Just as reference, for those who haven't been around water areas for most of their lives. Ever see an RV that's been in a serious accident, how they just completely come apart with thin material and insulation all over the road, all structural integrity gone?
That's what pleasure yachts look like if they hit together hard. Then they generally catch fire and burn to the waterline in minutes (fiberglass resin, once it gets going, you have seconds to toss the raft pod and dive after it, it goes up fast), or sink. I'd seen a few do that in S. Florida.
Yachts are not made to be impacted by anything. If they'd been "rammed", they would not be there.
Edit: I just looked at the missile boat photo. 498 tonnes. If they'd been rammed by that, there'd be two halves of a sinking boat and burning fuel on the water. Likewise if they'd been "fired on"...with 20mm Oerlikons? It'd have been chewed apart with one burst. Idiots.
