Sailing Vessel

Denis Sullivan

2020 Season Cancelled: 

It is with a heavy heart we announce that the S/V Denis Sullivan will not be sailing nor open to the public for the 2020 season.

This season we were hoping to celebrate the 20th Anniversary of the launching of the S/V Denis Sullivan, as well as our own Captain Tiffany Krihwan receiving the prestigious ‘Sail Trainer of the Year’ award from Tall Ships America. Instead, the ship will be remaining docked with the bare minimum of crew continuing maintenance work as long as possible. One of the worst things for a wooden vessel is to be neglected. Therefore, we need your help! Please consider donating to the S/V Denis Sullivan to help us continue caring for the ship. It doesn’t matter if the ship is docked or if it sails all 5 Great Lakes in a season, the minimum yearly cost to maintain the S/V Denis Sullivan is about $300,000.

Thank you for understanding during this difficult time. We hope to see all of you back out sailing on the Great Lakes in 2021!

Help Support the Sullivan

Discovery World is proud to be the home of the S/V Denis Sullivan, our resident tall ship used for educational experiences at Discovery World. The programs held on the Sullivan enhance out-of-school, hands-on learning while empowering youth to explore, innovate and create. Additionally, Discovery World is proud to be gaining regional prominence as an attraction for residential quality of life and tourism, while simultaneously providing opportunities to connect the innovation industries of Milwaukee and Wisconsin to the marketplace because of our maritime programming. Water is the world’s most precious resource, and the S/V Denis Sullivan provides a unique platform from which to provide marine education, leadership training, and personal development to visitors of all ages. The Sullivan needs your support, as it costs approximately $300,000 annually to operate and does not attain that amount in revenue from programming. Supporters like you allow Discovery World to make it possible for us to inspire Milwaukee’s next generation of innovators and entrepreneurs, and we are grateful for the opportunity to partner with you on their behalf.

Educational Program & Charter Info

For information regarding all of our educational programs we offer for schools and groups, including those onboard the S/V Denis Sullivan, please click here to view our Education pages.

Professional development charters aboard the S/V Denis Sullivan challenge teachers to live and work aboard the traditionally rigged schooner. Educators on the S/V Denis Sullivan specialize in getting teachers out of the classroom and inspiring them to share these experiences with their students.

A charter on the S/V Denis Sullivan will give you a new passion and excitement for teaching, experiential education training, and a wealth of knowledge to take back to your classroom.

The S/V Denis Sullivan is modeled on a traditional vessel, but is equipped with the technology for a hands-on study of ecological systems. Journey the open waters of the Great Lakes for three hours or seven days.

A private, 2-hour charter sail on the S/V Denis Sullivan offers an environment that no other venue can match.

As a captivating and impressive platform to network, express gratitude, celebrate or simply socialize, the experience offers a peaceful setting on Lake Michigan and a quiet sail on the world’s only traditional Great Lakes schooner.

While aboard, you and your guests will be able to participate in raising sail, take a turn at the helm, tack through the wind, learn something new, or simply relax, unwind and sail! Take your people into an environment surrounded by water, where the benefits of working together truly sail you home to safety. Charters are a great option for team-building events, employee appreciation events, weddings, vow renewals, anniversaries, and other special occasions.

There is a 50 person maximum limit per charter. Any bartender, caterer, or other vendor on-board would count toward this 50 person limit.

2-Hour Charters begin at $3,000. Additional fees apply for Beer and Wine Options.

History & Ship Info

The S/V Denis Sullivan was completed in Milwaukee, Wisconsin in 2000 by professional shipwrights and nearly 400 volunteers. The schooner is a modern educational sailing vessel with two diesel engines, a scientific laboratory, two computer workstations, and modern communication and navigation equipment. She maintains single bunks in co-ed areas, shared toilets (heads) and showers, and limited storage. The vessel can carry up to 50 passengers on day sails and 20 participants overnight. She is complemented by a professional crew of 10.

The S/V Denis Sullivan provides an array of genuine maritime experiences, from two-hour Lake Watches for families to multi-day educational sails for teens and adults. Water is the world’s most precious resource, and the S/V Denis Sullivan provides a unique platform from which to provide marine education, leadership training, and personal development to visitors of all ages.
