Don't really see the point but interesting to see how strong these boats appear to be;

Well I enjoyed the video. However the question would be how do other similar boats fair in similar collisions. Quite OK I suspect. A yacht has to be quite robust in the bow area to provide the stiffness needed to support the power of the jib.
The areas of susceptibility of a yacht are the near flat areas of top sides and bottom where a sharp corner of something like a shipping container could rip it open. I doubt the Dehler is any different.
Certainly smaller yachts would have no trouble reproducing these tests it is the mass hence inertia of a boat that has to be dissipated in collisions like hitting the stone breakwater.
To smash through the floating barrier with the keel doesn't mean much when the keel has the major inertia and is cast iron.
One of your main problems is the inertia of the crew as they crash into the cabin on sudden stop. (seat belts needed).
good stuff olewill (tempted to recount some collisions over the years but won't) The worst damage ever suffered was when another boat hit Howzat mid ships at the gunwhale. Even that was easily repaired.

Yuck - I know it is all done deliberately but it still makes me cringe !
