Narwhal 620 Samoa bound
19th October 2010
Apia Airport has taken delivery of a Narwhal 620 work boat. But
not before Boating NZ took one for a test drive.
Built in Spain, the 620 has just taken up a position at the Apia
Airport and will be fitted with four 30-man life rafts, ready to be
deployed if a plane goes down.
Boating NZ took the 6.2-metre Narwhal, distributed by RFD New
Zealand, for a spin on the Waitemata Harbour before it was shipped
to the Pacific Islands.
In a messy chop the 620 handled herself well, slicing the tops
off waves and keeping upright in the process. Three running strakes
on the fibreglass hull help her track straight while a turned-down
chine keeps spray away from the boat's occupants.
From the anchor locker aft, the hull is foam-filled, which makes
her certified as unsinkable and gives a quiet ride too.
A one-piece moulded deck acts as a false floor and means a
single scupper in the transom replaces a bilge pump. Getting on the
plane was easy with the 620's four-stroke Yamaha 115hp, and she
operates well with only a little air beneath the hull.
At 4500 revs - as far as we were allowed to push it on a tight
engine - she reached 27mph, but there's plenty of revs and
performance left. In the choppy conditions, she hugged the water
firmly but needed to be trimmed right in to avoid cavitation in
An extension of the deck mould runs around the tube for
protection while pressure release valves preserve the tubes'
integrity when subjected to extreme heat.
There are grab-handles everywhere and a 92-litre fuel tank and
fuel filter are housed inside the solid centre-console, along with
the battery. Seating is limited to a single above the anchor locker
but the 620 won't exactly be performing a sit-down job.
