Watch the video and see where the anchors being tested are all being pulled on hard dry sand, then when they show the Ronca at about 5 1/2 minutes in you'll now see it in muddy sand. The substrate is entirely different. IMHO that is dishonest!
Now; don't get me wrong, I think with watching other cruisers the Rocna is getting a good reputation. We don't have the extreme results yet. I watched a Swan in Falmoth harbor anchor and drag half way across and out of the channel. When he tied up next to a friends boat he pulled up a tire. Perfect shot!
