now be sawn and chiselled out. An alternative method is to leave the ply off the transoms, fixing the keel into the framing and gussets, then fastening the ply home. Watch the angles where the timbers meet the transoms.

4. After a final cleaning up they may be fastened to the mould transom supports by screwing through from the inside of the hull, taking note of the mould reference line.

N.B. All timber should have been planed and sanded to remove machine marks and imperfections before being placed on the hull.

5. Now check the length of the boat, this should be 2427 mm over the transoms. A 6mm either way on this measurement would be permissible at this stage of construction.

6. Keel and chines should now be partially bevelled where necessary, see the section at mould 4 on the plan, and, with the saxboards, should be cleaned and sanded on those surfaces inside the boat. Saxboard bevel should be left at this stage.

7. These timbers should now be cut to the required angles and glued and screwed into the bow transom, bent around the mould, and then cut, glued and screwed to the stern transom. Care will be needed with the chines and saxboards but unless poor timber is used steaming is unnecessary. Cramps will assist to bed the timbers neatly into the checkouts, screws through the blocks on the moulds keep the timbers in place but be sure to screw through the blocks into the timbers.

8. Fairing off - using a sharp plane and a piece of straight timber about 600mm long, the transoms, keel, chines and saxboards must now be bevelled to allow the planking to fit perfectly. Care must be taken not to reduce the timber sizes unnecessarily, or to develop flats in the chines between the moulds. Plane carefully and stand back some distance frequently to check.

 

IMPORTANT Before planking check these three points -

Mark in the position of the centreboard case, you don’t want nails where you have to cut the slot.

Mask off with tape any point where the glue could squeeze off the timbers on to the mould. You do not want the mould permanently glued to the boat.

Check that the saxboards will slip out of the checkouts in the mould when you are ready to remove the boat.

9. Planking - If you have access to a 2500mm length of paper (heavy) or light

cardboard, this can be laid on the bottom or side of the boat and one half of the bottom (some have found it easier to plank the side of the boat first) can be marked on it and cut out. Transfer this shape to one sheet of ply - the complete bottom will come out of one sheet - leaving a margin of 25mm all around at this time and then cut out Bend the ply around the mould and plane the sheet to fit the centre line of the keel, now turn over on to the other side of the mould and if the shape is the same, lay the now correct shape on the other piece of ply, face to face, and mark out the pair of planks. Return to the mould and mark the centre plate case position. Now spread the glue on the timbers on one half only, place the sheet carefully on the glue, tack into position with selected fixings, working out from the centre along the keel and chine. The nails should be in the centre of the timbers of the transoms and chines about 20mm in from the centre line of the keel except around the plate case, they should be 25mm in at that point. Watch carefully the angles to place the nails, particularly forward where the chine and the transom are at quite an angle.

10. Trim the sheet with a saw and plane until the fairing is perfect, then treat the other bottom plank in the same manner, first making sure that the centre join meets correctly.

 

IMPORTANT Be sure to wipe off excess glue with a damp cloth as soon as each sheet is fastened.

11. Once the bottom or side planks are fastened the side planks may be marked out in a similar manner and fastened with a margin of ply overlapping all round. Don’t panic, I know that the sheet is short. Remember that piece you cut off the bow end of each bottom sheet, just cut a piece from this and butt it to the end of the side sheet at bow transom with a ply gusset behind it. You could splice this piece on but it is not really necessary. Now trim the side planks except along the saxboards.

12. Gunwales- These may now be fixed with glue and selected fixings without waiting for the glue to dry the next one may be glued and nailed. First be careful to mark the position of the gunwale on the ply to coincide with the saxboard. You may shape the edge of the first strip to bring the gunwales level as shown on the plan, or leave it square to allow the gunwales to be at 90 degrees to the side planking. The under bevel can be done later on. Total width of gunwales and saxboard to be 50mm min to 80mm max, 20mm of which must be inside the planking of the hull. The gunwales may taper evenly from 20mm to 12mm thick on the outer edge. Gunwales may not taper except from bow transom for a distance of 400mm, min allowable at bow transom is 25mm.

 

N.B. When nailing the gunwales place the nails nearer the top of the strips to

allow for bevelling.

Now leave the shell to dry for 48 hours and before completing the hull take a trip to one of the clubs sponsoring sabots. You will find that most of the boats there are owner built, or contact the Association Secretary, who will pass you on to someone knowledgeable in Sabot construction.

 

 

Section C - Completing the Hull

1. Undo all temporary fixings inside the hull and remove it from the mould. If it is tight, lever up gently with a wide chisel at each mould. If it is stuck - check that all screws have been taken out, then continue gently levering. Small spots of glue hold tight.

2. Now build a small carrying cradle from cheap timber shaped to moulds two and six. Pad and sit the boat in this.

3. Spread the hull to its correct widths at gunwale level at moulds:

No. 2 - 952mm,

No. 4 - 1144mm and

No. 6 - 1130 mm.

Remember that the measurements are to the outside of the ply. Tack the spreaders in to keep the hull to this shape whilst it is completed. Check overall length, keel length, spring of keel and section vees again.

4. Now fair the gunwales and the transoms to take the gussets and the deck.

5. Shape the deck beam and house it partially into the saxboards with the aft side between 662mm - 762 mm from the outside of the bow transom. Glue and fasten with screws.

6. House the king plank and deck beam to give bedding for the deck. Refer plan for alternative strong back method (see Sheet 2).

7. Shape a piece of 44mm x 20mm timber to shape of keel and fix in place. Fix a support between king plank and stiffener, glue and nail in position.

8. Fair off the king plank and deck beam to give bedding for the deck, or use strong back design (see Sheet 2).

9. Glue two piece of plywood 150mm x 25mm at 175mm minimum to centre line from Station 1 to act as strengthener for chain plate. Fit king post between king plank and keel, as shown on plan.

10. Next fit forward bulkhead, this will fasten to end of centre board case.

11. The simplest method to fit this bulkhead is to get a few off-cuts of 4mm ply approximately 50-76mm wide and fit around area where it is to touch sides and bottom. Fit two pieces around bottom checking out for keel and chines, then the same applies for sides, checking out for chines and saxboards, then another strip across the top. Fasten these ply strips together firmly with brads whilst they are in place. You then have a template which can be marked off onto the ply you wish to use for bulkheads, leaving enough ply at top for a 100mm camber, measured from points at the inside top corners of saxboards.

12. To fasten the bulkhead into the hull there are two reliable methods, firstly the simplest and a very reliable method is to hold bulkhead firmly in place, a strip of masking tape run around the joint from saxboard to chine: keel, chine and back to saxboard, then secure bulkhead permanently in place with approximately 50mm wide fibre glass stripping with epoxy resin. Another method is to fasten 38 x 12mm timber around forward inner edge of bulkhead, bevel off to shape of hull and fasten through hull with 16mm x 16 gauge Silicon Bronze or Monel nails and glue.

13. Cut the deck to shape, the gussets are part of the deck, and their shape and size are optional with maximum limit. Glue and fasten. Check that deck is between 666 and 766 mm long.

14. Shape the stern gussets, maximum size 200mm x 200mm. Glue and nail in position, the shape of the stern gussets is optional.

15. Construct the centre board case to shape shown on plan, nailing the ply from the inside on to the side logs first, then glue, nailing and clamping the sides to the spacers. Remember to give the insides a couple of coats of lacquer varnish before doing this. We suggest using 22mm max. spaces to allow the use of carpet for protection. The external slot is to be a maximum of 20mm wide.

16. Mark the position of the centreboard case on the keel. Place the case on the keel, and with an assistant to steady it, use a pencil resting on a 12mm square block to scribe the keel along each side of the case. Saw to the lines and then fit exactly. Top of the centre board case to be kept parallel with reference lines.

17. Mark out the length of the slot on the keel, drill at the ends with 19mm clean cutting wood bit until the point just breaks the ply, turn the hull over and finish drilling. Draw a line between the sides of the hole and saw out.

18. Fixing the case - it may be screwed through the logs onto the keel, or from the outside possibly easier. The case may be glued and screwed about 8 screws or use caulking compound and screws. Drill clearance and pilot hole for all screws.

19. If using thwart - cut and fasten in the thwart risers. Risers can be glued to the ply and fastened with nails from the outside. If not using thwart - one riser each side must be fitted, as required.

 

N.B. All timber should have been sanded to remove all machine marks before being placed in hull.

20. Turn hull over, bevel underside of gunwales as shown in plan.

21. Punch, fill, sand and lacquer or paint the hull now.

 

 

Section D - Centre Plate

1. From a single 280mm wide board about 1M long, if one can be obtained without twist or cup in it, or from two 140mm boards glued together, the centre plate can be shaped. First, have it run through a thicknesser at your local joiner’s shop to a thickness of 19mm.

2. Before cutting to length work out the type of stop and handle required, these stay outside the 965mm x 255mm rectangle.

3. Mark the board to a rectangle of 965mm x 255mm and shape the plate within these easurements.

4. Cut to shape, plane to an aerofoil section and fasten stops and handle.

 

 

Section E - Rudder Assembly

Swing Type - Material : 175mm x 20mm timber - 1.2M

1. Either purchase 6mm ply or for cheapness glue together two pieces of your scrap ply to make the rudder checks. The shape of these can vary within the required measurements on the plan.

2. Shape the spacer from the 20mm board and glue between the cheeks.

3. Shape the blade not more than 165mm wide and 730mm long (see class rules and plane to an aerofoil shape.

4. Fasten to the stock with a 6mm bolt and wing nut.

5. Shape the tiller handle from 45mm x 20mm material, glue and screw to stock.

6. Note restriction of rudder depth below keel line when fixing rudder assembly to transom.

 

N.B. Timber colours may be used to advantage in rudder and centre plate, using narrow strips or perhaps a strip of a different colour timber.

 

Dagger Type - If using dagger type rudder make to size shown on plans, but remembering to varnish inside of cheeks before assembly.

Section F - Mast and Boom - Solid

Material - 54mm x 27mm selected oregon or spruce 2/4M

50mm x 20mm selected oregon or spruce 2/2.4M

1. Either have the sail track and slot run by the local joiner’s shop or do it by hand with a plough plane, to within 550 mm from the bottom.

2. Mark mast taper from 610 mm above deck level and cut taper off, leave some waste for shaping.

3. Glue and cramp the mast/boom using a cramp per 300mm, be careful to straighten the material. Any bend or twists glued in will stay.

4. Plane to shape, working from square section to octagonal to round.

N.B. Be careful how you store a mast or boom, preferably slot down on a level surface or on a set of bars. Oregon and spruce twist easily.

5. Cut away the track at the base or make a keyhole for sail entry.

6. Lacquer as soon as possible, including the sail track.
