Heritage Group, of which Lefebvre is chairman, will take an 85% stake and Kent, who founded Abercrombie & Kent in 1962, will receive a 15% share.
He will continue in his role as chairman and chief executive, while Lefebvre will become chairman of Abercrombie & Kent Holding.
The deal is expected to be completed later this year, subject to closing conditions and regulatory approvals.
It is a separate investment by Lefebvre-led Heritage group and does not involve Silversea.
In October 2017, Chinese real estate and investment company Zhonghong Group completed its acquisition of 90.5% of Abercrombie & Kent for $412 million, with Kent retaining his ownership stake.
Speaking to TTG, Kent and Lefebvre said they had been friends for more than 20 years but “accelerated” discussions of a potential partnership last September.
Kent said Abercrombie & Kent would “continue just as normal with no change at all” to its running and use the investment of Heritage to make acquisitions and expansions to its operations.
Lefebvre said: “Geoffrey has a long queue of financial investors wanting to work with him, so I’m delighted he chose to partner me.
“I think he wanted someone with a similar background to him – a travel entrepreneur in the luxury space – who shares his values.”
He described how Heritage and Kent would continue growing the business and then "look at areas that can be added later”.
“We can expand DMCs, Abercrombie & Kent’s unique product – we can expand that too... we can look at it all,” he said.
Kent, added: “In this industry you need a partner to go through good times and bad times with, and Manfredi is someone who we can make decisions with together."
