Link to Section 2: Instructions for Measuring the MG14 Dinghy

Section 1:
INTENTION OF THE CLASS MEASUREMENTS AND RESTRICTIONS
The class rules are designed to provide monohull boats that will yield high performance with varying crew weights, varying hull and rig designs and varying ages of crews and boats. The boats shall not be so restricted as one design but not have unlimited development. The MG14 & MG14B should be a light weight exciting sailing dinghy with the added challenge of a spinnaker and trapeze, with sail area easily handled by two persons both in the water and out, with no minimum or maximum crew weight. The Association should be made aware of unusual hull or rig designs, and it shall make a ruling in the interests of the Association and its Members, keeping in mind this intention.

 

1. HULL
Hulls may be constructed of any material provided that they are safe and durable. Any design may be used with the exception of scows and catamaran type hulls which are not permitted. New hull designs shall be measured and ruled on by an Association Measurement Sub-Committee, consisting of the President, the Association Measurer and one other member of the Association Committee.

 

2.LENGTH
The overall length as measured between perpendiculars, not including rudder pintles, or a fixed or retractable spinnaker pole or its supports, fore and aft with the waterline horizontal, shall not exceed 4.30m nor be less than 4.25m. Rudder extensions are not allowed. To prevent their being fitted any rudder fitting fixed to the boat and extending more than 50mm aft of the normal aft length measurement is to be included in the length.

 

3. MINIMUM BEAM
T
he beam when measured at the widest part shall be not less than 1.60m. Furthermore the beam measured 2.5m from the fore perpendicular and 200mm above the outside of the keel, or outer skin on mid beam line if there be no keel, with the boat on an even keel shall be not less than 1.22m.

4. MAXIMUM BEAM
The hull and all fittings shall pass between perpendiculars 1.83m apart with the hull on an even keel.

 

5. DEPTH
The depth, 2.5m from the fore perpendicular measured between the bottom of the keel or keel band and the highest point of the gunwale or deck within 50mm of the maximum beam at the 2.5m station shall be not less than 450mm. Furthermore, the hull when upright, excluding fittings and the mast step and pin, shall pass between two horizontal lines vertically spaced by 660mm.

 

6. PROJECTIONS
A taut tape containing any vertical cross section of the hull including the gunwale assembly and keel shall not pass at a greater distance from the nearest point of the skin than 60mm when measured at right angles to the taut tape.

Bowsprits are not permitted.

Any fitting or device attached to the hull and protruding in the horizontal direction beyond the normal extremities of the hull, with the exception of a fixed or retractable spinnaker pole and its supports, is to be of such material that in case of impact it will bend or collapse so as not to cause damage or injury to another boat or crew.
 

7. DEVICES FOR LEVERAGE
The use of any device outside the outer surface of the skin of the hull to obtain leverage by the means of the projection of the weight of any one or more of the crew is not allowed. A trapeze may be used provided that such trapeze consists of a wire or rope attached to the mast or rigging and may be used by not more than one member of the crew at one time. The lower end of the wire or rope must be securely fixed to the boat or standing rigging when not in use.

 

8. COCKPITS AND BUOYANCY
A minimum of approximately 0.45 cubic metres of buoyancy shall be provided, so disposed that a boat can be righted and sailed on under control while being bailed out after a capsize. The disposition of the buoyancy shall be to the satisfaction of the measurer, who in case of doubt may require the ability to right and sail on to be demonstrated in heavy weather. The hull, complete with rudder and centreboard but without the rig, shall provide buoyancy of 20kg minimum so distributed that the boat will float upright with all buoyancy compartments flooded.

 

9. MINIMUM WEIGHT
The minimum weight of the dry hull with permanent fittings attached, but without spars, centreboard, rudder, sails, mainsheet, jib sheet, spinnaker sheet, vang, rigging and anything removable, shall be 64 kilograms. Any ballast necessary shall be permanently fixed not less than 300 mm above the keel. This ballast may be reduced if subsequent re-measurement shows the weight has increased (e.g. addition of fittings).

 

10. CENTREBOARDS AND RUDDERS
There shall be no restrictions as to the size, shape or thickness except that there shall be no increase in thickness below the keel. The centreboard and rudder blade are to be secured in such a way that in the event of a capsize they remain entered in their respective cases. The tiller shall be fixed to the rudder and the rudder fixed to the hull in such a way that neither can become unshipped during a capsize.

 

11. SPARS
All spars, excluding fittings, shall pass through a 100 mm internal diameter ring.

The mast shall;

[a] Float; or

[b] Have drain holes within 300 mm of the base of the mast capable of emptying a mast full of water within one minute.

The mast may not extend more than 5.65m above the highest point of the foredeck. For MG14 only, if the mast extends more than 5.50m above the deck, the portion between 5.50m and 5.52m shall be painted black or a contrasting colour. Where the boat has no foredeck then the maximum mast height above the bottom of the keel shall be 6.31m, and for MG14 only, the band shall be painted between 6.16m and 6.18m above the bottom of the keel. For MG14, no sail or portion of any sail shall be hoisted above the bottom of the painted band. For MG14B, no sail or portion of any sail shall be hoisted above the top of the mast.

For MG14, the spinnaker halyard exit point shall be a minimum of 800 mm below the bottom of the painted band. For MG14B, the spinnaker halyard exit point shall a maximum of 5.1m above the fore deck or 5.76m above the keel.

A fixed or retractable spinnaker pole for an asymmetric spinnaker shall not extend more than 1.40m from the bow of the hull.

12. SAILS
Each boat shall submit for measurement all sails intended for use in class racing. The Association or Club Measurer may measure the sails again at any time at his discretion.

Sails shall be measured in accordance with the instructions laid down in section 2 "Instructions for Measuring the MG 14 & MG14B Dinghy". The Association or Club Measurer shall sign each sail measured and shall mark thereon the sail area or perimeter measurement and the date of measurement.

The Measurer shall re-measure any sails altered after measurement.

Any set of sails that have been measured and then altered, without being re-measured, signed and marked by an official measurer will disqualify the boat concerned from competing in races conducted by Clubs or the Association.

For MG14
Sails shall consist of mainsail, jib and spinnaker. The combined area of the mainsail and jib, after rounding the areas of each sail to the nearest 0.1 square metre, shall not exceed 9.3 square metres. The area of the jib, after rounding to the nearest 0.1 square metre, shall be not less than 1.4 square metres. The area of a double luff spinnaker, after rounding to the nearest 0.1 square metre, shall not exceed 7.5 square metres. The perimeter measurement of an asymmetric spinnaker shall not exceed 14 metres.

For MG14B Sails shall consist of mainsail, jib and spinnaker. The combined area of the mainsail and jib, after rounding the areas of each sail to the nearest 0.1 square metre, shall not exceed 10.5 square metres. The area of the jib, after rounding to the nearest 0.1 square metre, shall be not less than 1.4 square metres. The perimeter measurement of an asymmetric spinnaker shall not exceed 15.4 metres.

13. LIMITATIONS
(a) During an MG 14 Association State or National Title Series held over a maximum period of three consecutive weeks, each boat may use not more than;
One (1) Mainsail  Two (2) Jibs
One (1) Spinnaker  One (1) Mast
One (1) Boom  One (1) Spinnaker Pole
One (1) Centreboard  One (1) Rudder

(b) Items used or to be used in a Title Series may be inspected by the Association Measurer or Race Committee at the time of entry to the series or at any time during the series.

(c) No changes shall be allowed during a State or National Title series which is held over a maximum period of three consecutive weeks, except in cases where gear is damaged accidentally or in use and is beyond repair or unable to be repaired at that event. Details of the damaged items and of the circumstances under which the damage occurred shall be submitted in writing to the Association Measurer along with the items for inspection. Replacements through damage will be accepted at the discretion of the Association Measurer, and shall not be made without the written approval of the Association Measurer.

(d) No alterations are permitted to sails once they have been registered and accepted for a State or National Title. The only exceptions are for repairs or if sails are found to be oversize.

In such circumstances, sails are to be presented to the Association Measurer prior to and after any alteration. Sails must be re-measured after alteration, except in the case of minor repairs when the Association Measurer may at his or her discretion rule that re-measurement is not required.

The Association Measurer must inform the Race Committee of any attempt to improve or alter the shape or performance of a sail. If the Committee finds evidence of this, the sail shall be ruled ineligible and returned to its original shape as registered, with any necessary reduction in size, or be disqualified.

14. HALYARDS
A halyard locking system or mainsail release device must be fitted to enable the mainsail to be lowered while the yacht is either upright or capsized.

 

15. CREW
The crew is to be made up of no less than two (2) persons. It is intended that the practice of seeking advantage by changing crews to suit the weather should be discouraged.

 

16. REGISTERED NUMBER

The MG14 and MG14B shall share the same sequence of registered numbers, and a boat shall be issued with a single registration number, irrespective of registration as an MG14 and/or as an MG14B.

The Class Measurement Plate shall be fastened in a conspicuous position in the forward end of the cockpit. The design of the plate shall be as illustrated below:


17. CLASS INSIGNIA
