It is easier for children to learn on small boats and work their way up to larger boats as they grow. Children learn better in a protected harbor or cove because there is less wind than the wide open ocean. The Wayfarer was the standard teaching boats for adult schemes; however, many centres have moved onto more modern 'Centre-Main' boats such as the Laser Stratos and Topaz Omega. In Australia the main boats children learn in are Sabot (dinghy), Manly Junior, Heron, Topaz Dinghy, Flying Eleven, Optimist with the O'pen BIC becoming more popular. Adults often learn in Spirals or Sabres or by crewing in NS14s or Tasars.
