In a special report which looked into what happened in Langkwai, World Sailing confirmed Israeli allegations that their flag, logos and national anthem were banned by organisers in the host country.

It has also been revealed that the country's delegation were only told of the crackdown on December 16, just 11 days before the Championships' official arrival day on December 27.

Israel, who informed the Malaysians who was in their party ten-and-a-half weeks before the competition, were further told that their participation would be limited to "the formal part of the event" but World Sailing has blasted the situation as "unacceptable".

Situations such as this have occurred in Israeli sport before, usually involving Muslim nations which do not recognise the country.

In November, the Israel flag was banned from the International Judo Federation Grand Slam event in the United Arab Emirates capital Abu Dhabi, but World Sailing is keen to avoid a repeat situation in its competitions.

This appears, however, to mean that countries being blocked must raise any potential problems in good time.

"Countries who do not have diplomatic relations with the country of a chosen venue, and officials who know they may have difficulty over entry into a country, shall accept the need to highlight these challenges well in advance," their report read.

"Such countries shall be prepared to select sailors and plan participation early enough for arrangements to be made.

"Known areas of difficulty shall be taken into account when evaluating venues.

"The chosen venue shall identify any areas of risk, and agree with World Sailing the schedule for progressing them.

"This schedule needs to recognise that some elements are outside the host venue or member National Association's control, and shall be designed to ensure that any identification of problems or discussion of conditions is early enough to enable a resolution to be agreed in good time."

Israel were due to send windsurfers Yoav Omer and Noy Drihan to Malaysia and Israel Sailing Association chairman Gili Amir has not ruled out legal action against World Sailing.

The report says that Malaysian authorities breached article seven of the World Sailing constitution, which states that a host must "ensure that there shall be no discrimination on the grounds of race, religion or political affiliation against any competitor representing a Member National Authority."

The short notice given by both countries was also criticised, with the governing body stating that "the late starting of the process to enable Israeli sailors to participate, delays and poor communication by all parties during that process, and the late notification of the conditions, contributed to the outcome and made it impossible for World Sailing and the International Olympic Committee to resolve the incident before the championships."

World Sailing has now written to authorities in Israel and Malaysia about what happened.

"There is no place for discrimination of any kind in the worldwide sport of sailing and an obligation of membership of World Sailing is to act without discrimination," the report states.

"When selecting future venues, World Sailing shall require explicit acceptance at the bid stage and in the contract of sailing's "no discrimination" requirement as it applies to that regatta."

An early tester of the rules could be the next Youth Sailing World Championships, which are due to take place in Oman, another Islamic country, in December 2016 and January 2017.

Israel itself will host the edition after that, in Akko in July 2017.

Any country which breaches the rules could see itself excluded from selection as a future venue or could even have its World Sailing membership cancelled.
