Fuel consumptionRichTS asks I’m looking to buy an
old 35-45ft Princess with twin diesel
engines, something like a P35 or P45.
Budgeting for fuel consumption is
proving a tricky task. It seems that with
boats of this style and age, 1mpg is a
reasonable estimate at planing speed.
My question is, what about at pottering
speed – the slowest speed you can still
maintain control and forward movement
in the Channel in fair conditions?
Murv says Our boat is a 42ft 1989
Fairline Turbo 36 powered by twin 306hp
Volvo TAMD61As. Being so poor as to
make the average church mouse seem
positively affluent, I was a bit concerned
about the running costs and keep
detailed records of hours run against
fuel added. We’re based on a tidal river
with a 6-knot speed limit, so most of our
boating is pottering around with the odd
faster blast further downriver. Over the
first year, we averaged 8.84 litres per
hour. With a coastal crossing using a
mix of slow planing and displacement
speeds, we burned 30-54lph.
jrudge says Fuel consumption at
displacement speed will be very low
but do bear in mind planing boats are
designed to be comfortable on the plane.
Unless the water is very flat, it will tend
to roll and be uncomfortable. There are
plenty on here that pootle but for it to
be tenable, you do need flat calm seas.
Sprocker says I recently became the
owner of a Princess 40 of 1998 vintage
with Volvo TAMD63P engines. These
are the figures I was given at the time
for cruising at displacement speed:
1400rpm 9.3 knots while burning 26lph
for 1.58mpg.SUBSCRIBE TO MBY SAVE UP TO 39% WHEN YOU SUBSCRIBE TODAY! See page 56

& River Trust enabled the contamination
to spread up and downstream over five
miles of waterway.
By the Environment Agency’s
own calculations, 80,000 litres of
oil-polluted water has been removed
from the contaminated area since the
incident. The Swan Sanctuary rescued
more than 30 swans and other waterbirds.
Many other animals died.
Local residents, businesses, rowers,
walkers, tourists and liveaboard boaters
have been subject to harmful fumes, along
with the sight of dead and contaminated
wildlife, not to mention the toxic waste
itself. Some local river-based businesses
and organisations have had no option
but to cease operations during this time.
This must ever be allowed to happen again.
The Lea Boaters CollectiveThe photographs look
horrendous. While I understand
your frustration at the speed of response,
it’s whoever caused the spill that should
be the real target of everyone’s anger.
I hope the mess is cleaned up as much as
is possible and proper systems are put in
place to stop this happening again. HugoEarly riser Nathan Ellis got up at the crack of dawn to capture
