Unlike other recreational yachting organisations such as the Royal Yachting Association (RYA), Yachting Australia (YA), the American Sailing Association (ASA) or International Sailing School Association (ISSA), IYT is a professional yachting organisation that is run by professional mariners for professional and recreational mariners and we issue professional yachting certificates (where applicable). No other organisation offers training on a global scale with more courses in more countries, in more languages through more schools and with more Government approvals than IYT.
