Cannon Sloop Diana sailings

More than 200 years ago Viapori’s archipelago fleet, which participated in the large sea battle at Ruotsinsalmi, sailed Suomenlinna’s waters. Next summer, you can step aboard cannon sloop Diana, which has been built according to its 1700s role models, and sail the coastal waters of Suomenlinna.

Please note

Diana is an open boat, so dressing according to weather conditions is important. Due to the wind, it may be cold at sea even on a warm day. It is good to have a warm and relaxed casual outfit, as well as flat shoes, with you. In case of rain, it is good to bring a raincoat. It is also worth taking a bottle of water with you. Children can participate only with an adult.
