The Queen Mary takes on a magical illumination at this hour and your DPA instructor will help you capture it with demonstrations and supervision on composition and camera setting expertise.

As for the light house and its reflection in the adjacent waters, try the Rule of Thirds in your composition versus dead center to choose which you prefer as a fit for your signature style of shooting. There is no wrong approach and such considerations, discussed with your co-participants and the instructor can also apply toward a myriad of choices with so many photo ops in the harbor and marina as well. It is hard not to get something good at sunset.
