| Ultra-high holding power Independant Testing
(see test results below) have proven that a Rocna possesses stopping power vastly superior to
equivalent weight plough or claw types in soft sand or mud, due to the
large blade area coupled with the blade's concave shape, which offers
the greatest resistance of any form.
Instant setting A
Rocna always attains the correct attitude for penetration, and with its
combination of chisel tip, roll-bar, and skids, is rapidly buried on
most seabeds – typically within one meter.
Large blade area and chisel blade tip On
a boat weight matters, and in a Rocna anchor every gram of metal is put
to use. A large concave surface blade area offers superior holding
power, and the chisel-like blade tip easily penetrates weed, grass, and
kelp
Roll-stable A Rocna
is not susceptible to sudden "trip out". Owing to its optimized
geometry, it remains embedded, and does not roll out on load-reversal
or if dragged under extreme load.
Ease of use A Rocna
self-launches and locks home on most bow rollers. A tight curve radius
between the shank and blade give a positive lock, preventing movement
at sea. The slotted shackle attachment point allows single-shackle
fixing, and special holes are positioned for a buoyed retrieval line
and tandem anchor, if required
Roll-bar A
Rocna’s roll-bar ensures that the anchor will turn itself to the
correct attitude for setting, every time. The skid-rails then direct
the blade into the seabed. This also eliminates the need for dedicated
tip-weight (an inefficiency common in other designs)
Versatility There is
a Rocna to suit your boat, whether she's a small runabout or a vessel
displacing 50 tons. Larger sizes can be custom designed for your vessel
(please enquire)
Rugged strength The
heavy-duty construction of a Rocna is attained through clever design
and the use of Australian Bisalloy BISPLATE 80 steel. A Rocna is rock
solid with no moving parts, eliminating complex adjustment systems and
potentially dangerous failure points
Durable A hot dip
galvanized finish covers the entire surface of every Rocna with
protective zinc, including the interior of the hollow rollbar |
