Simply take a photo or a video of one of the marinas owned by Premier - which includes Eastbourne's Sovereign Harbour and email it in. Photographs should be JPEGs and a maximum of 5MB. Videos should be MPEGs and no longer than 2 minutes.
Each Friday, the judges will pick their favourite photo or video from all the submissions that week. The winner will get £100 and their picture will also be put forwards to the grand final where another £500 is on offer! Be quick to get into the first draw - submissions must be made by 3pm this Friday! - although there are then three more chances to enter.
The four closing dates are Friday 10th August, 17th August, 24th August and the 31st August.
Full terms and conditions are on the competition page. It has been taking several minutes to load for me though, so you might want to go and make a cuppa while you wait!
