Sydney’s premier IYT sailing school


Learn to sail in Sydney starts with AusSea Sailing School, Sydney’s premier IYT sailing school. AusSea Sailing School was started by Marc van Dinther in 2009. Marc remains the driving force behind the sailing school and with his patient and fun way of teaching he has introduced thousands of people to his favourite sport. He’s very serious about delivering quality sailing lessons, so much so he moved the school from busy, choppy Sydney Harbour to Botany Bay. This stretch of water, close to Sydney, Cronulla and Wollongong, is over two times the size of Sydney Harbour and a much better place to learn how to sail keelboats safely and confidently.

AusSea Sailing School is a proud partner of International Yacht Training Worldwide (IYT), the global leader in sail training. This means that your sailing qualification is global, very useful if you are looking at chartering a yacht in the Mediterranean and the Pacific, where an International Certificate of Competency (ICC) is a requirement.

Apart from the extensive ICC program we offer a wide range of courses to suit everyone’s needs and budgets, from beginners’ and bareboat skipper courses to spinnaker and offshore training. For our inshore courses we sail on J24’s on Kogarah Bay and Botany Bay. During our offshore courses (Coastal Skipper, ICC and bareboat skipper courses) our ocean yacht Renegade (S111) takes students out on the Tasman Sea, Port Hacking, Pittwater, Sydney Harbour and the Whitsundays.




The Inshore Skipper Courses, all four lessons of three hours, lay a solid foundation for the rest of your sailing life.

Our  Try Sail is a fantastic way to get a taste for sailing if you’re not 100% sure yet. Come and join us for a fun and safe two hour sail on Botany Bay. 

The Introduction Course (Level 1)  (4 lessons of 2 hours) consists of 8 hours of sailing, a start sailing pack with our bestseller Sail Like A PRO, a logbook, dri-fit sailing cap and other things to get you started. On completion you’ll have good boat handling skills, know the road rules and you’ll be able to sail a figure of eight.

After the Intermediate Course (Level 2) (4 lessons of 2 hours) you’ll be  aware of hazards and know how to avoid them, you can retrieve a person overboard safely, can pick up moorings under sail and can shorten sails whilst underway.

The Advanced Course (Level 3) (4 lessons of 2 hours) will finalise the Inshore Skipper pathway. You’ll know how to sail your keelboat safely on and off the mooring and jetty, you can handle a boat in the confined spaces of Sylvania Waters, can pole out and gybe a head sail and can steer a yacht without a rudder by using the sails.


During our Offshore Courses you’ll learn how to skipper a big yacht on the ocean.

Our Coastal Skipper Course (Level 4) is a full day course. We sail Renegade, a S111, from Sans Souci to Sydney Harbour and back. Aside from testing your sea legs, this will be a great way to practice coastal navigation, learn about safety offshore, how to work as an efficient crew and experience night sailing.

The International Bareboat Skipper Course (Level 5) finalises the ICC pathway. This is a two day overnight course on Renegade, either on Sydney Harbour or Port Hacking. After obtaining VHF Marine Radio certificate and ICC, you’ll be able to charter yachts up to 24 meters around the world. 

It’s also possible to sit just the ICC practical and theory exam, after demonstrating prior experience. If you identify areas you feel weak in, we are happy to discuss a pathway to bring you up to speed.


Our Racing Course is THE best one in Australia, simply because we don’t only teach you the ins and outs of racing, but you’ll also be able to put it all into practice during a real spinnaker race.

During one full day you’ll learn how to pack, hoist, gybe and douse a spinnaker and you’ll experience the different positions on a racing yacht. This course is exhilarating and one of our quick sell outs, so don’t hesitate and book your spot.

On completion you’ll be totally race ready and through our crew and yacht register, we’ll help you to find a suitable yacht to crew on, whether it be on Botany Bay, Port Hacking, Sydney Harbour or Wollongong.

The Coastal Skipper pathway consists of Level 1-3 and our Coastal Skipper Course (Level 4) and will set you up if you’re planning to sail a yacht on the Eastcoast.

This overnight course onboard Renegade, our S111, completes the ICC pathway. During this weekend course on Port Hacking or Sydney Harbour you’ll eat, drink, breath and sleep sailing.

Racing Crew


This course is for speed demons and cruisers alike, as spinnakers are an essential tool for passage making. During this full day course we’ll teach you how to pack, hoist, trim, gybe and drop a spinnaker while experienceing the different crew positions. At the end of the day we’ll join a spinnaker race to put everything into practice. A free listing on our crew register is also part of this course.
