OSR Structural Plan Review

Introduction and Aims

The aim of the World Sailing Offshore Special Regulations Structural Plan Review Scheme is to implement compliance with the requirements of World Sailing Offshore Special Regulations 3.03 - Hull Construction Standards (Scantlings).

The objective of the scheme is for World Sailing together with World Sailing recognized notified bodies to provide certification to designers, builders and/or owners to show compliance with specific parts of the International Standard ISO 12215: Hull Construction -Scantlings specified within the scope below.

Guidance and Procedure flow diagrams for Owners, Designers and/or Builders and Notified Bodies can be seen in the documents list below.

Plan Review

The structural plan review will be undertaken by World Sailing recognised notified bodies. These are organizations that are able to carry out assessments and issue CE certificates for the European Recreational Craft Directive and have also been recognized by World Sailing . World Sailing recognition is given to notified bodies that have demonstrated experience with ballasted sailing yachts, operate an ISO recognized quality management system and also undergo regular auditing by their national accreditation body. The list of notified bodies with contact information can be seen in the documents list below.


The scope of the plan review consists of application and calculation to the following parts of ISO12215 - Small Craft - Hull construction and scantlings:

ISO 12215 Part 5: Design pressures for monohulls, design stresses, scantlings determination
All parts and annexes where applicable to design category A ("ocean") - Sailing Craft
ISO 12215 Part 8: Rudders
All parts and annexes where applicable to design category A ("ocean") - Sailing Craft
ISO 12215 Part 9: Sailing Craft - Appendages
All parts and annexes where applicable to design category A ("ocean")


a) The boat shall show complete compliance with the above ISO standard parts.

b) In all applicable cases the ISO standards should be applied as the minimum.

c) Any interpretation of the ISO standard shall be as confirmed by World Sailing.

d) The latest version of the ISO standard shall be used at all times.

e) There is no building inspection or site visits. The review is plan based only.


There are two forms of certification:

a) Series production; where several boats of the same type are produced in accordance with the plans and therefore each yacht will not require individual review and certification

b) Custom or unique boat where the boat is a one of a kind yacht or a series production yacht that has been built or modified such that it is not in accordance with the plans of that series.

World Sailing will maintain a list of yachts reviewed under the scheme on its website with certification information. If the yacht is a series type production there will be a single entry for that type of yacht with a link to a certificate for an owner or builder to make a hardcopy. The owner then signs the declaration including the CIN/HIN of their particular yacht. For a unique yacht the certificate will not be published on the website and certificates will be issued direct from the World Sailing recognized notified body upon compliance with the review requirements.

The recognized notified body should return digital copies of series production certificates to World Sailing but are free to give them to individual owners on their request. Unique or custom certificates should be returned to the original enquiry source or their nominated individual.
