I bought my 40 kilo Rocna back in 2012 and had it shipped to Fiji after I got tired of my CQR not setting on the bottom. I made sure to get a bigger size than my boat needed(45 foot but weighs 45,000 pounds) as I like to sleep at night. It's held us in 55 knot winds while we were anchored in Fiji at one of their islands and everywhere else. Now in the Caribbean and it's still doing a great job. At one anchorage, it was said to have a hard sand bottom and others had had problems setting their anchors. I dropped ours and went diving on it just to see. It had hit the bottom and within 4 feet was just about totally buried. So much for "hard sand". One of the best investments I've made for our boat. Great job!!
