"...The Rocna has gained considerable acclaim as a general purpose anchor with tests and experience claiming increased holding and diversity compared to other types and its ease to stow on a bow roller."

Arctic Tern, a Bruce Roberts 434, recently complete the North West Passage, sailing 6250 miles from Newfoundland to Alaska using a Vulcan 33 as their primary anchor.  Some of the comments we received on their experience include:

“We have been impressed with the ease of launching that the curved shank facilitates, previously we used a Rocna which always needed encouragement to leave the vessel. The speed with which the anchor set and subsequently held was second to none. We have had wind speeds of up to 55 knots in one anchorage and it held solidly, bottom was hard fine stone and sand. Other vessels in the same anchorage were not so lucky.

Retrieving the anchor is a dream with smooth action as it returns over the bow roller with no snatch and violent action as the shank passes the roller furling drum.”

We were highly satisfied with the performance of the 20 kg / 44 Lbs Rocna Anchor on our Back Cove 37.

Fit launch and retrieval were flawless with no modifications to the stock windlass, platform, or roller. The boat LOD is 38 ft; displacement 21,000 lbs.

We had specified 5/16 in / 8 mm G4 all chain rode. We set at 5:1 scope.  We had many nights of persistent 20 kts with gusts to 25 kts in anchorages exposed to wind. We had at least one night of persistent 25 kts with gusts close to 35 kts. We dragged only once in an anchorage at 20 kts. On retrieval we found we were in a very weedy bottom. We re-anchored in deeper weed free waters with an immediate and perfect set with no problems in persistent 20-25 kts during the night.

Anchors, or the advantages and disadvantages of the various types, are rather a popular subject. After our attention on the remarkable Hydrobubble option, we were pointed by several readers to the Rocna anchor. The concept has been designed by a New Zealand yachtie, and therefore is subject to a lot of experience and expertise.

How do you choose an anchor? Are you looking for a ‘lunch hook’ or heavy-duty hardware on which you can stake your life – and your H yacht – when a storm blows up and turns the anchorage into a maelstrom?

West Marine’s line-up of fourteen anchors included several anchors that are just copies and/or variations of other types. Such copies present concerning the West Marine / SAIL testing a tempting option, since they are usually cheaper than the genuine article. However, when a copier makes his imitation, he has two options.

It’s been three years since we launched Growler, So over this season, I decided to try a couple of new our 36-foot lobster boat. We’ve taken her to the products and update some equipment already on board.

Long distance cruiser and boat builder Peter Smith designed the Rocna anchor, then tested a 50Kg prototype on his yacht, Kiwi Roa, during a circumnavigation of New Zealand. I borrowed a 25Kg version for my 12 metre Ganley cutter over the summer

Many sailors will remember Peter Smith as the founding partner of Cavalier Yachts from the days when New Zealand was still building production yachts. In the 20 or so years since then he has delivered yachts and built boats all over the world. An issue that always arose was the choice of anchor, with both clients and friends complaining about each anchor’s peculiarities.

Peter, the founding partner of New Zealand’s Cavalier Yachts back in the 70’s, has returned to New Zealand after 20 years of professional sailing, yacht deliveries, and boat-building all over the world, including 10 years running his own yard in Colchester, England, where his current boat Kiwi Roa was built.
