Low-Weight Aluminium Davits Proving Beneficial to Naval Operators

Aluminium davits

Latest reports suggest that aluminium davit weight advantages are swaying owners in new markets to look again at the structural alternative to steel.

Aluminium davits are long-accepted by navies, coastguards and fast-ferry operators.

The Australian Border Protection recently decided to equip two more Cape-class patrol boats with PLAR-6500 aluminium davits from Vestdavit, having already installed 16 units on its eight new patrol ships to lift 6,500 kg rigid-hull inflatable boats (RHIBs).

The self-tensioned davits feature shock absorbers, guiding rails, wire haulers, and independent HPUs, which all help towards safely launching and retrieving boats at up to 10 knots in the heavy seas that stretch from the tropics to the Antarctic.

The lightweight option is also preferred for fast patrol boat applications by the Royal New Zealand Navy, the Danish Navy, the Swedish Navy, and the US Coast Guard.

Security authorities are also operating fast response craft in the Middle East, and South Asia are newly engaging with the benefits conferred by the aluminum davits in the 850kg-7,000kg safe-working load range offered by Vestdavit.

Every kilo saved in onboard equipment weight can enhance vessel stability and add payload.

The aluminium davits are 30% lighter than their steel-structured equivalents, while it also brings a tangible stability gain for lighter duty vessels. The davits also minimise corrosion and are non-magnetic.

With the davits, vessels have better maneuverability, lower fuel consumption, greater speed responsiveness and an expansion of its operational window.
