The MMO said its event would help people understand solitary dolphin behaviour, the dangers of human contact and how they could help protect the wild visitor.
One of the speakers, Liz Sandeman from Marine Connection, leads its solitary, sociable dolphin project.
She said: “When lone dolphins start spending time closer to shore, unquestionably their behaviour does change within months.
“They quickly become accustomed to humans and boats, losing their instinctive fear and caution, which could potentially put them at greater risk.
“Solitary, sociable dolphins represent a unique behavioural group that requires focused conservation efforts and this individual dolphin needs protection now more than ever.”
A speaker from Whale and Dolphin Conservation will also be at the event and the organisation advised boat owners: “To avoid disturbance and harm to cetaceans and other marine mammals, the key take-home messages are: Go slow – stay back – don’t chase.”
