SY Cassiopeia

Cassiopeia was built in 1939 to carry marble. Since the 1960s, she has been operated as a private yacht.




Responsible Voyaging

Under new ownership since July 2025, the next chapter in Cassiopeia's story is to sympathetically reduce our impact on the environment we are so privileged and lucky to witness at first hand on our voyages.

Our fundamental aim is to reduce our dependence on fossil fuels, to increase awareness of the preciousness of the life-sustaining natural resources we consume as we journey, to understand and mitigate the potential harms and consequences of our actions and to set an example of how recreation at sea can also educate, inform and be environmentally responsible whilst still being rewarding and fun. This website will track our progress towards achieving those ambitions.
