Hmm...So would you advocate something like an optional USMC detachment for US-flagged ships in the region, Royal Marines for UK-flagged ones, etc.?
Such a solution might not be practical and I think the payment issue might lead to some politcal problems. (The fee could make the professional military involved in the security operations appear to be "mercenary.")
I think perhaps that people are missing the point here. Piracy is very much like "bad behavior" outside an English night club. The solution is (or was) to put security cameras up. All this did was move the problem away from the security cameras. So too with patrols and piracy. The behavior literally evolves away from the patrols.
The other key point is training or lack of. The best asset a tanker has doing 8 knots, is not armed guards, or even an escorting destroyer. It is it's mast height and the crappy 10cm radar sitting on top. At a minimum it gives you an 18NM horizon that a pirate simply does not have. The problem is that the merchant game is all about money. So the Nav equipment is the cheapest that can be purchased, yet still satisfy regulations. Cheap Nav equipment and economic drivers also mean you are not going to get armed guards to be a common occurance.
Having said that insurance companies can drive regulation. So it would follow that an insurance company can lower the premium on a vessel that is equipped with a good, better, best radar and lower again if the crew are trained how to use it properly to identify and avoid pirates. That means creating 3 or even 5 passage plans in advance to compensate for varying situations and actually keeping a good look out as per the rule of the road.
Even at 8 knots you always have the upper hand as the pirate cannot see you and you can see him, simply because his horizon is 6NM even with a radar. But there is also another asset that the pirate doesn't have and that is called energy. Merchantmen are marathoners, pirates are sprinters.
If you follow this approach then you can target escort missions to spots where the merchantman cannot avoid the confrontation. This makes the military operations more efficient and more likely to bag a couple of pirates, who for the life of them can't figure out why they are not catching as much game as they used to. i.e. Plays on their frustration.
It follows that if you are in a ship that can do 27 knots with the same 3 to 1 horizon advantage then it is nearly impossible to intercept and even if you did make an interception you (the pirate) would burn more fuel than you could afford. Increasing speed in a Bangkok Taxi creates a
"business decision event" for the pirate. The old hands know how many minutes they can chase at 60knots and the green horns are left floating for days wandering what happened.
Anyway, that is the approach I would suggest for Socotra and it's surrounds. The TSS coming up around Djibouti and Yemen, funnily enough is where you need patrols as it limits maneuver. The Horn of Africa and the Strait between Socotra and the mainland is not really an issue.
It really is all about energy and maintaining it. The nature of the terra firm and the tidal currents there allow you to spot the guy and lead him one way and then use maneuver to make him think about his hard fuel choice. In other words, know the tides in key bottlenecks and use those tides against the pirate. If he's a green horn he'll be in the strait where the current is just that .5 of a knot faster. Sucker him in to commiting and then go the other way. Even a 1 knot current against a speed boat equates to an exponential increase in fuel consumption. Do the math. At 60 knots he burns , say 10 gallons a minute. At 61 knots he burns say 12 gallons a minute and so on.
As to turning into a threat desribed by Gf. There are 101 ways to skin a cat, but my preference was to always turn away and make him do the work. A pirate on your stern suffers a huge time penalty (from his perspective) and therefore fuel burn if you make a 5 degree alteration of course. It adds something like 5 minutes to his boarding attempt. As the range decreases you zigg and zagg, drawing him out , making him work and funnily enough, in any sort of seastate sometimes you draw away from him and then "do a Bismark" when he is at the limit of his horizon to shake him off.
This really isn't rocket science. Just watch Animal Planet and a Cheetah trying to chase down a Wilderbeast or a Gazelle. The Cheetah has a bigger kill zone radius then the lion because of it's speed, but pirates don't have the eyesight of the Lion or the Cheetah.
