control either at the helm station or that cockpit
station. Ten, with the touch of another button,
control is transferred to the steering wheel and twin
throttles and we’re away.
With Volvo’s ‘trim assist’ activated, you don’t
even have to worry about adjusting the trim as the
Riviera powers up onto the plane – the boat does
it all for you, keeping the ride level rather than
bow-up. You can, of course, also manually tweak
the ride and fuel efciency when running in more
of a sea. And with electronic steering, the helm’s
exceptionally light and responsive.
With a boat this size, packing that much
horsepower, you’d expect to burn through a fair bit of
fuel. Interestingly, though, the fuel usage per nautical
mile covered doesn’t vary that much as you move up
the speed range.
Starting with 5 knots in the marina, then 12
knots in the speed lane down the harbour, we
opened her up once we’d passed Orakei – into the
20s and then 30 knots, leaving the camera boat
in our wake [bloody show-ofs! Ed]. Watching the
fgures on the big screen, we were burning 6.6 litres
per nautical mile at 20 knots, 6.7 litres/mile at 27
knots and 6.8 litres/mile at 30 knots (all in fat
water). Tis Riviera has a cruising speed of 27-29
knots and does 35 knots fat out.
Once the camera boat catches up of Waiheke,
we make the most of the fat water to do donuts at
25 knots for the photographer. Te 4800 is easy to
steer into big curves and swoops, and makes short
work of its own wake when it crosses it.Auckland’s most modern dry stack
