We have an oversize Rocna on our 331m (ie. next size up from Rocna recommendation). (having moved up[ from Delta) and we are well satisfied and sleep soundly on anchor. We usually experience 60-70 knots probably twice during our trips to Ionian. However, as important as the anchor is the chain! We have 80-90 metres of 10mm chain and usually anchor in depths of around 5-6 m.
We are satisfied with this. Trevor and Sally Doran – Dreamcatcher.
