I’d only change one thing. Rather than one $30-million yacht, I’d do 10 3-million yachts. Each with a BOFORS on the foredeck (suitably camouflaged, of course), and a couple of M-60s with rail mounts for cleanup. I’d rotate them through the area a few at a time, so the pirates wouldn’t be able to figure out who was thinning their numbers.
Figure 2-3 at sea at any given time, so that boosts the fuel costs and the number of crew needed (though not by the full amount, since the smaller yachts won’t need the big crew that the big one does), but increases the number of passengers as well. It also increases the number of pirates that can be dealt with during each sailing. Plus, the costs might even be lower, since it’s likely that I could probably round up a sponsor or two due to the interest that so many have in making that area safe again.
Well the only problem is attracting the clientelle that’d pay 100k / week. Doubt they’d sail on the 3M yacht - not much of a motorboat for that kind of money, and profitability would be less. That does not really increase the passenger capacity as the 3M boats are much smaller while you still need the same crew for passenger security. Also you decrease the amenities, as well as increase the risk of loss of a ship. They might shoot back and a smaller boat is more likely to take accidental critical damage.
While that’d certainly be more effective at reducing the pirate population we’re talking about making money here... :)
Ya know this is the only place where one can discuss these things (semi seriously). :)
