The number of motorbikes coming over for this TT is up by more than 10 per cent on last year.
A removable mezzanine deck on the Steam Packet's fast craft Mannanan is allowing an extra 100 bikes to travel across from the UK per sailing.
More than 13,500 bikes are already booked to come over for this year's event.
Steam Packet CEO Mark Woodward says extra bikes on board won't affect the safety of other passengers:
