Peter Smith, designer of the Rocna, has been building, racing, and cruising sailing yachts since the early 1960’s. In 1978, Pete walked away from his successful yacht production company Cavalier Yachts to go cruising with his wife Josephine. Thirty-three years and well over 100,000 nautical miles later, he\u2019s still cruising on his current yacht Kiwi Roa<\/em>, the result of over a decade of planning and design work.<\/p>\n\n\n\n

A boat-builder by trade, Pete built Kiwi Roa<\/em> over a five-year period to be his ultimate cruising yacht (her design philosophy matches that of the Rocna: bulletproof.)<\/p>\n\n\n\n

15m (50′) long, she is built from 10 mm aluminium alloy plate (up to 25 mm in some sections), displaces 27 tons, and is designed to withstand the worst conditions Mother Nature \u2013 or man \u2013 can throw at her.<\/p>\n\n\n\n

Pete, together with Jo and their son Craig, sailed Kiwi Roa<\/em> from England to New Zealand during the period 1994 \u2013 1998. Although extremely well set-up, Kiwi Roa experienced frequent problems when anchoring. Soft mud areas such as the English East Coast, the Chesapeake, and the Delaware Bay presented particular problems.<\/p>\n\n\n\n

Pete had used every type of anchor known to man. Kiwi Roa<\/em> carried a 110 lb CQR, an 88 lb Delta, and a 110 lb Bruce, but there was always a feeling of insecurity. So, in the New Zealand tradition of do-it-yourself, he built the first Rocna prototype, a 50 kg concept model which was tested during a circumnavigation of New Zealand. It endured hundreds of uses in conditions that included 70 knots on-and-off for ten days in Stewart Island, and 50 knots for two days in Akaroa. While other boats were having anchor trouble, Kiwi Roa<\/em> did not move.<\/p>\n\n\n\n

As word of the Rocna\u2019s formidable holding power spread among the cruising community, other sailors started to ask Pete for a Rocna of their own. Rocna anchors are now available in over 40 countries worldwide.<\/p>\n\n\n\n

Peter\u2019s recent sailing has been in the Atlantic, both south and north. After several years in Patagonia and Tierra del Fuego, and expeditions to Antarctica and the South Atlantic islands of the Falklands and South Georgia, Kiwi Roa<\/em> has been in South Africa and the western African coast before making the big jump to Newfoundland and Greenland.

Canada Metal (Pacific) Ltd brings a strong quality control background to the manufacturing of the Rocna anchor family. As the world\u2019s largest manufacturer of marine anodes, and supplier to the major marine engine manufacturers, we are extremely familiar with producing metal products to exacting chemical and dimensional tolerances.<\/p>\n\n\n\n

Since taking over Rocna anchor production, these quality control processes and procedures developed at our head office in Vancouver, BC, Canada have been incorporated into anchor manufacturing through our wholly owned subsidiary in China. Material traceability is one of the key elements of this program. Through tracking numbers embossed on every anchor, it is possible to trace the steel used in the anchor back to the original material certificates documenting its composition and mechanical properties.<\/p>\n\n\n\n

There are multiple inspection points during the production of every anchor, both at the sub-assembly level and at final assembly. Our inspectors take quality very seriously, and maintain extensive documentation on each and every production run.<\/p>\n\n\n\n

Robotic welding is used in the production of the anchors, to ensure consistency from one unit to the next.<\/p>\n\n\n\n

Hot dip galvanizing is used to ensure a durable finish, and is carefully monitored to ensure the composition and thickness of the galvanizing layer.<\/p>\n\n\n\n

The Rocna is an SHHP (Super High Holding Power) type anchor. During seabed testing for classification, Rocna anchors exhibited the highest holding power of any anchor that classification society RINA had ever certified. And when tested to destruction, Rocna anchors exhibit strengths up to six times the SHHP proof load requirements.<\/p>\n\n\n\n

Currently sizes 55 kg (121 lb) to 110kg (243 lb) (galvanized models only) are fully type approved and classified by RINA. We are currently in the process of updating the Rocna SHHP classification for the full\u00a0Rocna Original\u00a0galvanized product range.<\/p>\n\n\n\n

Rocna – The Original<\/strong><\/p>\n\n\n\n

ROCNA: CHANGING THE STATUS QUO<\/strong><\/p>\n\n\n\n

The Rocna anchor was designed by New Zealand sailor Peter Smith, who has been designing, building, and sailing boats since the early 1960\u2019s. Over 100,000 nautical miles of cruising, Peter experienced the same anchoring problems that are still prevalent today \u2013 needing to carry a variety of anchors to suit various seabeds, yet still the anchors dragged and boaters felt insecure.<\/p>\n\n\n\n

“Your anchor should provide you and your crew with reliability, security, and confidence,” says Peter. A lifetime of nautical experience worldwide was poured into an anchor \u2013 initially conceived for Peter\u2019s own use \u2013 which became the Rocna.<\/p>\n\n\n\n

AN INDEPENDENTLY TESTED NEW GENERATION DESIGN<\/strong><\/p>\n\n\n\n

Peter\u2019s solution consistently returns top results in objective and independent testing. Since its launch in 2004, the\u00a0Rocna\u00a0has led worldwide anchor tests as published in the likes of\u00a0SAIL<\/em>,\u00a0Yachting Monthly<\/em>,\u00a0Practical Boat Owner<\/em>,\u00a0Voile<\/em>, and others. Because of the\u00a0Rocna\u2019s reliable and convincing performance against its competition,\u00a0Rocna\u00a0is trusted to be rock solid in the real world. You don\u2019t need to take our word for it.<\/p>\n\n\n\n

FOR ALL WHO NEED RELIABILITY FROM PERFORMANCE<\/strong><\/p>\n\n\n\n

Rocna anchors are performing in some of the world\u2019s toughest locales, including Patagonia, Antarctica, Alaska, Greenland, Scotland \u2013 as well as enduring temperamental tropical weather. Rocna has “buy-in” from respected boaters whose opinions matter, from Steve Dashew to Jimmy Cornell. Southern lattitudes sailing pioneer J\u00e9r\u00f4me Poncet reports: “It took me years with many trials to achieve, in discovering the Rocna anchor, foolproof holding power\u2026”<\/p>\n\n\n\n

PRECISION SETTING<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The roll-bar (A)<\/strong> ensures that the anchor always arrives at the ideal angle for penetration, and the setting skids (B)<\/strong> guide the fluke tip (C)<\/strong> which acts as a sharp chisel cutting into the seabed. With a third of the anchor\u2019s weight on its fluke tip, an instant reliable set is ensured with every use.<\/p>\n\n\n\n

ROCK SOLID HOLDING POWER<\/strong><\/p>\n\n\n\n

Of all anchor types, a concave fluke (D)<\/strong> gives the greatest resistance, and through clever design Rocna provides the largest fluke area possible. In very soft seabeds, this provides the holding power to secure your boat. On hard or weedy sea floors, Rocna\u2019s chisel tip (C)<\/strong> ensures that it cuts through and bites deep.<\/p>\n\n\n\n

MAXIMUM VERSATILITY<\/strong><\/p>\n\n\n\n

The Rocna is a true multi-purpose anchor that sets and holds in most seabeds, from soft mud to hard sand, clay, grass, and kelp.<\/p>\n\n\n\n

RESISTANT TO WIND AND TIDE SHIFTS<\/strong><\/p>\n\n\n\n

A Rocna remains stable and buried, and does not roll out on reversal or veering of load, or if dragged beyond yield, providing enhanced security.<\/p>\n\n\n\n

HIGHEST QUALITY BUILD AND FINISH<\/strong><\/p>\n\n\n\n

Compare the welds and finish on a genuine Rocna anchor to alternatives. We believe a top performing product should be built like one, and we spend a lot of time and resources on production and quality control procedures to ensure that this is the case.<\/p>\n\n\n\n

HIGH TENSILE STEEL SHANK (E)<\/strong><\/p>\n\n\n\n

Rocna anchors are designed \u2013 and built \u2013 for strength and durability.<\/p>\n\n\n\n

SELF-DEPLOYING AND SELF-RECOVERING<\/strong><\/p>\n\n\n\n

The Rocna shank is designed so the anchor self-launches and self-stows on the majority of bow-rollers, with the greatest possible reliability.<\/p>\n\n\n\n

GUARANTEED FOR LIFE<\/strong><\/p>\n\n\n\n

Each Rocna anchor comes with a Lifetime Warranty<\/strong> against both breakage and bending in addition to manufacturing defects.<\/p>\n\n\n\n

COMPETITIVELY PRICED WITH WIDE PRODUCT RANGE<\/strong><\/p>\n\n\n\n

Rocna anchors are available in 14 sizes from to suit all vessels from small boats to small ships. Larger sizes available on request. Galvanized and stainless steel options are available in all sizes.<\/p>\n\n\n\n
