The Port of London Authority (PLA) organised an event to celebrate the start of Pride month alongside several other organisations including the RNLI, Thames Skills Academy and Transport for London.
Representatives and supporters of the tidal Thames' LGBT+ community gathered on the river at Waterloo Bridge. The event was hosted by Woods Quay, the new home of Woods' Silver Fleet.
Debbie Cavaldoro, Head of Strategy and Policy attended the event on behalf of Nautilus.
Robin Mortimer, PLA chief executive, said: 'As Pride month gets under way, it's important to celebrate the LGBT+ community and ensure we continuously promote acceptance.'
The gathering coincides with the easing of covid restrictions and the return of tourist and commuter passenger boat operations on the river.
