We are talking about the future of yachting. Fort Lauderdale is only one point on the moving map of yachting. This is a worldwide industry with most of the major players in places other than here. I see you haven't dealt with many owners The small boats (<30m) owned and operated by retired couples may be a good target for some greening but that same demographic is limited in the money they have to invest in green for green sake and may be unwilling to invest a million in efficienty enhancements to save a hundred thousand during their period of ownership. The owners of large yachts demand luxury, they get luxury, and they charter their boats to people just like themselves. They demand and pay for the most luxurious experience afloat. The cost of fuel is only small part of the operating costs. A typical 50 meter boat might burn $250 to $300 thousand a year in diesel, plus about the same amount just to haul it back and forth between the Med and the Caribbean. No big deal though, that is about a week's charter fee for many of the boats most (many) of us are talking about. The next generation of owers and charterers won't be any different. If nothing else they will demand more and more of newer and more extravagant. That is not to say the next generation of boats won't incorporate some very innovative and exciting developments but most of them will be driven by regulatory actions, not benevolent environmentalism. There are real benefits to cleaning up exhaust emissions, reducing or eliminating wastewater discharges, and experimenting with new technologies for publicity or charter marketing purposes but don't kid yourself about a green revolution in the large yacht business. Put down your Kool-Aid glass for a moment and look around. The US is the world's second largest economy very close behind the EU, China is about 20 percent of the US. Most of the yacht builders are spread around Europe but the US is still a major player and will remain so if not actually grow. Don't judge the market or ownership by the flag on the stern, Grasshopper.
