US-based Shore Excursions Group is looking to gain a foothold in the UK.
Former Silversea UK and Middle East senior vice president Trudy Redfern is to spearhead the UK expansion.
The company offers more than 5,000 excursions and tours in 500 destinations.
Shore Excursions Group will be trade focused, with a dedicated UK reservation unit, freephone contact number for agents, together with localised support for agent contact and training.
Owned by former cruise executives Brad Miller and Michael Bonner, the company was established in the US in 2009.
The joint owners have experience working for Royal Caribbean International, Celebrity Cruises, Viking River Cruises and Abercrombie and Kent.
Co-owner, Miller, said: “The UK is a leading force in the global cruise arena. The market has enjoyed considerable growth in recent years, we believe this will continue.
“The Shore Excursions Group has already received a considerable amount of interest from the UK and we now believe the timing is right to enter the market to capitalise on existing partnerships and work with agents to help them grow their cruise business and optimise this incremental source of revenue.”
