The Hull and Humber yacht arrives in Hull in July
The Clipper race fleet is to arrive in Grimsby 24 hours earlier than scheduled because of a predicted storm.
The threat of winds above gale force eight on Friday has forced the yachts to berth in Grimsby marina on Thursday.
Next week, the yachts will move from Grimsby to Hull where this year's Clipper Round the World Yacht Race will begin on 13 September.
The race sees 10 identical 68ft (20m) yachts manned by amateur sailors cover 35,000 miles (56,000km) of ocean.
The race was founded in 1996 by Sir Robin Knox-Johnston, the first man to sail solo and non-stop around the world.
