I thought the YM article was rather alarmist because it probably put most people off ever buying a Rocna.
I got one one of the first ones into the UK when the distributor was based in Ireland for the British Isles.
I have a 15kg one on my NC321. It replaced the lovely stainless Bruce one supplied by Nauticat. However I got the Rocna because I had two bad experiences with the Bruce and in general found it very difficult to set in typical places like Studland Bay, Osborne Bay, Newtown Creek.
Getting the Rocna was a revelation because of the speed of setting and the incredible holding. I do not understand why boat builders don’t fit these moderrn style anchors on all boats.
I also have a New Zealand made device at the other end of the boat, a KiwiProp. This is another great item – a lightweight plastic feathering prop which transformed how my boat handles when in reverse and also gives at least half a knot extra boat speed when sailing.
