Thousands visited the St Helier Marina to have a close look at more than 60 boats, try out various activities and visit dozens of stalls.
Vessels worth over £20 million were on display, with the biggest boat being a 70-foot Princess motor yacht, worth ?1.4 million.
The show was organised by Jersey Harbours in partnership with Collins Stewart.
‘Initial feedback from exhibitors has been excellent,’ said Harbours chief executive Howard Le Cornu.
‘With around ?20m worth of boats on display, business has been brisk for our wide range of exhibitors and activities.
