100m+ megayacht design

Hi there,

I'm new to this forum, and thought I'd introduce myself and what I'm doing here; my name is Sam, I'm a megayacht designer working in the UK and am still learning about the demanding design requirements of the high-end (100m plus) megayachts. This forum has been a great research tool since I started this job. I'm currently creating a 100m++ megayacht to display the cutting edge of technology in green energy sources, security, safety, nautical and AV technology, and was wondering if you had any suggestions as far as these go considering the size, expense and requirements of such a large vessel. I'm talking alt-energy, anti-piracy/terrorism devices, modern/future nav systems etc.

any help would be much appreciated
