Sailors' Society chair of trustees Peter Swift said: 'We are delighted to have secured such a strong candidate to take over and build on Sailors' Society's work providing a lifeline for seafarers and their families around the world.
'Our new CEO joins us as at a time of great innovation, as we offer new virtual services to complement our traditional roles, including our industry-leading Wellness at Sea programme and our family outreach.
Ms Baade said: 'Sailors' Society is a charity that not only delivers a real positive difference to seafarers, but also to the wider seafaring community and I couldn’t be more honoured and excited to join and lead the charity going forwards.'
