Claire Rose becomes senior business development manager, while Charlotte Ireland becomes business development manager.
Rose takes on additional key accounts, as well as responsibility for managing Seabourn's general sales agents in territories such as South Africa.
She joined Seabourn three years ago, and was previously a business development manager.
Ireland, meanwhile, steps up to the role of business development manager "in recognition of her success developing new UK accounts and growing their business", said Seabourn.
She joined the line in 2020 as business development representative, and has since 2022 served as an assistant business development manager.
