The Show opened yesterday (Friday 21) and runs throughout Saturday from 10:00 to 18:00.
Access to the pontoons is from Crown Pier, and some parking spaces have been closed off throughout the show.
David Norman, President of the GMTA, is thrilled with the return of the event and says there should be something nautical for everyone to enjoy.
“There will be a marquee on the end of the Crown Pier with land based marine exhibitors and also food and beverages on offer,” he said. “Various marine traders will be displaying their latest maritime equipment and a good variety of motorboats, and some yachts will be on show.”
Guernsey Ports are also on hand offering support and information to boat buyers and mooring holders, as well as providing key information on waiting lists, allocation processes, registration, and the coastguard.
Kieran Higgs, Assistant Harbour Master, said islanders will be able to see the Sarnia workboat and dive barge in the marina.
“These are fascinating crafts bespoke to all sorts of marine engineering and maintenance support across both our harbours. We will also have our Harbours rib and staff on site talking about a variety of roles they play at Guernsey Ports and the RNLI,” he added.
