Amendments to version 1.0


Applicability in the Event

The recommendations below do not substitute, but supplement the requirements of governmental authorities and therefore constitute (often additional) recognised best practices. Each boat should try to adhere as closely as possible to the recommendations set out below treating them as far as possible as requirements and then present to the organisers a written document detailing each point of non-compliance with a reasoned explanation as to why they cannot meet the recommendation. Final acceptance of an entry in the event is subject to either the recommendations having been implemented in full or each non-compliance having been explained and responsibility taken for any non-compliance by the person in charge. The implementation of these recommendations do not guarantee total safety of the boat and her crew.

Event regulations


The highest authority in supplying best practices for safety at sea is World Sailing through the issuance of their Offshore Special Regulations.

For this reason, compiling a list of additional recommendations for boats participating in the Global Solo Challenge would have been impossible without referring to the cornerstone reference work done by World Sailing. The text below is therefore heavily inspired by the Offshore Special Regulations Monohull Category Zero, but has been reviewed and simplified. We still consider it due and necessary to recognise full copyright © ORC Ltd. 2002, amendments 2003-2020 © World Sailing Limited, but please refer to for further information and for all original text.

1 – Responsibility of Person in Charge

1.01 – The responsibility for a boat’s decision to participate in the Global Solo Challenge or continue in the event is hers alone. The safety of a boat and her only crew is the sole and inescapable responsibility of the Person in Charge who shall do his/her best to ensure that the boat is fully found, thoroughly seaworthy and that he/she is experienced and appropriately trained and physically fit to take part in the event.

1.02 – Application of these recommendations or inspection of a boat by the organisers does not in any way limit or reduce the complete and unlimited responsibility of the Person in Charge.
