SIST EN ISO 12217-3:2013

Small craft - Stability and buoyancy assessment and categorization - Part 3: Boats of hull length less than 6 m (ISO 12217-3:2013)

This part of ISO 12217 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of craft vulnerable to swamping are also encompassed. The evaluation of stability and buoyancy properties using this part of ISO 12217 will enable the boat to be assigned to a design category (C or D) appropriate to its design and maximum load. This part of ISO 12217 is applicable to boats of hull length less than 6 m, whether propelled by human or mechanical power, except habitable sailing multihulls. Boats of hull length less than 6 m which are fitted with a full deck and quick-draining cockpit(s) complying with ISO 11812 may alternatively be assessed using ISO 12217-1 or ISO 12217-2 (for non-sailing and sailing boats, respectively), in which case higher design categories may be assigned. In relation to habitable multihulls, this part of ISO 12217 includes assessment of vulnerability to inversion, definition of viable means of escape and requirements for inverted flotation. This part of ISO 12217 excludes:
- inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to
specific clauses of ISO 12217;
- personal watercraft covered by ISO 13590 and other similar powered craft;
- aquatic toys;
- canoes and kayaks;
- gondolas and pedalos;
- sailing surfboards;
- surfboards, including powered surfboards;
-  hydrofoils, foil stabilized boats and hovercraft when not operating in the displacement mode; and
- submersibles.
- NOTE Displacement mode means that the boat is only supported by hydrostatic forces.
- It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which
- need to be separately considered if appropriate.

Kleine Wasserfahrzeuge - Stabilitäts- und Auftriebsbewertung und Kategorisierung - Teil 3: Boote unter 6 m Rumpflänge (ISO 12217-3:2013)

Dieser Teil von ISO 12217 legt Verfahren für die Beurteilung von Stabilität und Auftrieb des intakten (d. h.
unbeschädigten) Bootes zu fest. Ebenfalls sind darin die Auftriebseigenschaften solcher Boote mit erfasst, die
empfindlich gegen Vollschlagen sind.
Die Beurteilung der Stabilitäts- und Auftriebseigenschaften erlaubt es, dem Boot eine Auslegungskategorie (C
oder D) zuzuordnen, die seiner Auslegung und seiner maximalen Zuladung entspricht.
Dieser Teil von ISO 12217 ist auf Boote mit einer Rumpflänge bis zu 6 m anwendbar, die durch Muskelkraft
oder Motor angetrieben werden, außer für Mehrrumpfsegelboote mit Wohneinrichtung. Boote mit weniger als
6 m Rumpflänge, die voll gedeckt sind und schnell-lenzende Plicht(en) gemäß ISO 11812 besitzen, können
alternativ auch nach ISO 12217-1 oder ISO 12217-2 (für Nicht-Segelboote bzw. Segelboote) bewertet
werden, sodass ihnen gegebenenfalls eine höhere Auslegungskategorie zugewiesen werden kann.
Ausgeschlossen von der Anwendung dieses Teils von ISO 12217 sind:
- Wasserspielzeuge;
- Kanus, Kajaks oder andere Boote mit weniger als 1,1 m Breite;
- aufblasbare Boote und starre aufblasbare Boote nach ISO 6185, mit Ausnahme der Verweisungen, die
sich in jener Norm auf bestimmte Abschnitte von ISO 12217 beziehen;
- Wasserskooter entsprechend ISO 13590;
- Tragflügelboote und Luftkissenfahrzeuge, sofern sie im Zustand dynamischen Auftriebs fahren; und
- Tauchfahrzeuge.
Er enthält keine Angaben oder Beurteilungen zu den die Stabilität betreffenden Auswirkungen von
Abschleppen, Fischen, Ausbaggern oder Ausheben; diese sollten, falls erforderlich, gesondert berücksichtigt
werden.

Petits navires - Évaluation et catégorisation de la stabilité et de la flottabilité - Partie 3: Bateaux d'une longueur de coque inférieure à 6 m (ISO 12217-3:2013)

L'ISO 12217-3:2013 spécifie les méthodes d'évaluation de la stabilité et de la flottabilité des bateaux à l'état intact (c'est à dire non endommagés). Les caractéristiques de flottabilité des bateaux susceptibles d'envahissement sont également comprises.
L'évaluation des propriétés de stabilité et de flottabilité faite en utilisant l'ISO 12217-3:2013 permettra d'attribuer à un bateau une catégorie de conception (C ou D) appropriée à sa conception et sa charge maximale.
L'ISO 12217-3:2013 est applicable aux bateaux d'une longueur de coque inférieure à 6 m, propulsés par l'énergie humaine ou une énergie mécanique, à l'exception des voiliers multicoques habitables. Les bateaux d'une longueur de coque inférieure à 6 m qui sont entièrement pontés et dotés de cockpit(s) rapidement autovideur(s) conforme(s) à l'ISO 11812 peuvent alternativement, être évalués en utilisant l'ISO 12217‑1 ou l'ISO 12217‑2 (respectivement pour les bateaux à propulsion non vélique et les voiliers), dans quel cas il pourrait en résulter l'attribution d'une catégorie de conception supérieure.
Pour ce qui concerne les multicoques habitables, l'ISO 12217-3:2013 comprend l'évaluation de la vulnérabilité à l'inversion, la définition d'un moyen d'échappée viable et les exigences de flottabilité à l'état inversé.
L'ISO 12217-3:2013 exclut:

Mala plovila - Stabilnost in ocena vzgona ter kategorizacija - 3. del: Čolni s trupom, krajšim od 6 m (ISO 12217-3:2013)

Ta del standarda ISO 12217 določa metode za oceno stabilnosti in vzgona brezhibnih (nepoškodovanih) čolnov. Zajete so tudi značilnosti plovnosti plovila, ki je izpostavljeno zalivanju. Ocena značilnosti stabilnosti in vzgona z uporabo tega dela standarda ISO 12217 bo omogočila, da bo čoln vključen v konstrukcijsko kategorijo (C ali D), ki je ustrezna glede na konstrukcijo in največjo obremenitev. Ta del standarda ISO 12217 se uporablja za čolne s trupom, krajšim od 6 m, ki jih poganja človek ali stroj, z izjemo večtrupnih bivalnih jadrnic. Čolne s trupom, krajšim od 6 m, ki imajo neprekinjen krov in krmarjeve prostore s hitrim odvodnjavanjem v skladu s standardom ISO 11812, je mogoče oceniti tudi z uporabo standarda ISO 12217-1 ali ISO 12217-2 (čolni razen jadrnic in jadrnice), pri čemer se jim lahko dodeli višje konstrukcijske kategorije. V povezavi z večtrupnimi bivalnimi plovili ta del standarda ISO 12217 vključuje oceno izpostavljenosti prevrnitvi, navedbo ustreznih možnosti umika in zahteve za plovnost v prevrnjenem stanju. Ta del standarda ISO 12217 izključuje:
– napihljive čolne in napihljive čolne, ki imajo v spodnjem delu trupa togo enoto, ki jih obravnava standard ISO 6185, razen pri sklicih iz standarda ISO 6185 na določene točke standarda ISO 12217;
– osebna plovila, ki jih obravnava standard ISO 13590, in druga podobna plovila na pogon;
– vodne igrače;
– kanuje in kajake;
– gondole in čolne na pedala;
– jadralne deske;
– deske, vključno z deskami na motorni pogon;
– hidrogliserje, čolne s stabilizacijskimi flapi in plovila na zračno blazino, kadar ne delujejo v načinu izpodriva; ter
– plovila, ki lahko plujejo pod vodno gladino.
OPOMBA: Pri načinu izpodriva na čoln delujejo le hidrostatične sile.
Ne vključuje ali ne vrednoti vpliva na stabilnost pri vlečenju, ribolovu, črpanju ali dvigovanju, pri katerih je treba ustreznost stabilnosti obravnavati posamezno.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12217-3 was prepared by Technical Committee ISO/TC 188, Small craft.
This second edition cancels and replaces the first edition (ISO 12217-3:2002), which has been technically
revised. It also incorporates the Amendment ISO 12217-3:2002/Amd.1:2009.
ISO 12217 consists of the following parts, under the general title Small craft — Stability and buoyancy
assessment and categorization:
— Part 1: Non-sailing boats of hull length greater than or equal to 6 m
— Part 2: Sailing boats of hull length greater than or equal to 6 m
— Part 3: Boats of hull length less than 6 m

1 Scope
This part of ISO 12217 specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged)
boats. The flotation characteristics of craft vulnerable to swamping are also encompassed.
The evaluation of stability and buoyancy properties using this part of ISO 12217 will enable the boat to be
assigned to a design category (C or D) appropriate to its design and maximum load.
This part of ISO 12217 is applicable to boats of hull length less than 6 m, whether propelled by human or
mechanical power, except habitable sailing multihulls. Boats of hull length less than 6 m which are fitted
with a full deck and quick-draining cockpit(s) complying with ISO 11812 may alternatively be assessed using
ISO 12217-1 or ISO 12217-2 (for non-sailing and sailing boats, respectively), in which case higher design
categories may be assigned.
In relation to habitable multihulls, this part of ISO 12217 includes assessment of vulnerability to inversion,
definition of viable means of escape and requirements for inverted flotation.
This part of ISO 12217 excludes:
— inflatable and rigid-inflatable boats covered by ISO 6185, except for references made in ISO 6185 to
specific clauses of ISO 12217;
— personal watercraft covered by ISO 13590 and other similar powered craft;
— aquatic toys;
— canoes and kayaks;
— gondolas and pedalos;
— sailing surfboards;
— surfboards, including powered surfboards;
— hydrofoils, foil stabilized boats and hovercraft when not operating in the displacement mode; and
— submersibles.
NOTE Displacement mode means that the boat is only supported by hydrostatic forces.
It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which
need to be separately considered if appropriate.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
NOTE The meanings of certain symbols used in the definitions are given in Clause 4.
3.1 Primary
3.1.1
design category
description of the sea and wind conditions for which a boat is assessed to be suitable by this part of ISO 12217
NOTE See also 9.2.
3.1.2
recess
volume open to the air that might retain water within the range of loading conditions and corresponding trims
EXAMPLE Cockpits, wells, open volumes or areas bounded by bulwarks or coamings.
NOTE 1 Cabins, shelters or lockers provided with closures according to the requirements of ISO 12216 are not recesses.
NOTE 2 Cockpits that are open aft to the sea are considered to be recesses. Flush decks without bulwarks or coamings
are not recesses.

3.1.3
quick-draining recess
recess fulfilling all the requirements of ISO 11812 for “quick-draining cockpits and recesses”
NOTE 1 ISO 11812 contains requirements with which most sailing dinghies cannot comply.
NOTE 2 According to its characteristics, a cockpit may be considered to be quick-draining for one design category, but
not for a higher category.
3.1.4
watertight recess
recess fulfilling all the requirements of ISO 11812 for “watertight cockpits and recesses”
NOTE This term only implies requirements in respect of watertightness and sill heights, but not those for drainage.
3.1.5
fully enclosed boat
boat in which the horizontal projection of the sheerline area comprises any combination of:
— watertight deck and superstructure, and/or
— quick-draining recesses complying with ISO 11812, and/or
— watertight recesses complying with ISO 11812 with a combined volume of less than (L B F )/40, and
H H M
all closing appliances having their degree of watertightness in accordance with ISO 12216
NOTE The size of recesses permitted for some boats of design category C is restricted by the requirements of 6.4.
3.1.6
partially protected boat
boat which does not fulfil the definition of a fully-enclosed boat and in which the plan projected area of decking,
cabins, shelters, outboard engine wells or other rigid covers which are watertight from above according to
ISO 12216 and which immediately shed water directly overboard (i.e. not via drains) and
— comprises at least one-third of the plan projected area of the sheerline, and
— includes all the area within L /3 from the bow, and
H
— includes at least 100 mm inboard from the sheerline,
except that the area of any watertight recesses with a total volume of less than (L B F )/40 may shed
H H M
water via drains
NOTE 1 This is illustrated in Figure 1.
NOTE 2 Outboard engine wells are considered to provide a covering suitable for this purpose.

Key
1 recess area open from above (less than two-thirds of the total sheerline area)
2 sheerline
3 open shelter or enclosed cabin
Figure 1 — Partially protected boat
3.1.7
habitable boat
boat having a fully enclosed cabin with rigid roof fitted with one or more bunks, benches, pipecots, hammocks
or similar locations that can be used for sleeping when the boat is under way
NOTE 1 A boat is considered to be “habitable” if a fabric closure is used instead of a rigid door, or the cabin has fabric sides.
NOTE 2 The following are not considered to render a boat “habitable”:
— a cockpit tent, or
— an open-sided cuddy intended to provide limited protection from spray, provided it is not fitted with fabric closures all round.
NOTE 3 Locations used for sleeping have minimum dimensions of 1,5 m diagonal length, 0,4 m width at the widest
point, and with a minimum headroom of 0,4 m over the length. The cabin sole and compartments designated by the builder
to be used exclusively for storage and referenced in the owner’s manual are not included.
3.2 Downflooding
3.2.1
downflooding opening
any opening in the hull or deck (including the edge of a recess) that might admit water into the interior or bilge
of a boat, or a recess, apart from those excluded in 6.3.1.5
3.2.2
downflooding height
h
D
smallest height above the waterline to any downflooding opening (apart from those excluded in 6.2.1.5) when
the boat is upright in calm water in the maximum load condition, measured to the critical downflooding point
which might be within pipes or ducts inside the hull
NOTE Downflooding height is expressed in metres.

3.2.3
downflooding angle
φ
D
angle of heel at which the downflooding openings (apart from those excluded in 6.2.1.5) become immersed,
when the boat is in calm water and in the appropriate loading condition at design trim
NOTE 1 Downflooding angle may be determined using either of the methods in Annex B.
NOTE 2 Where openings are not symmetrical about the centreline of the boat, the case resulting in the smallest
angle is used.
NOTE 3 Downflooding angle is expressed in degrees.
3.3 Condition and mass
3.3.1
empty craft condition
empty boat including fittings and equipment as listed below but excluding all optional equipment and fittings not
included in the manufacturer’s basic outfit:
a) structure: comprising all the structural parts, including any fixed ballast keel and/or drop keel/centreboard/
daggerboard(s) and rudder(s);
b) ballast: any fixed ballast installed;
c) internal structure and accommodation: bulkheads and partitions, insulation, lining, built-in furniture, flotation
