I would be interested, but just a word of negativity... I took 2 ww cruises from the Gold coast last season. Only finished up with a few half decent shots, too many point and shooters and phone camera photographers to get a half decent position (without throwing them overboard).
They were rude, ignorant, stupid and childish. Wasn't good for photography at all really. But a fantastic experience.
If we could get enough numbers to hire the entire boat, I'd be very, very interested
