I think another outstanding yacht photographer is our YF member Christo303. His most popular photo is probably "Pelorus" moored in Antibes at night and often used by Lürssen. Check out his photos most recently from yachts off Sardinia and many more..Keep up the lovely work man! https://www.flickr.com/photos/christo303/
I had the pleasure of working with Dick Holthuis, whom I didn't see mentioned here yet. Very professional, and very nice person to work with. www.yachtimages.nl Dick Holthuis | Professional Photography and Video.
