You are wrong two ways:

1. The SA-6 does have on-board radar. Yes, it can be guided from an AA radar on the ground, but that is to bring it to within the range of the terminal guidance system, which, on an SA-6, uses an on-board radar. Several mobile AA missiles work this way. The SAM-6 is probably the cheapest and most available to terrorists.

2. The Cole was hit by a fiberglass hull boat that contained hundreds of pounds of high explosive. I don't know that your could carry a bomb that big on the open deck of a Zodiac. I recall reports of the terrorists spending most of a year building the boat.

"The SA-6 does have on-board radar."

I'm afraid you are a little confused. The SA-6 missile relies on semi-active terminal guidance to guide it to impact. That means that a ground based radar must illuminate the target with radar energy that the missile then homes in on. The missile itself does not have an active radar. Very few missiles do. In fact, I think the only ground launched anti-air missile that does is the ground launched variant of the AMRAAM missile.

"The Cole was hit by a fiberglass hull boat that contained hundreds of pounds of high explosive."

Almost every eyewitness and official account describes the boat as a Zodiac. Some Zodiacs have a fiberglass hull, but regardless, they are small and couldn't carry a truck, nevermind a missile system.
