This topic has been covered elsewhere, and the biggest problem is entering foreign ports with different gun laws than ours. A enfeild wouldnt draw much attention, nor would a stainless steel 12ga, if stowed in a locking cabinet, but a SKS would be harder to explain. Most of the areas mentioned in the articles are unsettled and unpoliced by civilezed nations, leaving You on your own. A enfeild or two would be very useful at longer ranges but how do you determine who to target?, and at what range?. Most of these "Pitrates" are stealing from the rich, and sometmes these stolen boats are used as "Grasshoppers" running drugs into our ports until the boat attracts attention enough to warrant scuttleing her. The crews on these stolen vessels are dumped when they take over, and then they go about running the buisness of drugs.
