Class Measurement

Joel Gaté - official measurer of the Classe Mini
Joel Gaté - official measurer of the Classe Mini
Inspection meetings will be scheduled during the racing campaign. It is incumbent upon each skipper to ask the Classe Mini for the dates of the inspection meetings and take appointment for one of them.

All non-measured boats or already measured but modified on any control point or effecting the measurements especially boats (prototypes and production boats) equipped with lithium batteries must be inspected at one of these meetings.

To participate in an official event published in the calendar, every boat must present a valid measurement form.

The cost of measurement is € 100 for a boat the Classe Mini has never checked and € 60 for boats already measured but with a modification which requires a new measurement.

A € 10 penalty payment will be applied for each nonconformity point that need to be re-checked.

The presence of the skipper and a crewmember is required to assist the measurer.

It is the skipper's responsibility to ensure that his boat remains completely in conformity with the last valid configuration of jauge. Sanctions will be taken if she doesn't.

PRESENTATION TO A MEASUREMENT SESSION

The skipper must take an appointment to the Classe Mini before the measurement session. He must be present at the appointment place and hour decided with the Classe Mini. As it is difficult to schedule the measurement sessions, the calendar really has to be respected.

Registration to a session will be valid once paid. An unjustified absence will result in the loss of the payment.

The boat must be empty except for the batteries and the liferaft, without fenders, halyards attached to the deck collar, spars in position. The daggerboards must be in high position.

The rigging must be tighten enough to allow the stability test in good condition. If he doubts, the measurer can ask for a new setting or refuse to make this stability test. In that case, the skipper will have to present the boat to another session at his expenses.

Physical stops or straps that limit the movements of mobile appendages must be in position so that their sealing can be applied right after the end of the stability tests.

What has to be shown:

Documents:

- the form showing the distribution of the flotation volume,

- the ship's license or equivalent,

- for the boats with a canting keel and/or mast, a written certificate from the designer detailing the worst configurations of the keel, the mast (specifying the positions) and of the ballasts for the large and small angles stability tests. Nevertheless, the measurer may ask, if he finds necessary, to check any other configuration. In the event one does not present this document or presents wrong datas, the setting of the real limiting positions during the measurement session will result in a € 50 penalty coming to be added to the cost of the measurement session.

The boat must be rigged and ready to sail with:

On the deck
- the definitive version of the mast and its rig, completed with its equipments,
- waterproof partner,
- the low part of the mast must be watertight internally if the mast goes through the deck,
- air pipes of the ballasts and their closing cap in position and fastened,
- the identification number of the boat on the deck and on the hull,
- the hatch boards for the companionway with the locking system that can be operated from inside and outside of the boat,
- lifelines in position,
- mainsail sheet in position.

Inside the boat

The skipper must ensure that there is no more water in the bilges and that all the personal or safety equipment is no more aboard except the following elements.

The following elements must be in position for the tests:

- the crash box bulkhead with inspection hatch if there is,
- the flotation reserves in position and fixed definitively,
- the ballasts in their final version with the pump and the equipment to bail, fill, isolate, empty or transfer,
- the drying equipment with two fixed pumps, one operable outside, the other operable inside, with the pipes,
- batteries fixed in their position,
- the protection of all through-deck bolts,
- electrical and electronic networks in position.

The Liferaft

According to the installation, the liferaft must be:

- fastened in its final position inside the boat, at 15 cm maximum from the transom, letting the safety hatch handles accessible,
- fastened in its final position outside the boat, on the border of the transom,
- the strap which inflates the liferaft must be fastened properly on the boat.

Once the visual checks and the measures are over, the measurer will proceed to the stability tests, with at the maximum air draft point a 45 kg + 3 kg weight (including the Archimede's effect).

As the test is stressing for the rigging, it is the skipper responsibility to chose which halyard to use to make this test. Either a mast head halyard or a fractional one.

Mini Rules - 2010 edition

The Mini Rules are designed to encourage offshore racing on small, moderately-priced monohull racing boats with short-handed crews.
The rules are intended to promote the research and development of security and performance of these sailboats in offshore racing.
Their function is also to help to develop seamanship, a sense of responsibility for the crews, and to promote sportsmanship and solidarity between competitors.

APPLICATION OF THE RULES
These rules are applicable from January 1st of the year, to all the Mini boats. The Administration Council of Classe Mini has full and exclusive authority to modify and interpret the rules. The official measurer is responsible for the application of the rules and can insist on a demonstration if necessary.
The French version of the text shall prevail.

The ongoing ISAF rules (ERS and OSR categories 1 to 5) apply. These rules are changed as follow:
- 3.02.2, 3.02.3: "daggerboard (and keel) boxes" does not apply, is replaced with the obligation of having a resistant cover perfectly waterproof in all points.
- 3.03: is replaced with article R-2
- 3.08.1: is replaced with the article J-8-c-3 of the Guide Mini.
- 3.08.3: "companionway" does not apply, is replaced with the application of, at least, the standard ISO 11812, article 8.2.2, table 5, category of conception B, “semi-fixed coaming” and article 8.2.4., the companionway hatch being the “mobil part”. For the application, see article J-8-c.
- 4.01.2: "Sail letters and numbers" changed, see article J-17 of the Guide Mini.
- 4.26.4.f: does not apply.

S-5-c Boats must be identical in regards to their components’ specifications and scantlings.

S-5-d The geometry of the various parts of the boat must be strictly the same (except the sails).

S-5-e Concerning the standing rigging, the boom, the spinnaker pole, the bowsprit and the mast, boats must be in accordance with the nomenclature or the measurement book the project manager provided.

S-5-f The project manager: architect and/or shipyard and/or class association must define a one-design rule for the following points :
- hull, deck and structure,
- appendices,
- sails,
- standing rigging,
- interior accomodations,
- deck hardware and design,
- authorized system(s) for spinnaker pole or bowsprit.
The one-design rule will help the project manager to settle the measurement book and will complete the actual

S-5-g A ratification file must be sent to the Classe Mini, which is the only one entitled to let a new boat race according to the ongoing Production Boat Mini Rules. This file has to be sent when asking for the first sails number to the Classe Mini.

S-5-h The boat will be declared production boat once :
- the ratification file specified in S-5 is sent to the Classe Mini and the Measurement Committee proposes the file to the Administrators' council that validates the boat,
- the project manager has built 10 strictly identical boats,
- the Classe Mini and the "jaugeur" have visited the shipyard (at the shipyard's expense) in order to check up the conformity of the building methods, this visit has to occur as the first boats are built (before the third one),
- the same boat has sailed without major incident :
- 2000 NM in races of the Mini program with at least two 500 NM legs non stop,
- one of the 1000 NM single handed qualifying courses specified in the article R-7-c, non-stop.
If the shipyard offers the B system option for bowsprit, these qualifications must be done by a boat with this system.

S-6 - DOCUMENTS

S-6-a For the first boat:
- identification number for the boat,
- attestation that the boat respects the European Rules regarding the stability, the freeboard and the buoyancy,
- typical rule for leisure production boat (customs),
- design :
- sails plan,
- rigging(s)' plan and nomenclature,
- deck plan,
- inside fittings plan,
- hull and deck structure plan,
- nomenclature of the material for the rudders,
- keel plan,
- plan for each bowsprit or spinnaker pole system the shipyard offers,
- measure book,
- one-design rule,
- moulds, necessary tools and calculation methodology that the measurers can use to eventually check points characteristic of the production boat's mini rules.

S-6-b For every one of the nine following boats:
- copy of the certificates of respect of the rule for leisure production boats,
- hull number,
- bowsprit and spinnaker pole system.
