The Steam Packet Company says it's seen a 2.8 per cent rise in TT passengers this year.
And the number of motorbikes travelling to the festival on ferries also saw an increase - up 6 per cent on last year.
Chief Executive Mark Woodward says in total the company brought more than 14,000 motorcycles and 36,500 passengers to TT 2017.
He says he's pleased with the rising numbers of fans wanting to come to the racing:
