Lloyd's Roofrack Extension
To construct the SM-MCC-CTR-001 (Smith Model Multiple Canoe
Carrying Car Top Rack #001) You will
need; o A sheet of plywood o A circular saw or table
saw o Wrenches or a socket set o 4 U bolts or
car muffler clamps (I used 2 inch) o 6 eye bolts o 20 large washers to fit the above
hardware
 To start; · measure the distance between your
cars roof rack bars (say about 2 feet) · Take some ½ inch or ¾ plywood and
rip it with a circular or table saw so it is about 4 or 5 inches wider than the
distance between your rack bars on the outside edges. A couple inches on the
front and back of the bars will be needed to bolt to later. · Cut your plywood
to the width of your two canoes plus about 6 inches. This is usually about 6
foot 6 inches. You will want an inch or so between them and a couple inches on
the outside edges to install eye bolts to tie to. ·
With your plywood now cut to shape, find the center and draw a line
across dividing it into two halves roughly 2 feet by 3 feet. On this line
measure in a couple of inches on both sides and mark a drill hole for your eye
bolts. Be sure that your drill holes are both towards center enough that your
eye bolts will miss the roof racks bars. If in doubt put the plywood on your car
top to check things out before drilling.
 · Measure in from both outside edges now a few inches and
draw lines to find the drill holes for your outer eye bolts. The side eye bolts
should be in from the side, front and back a few inches for extra strength when
you tie to them. · Install all six eye bolts with
large washers top and bottom. My eye bolts are rated for 80lbs. You may use a
hacksaw, metal saw or grinder to shorten the excess length of the eyebolts if
you wish. Be sure they are very tight though. ·
Place the plywood on the roof rack and center it left and right, front
and back. Measure in a few inches from the tips of your roof rack bars and mark
the drill holes for the U bolts, this can be done by pencil or by
pressing the U bolt into the soft plywood to make an imprint then
penciling over the mark. When all 4 are marked take the plywood down measure
everything again and straighten things up and drill your holes slightly larger
than the diameter of the U bolt.
 · Now place the plywood back on the car top, center it and
install the U bolts as tight as you can with the last of the washers on
top and you are done
A few notes: o
You could use two more U bolts in the center if you wanted to, it
is a bit overkill but it makes the contraption a bit quieter. o I used thinner plywood on mine because it was free
so to compensate for the reduced strength I doubled the thickness on the
edges. o If you remove your roof rack for
yearly maintenance like I do you will have to put it back exactly in the same
place for the double carrier to fit back on again. o
This drives like a dream with two canoes on top slightly pointed in at
the front but is very strange to drive with on windy days with no canoes on top.
It is best to remove it after every trip as it goes on and off in minutes once
you get used to it. o You will never get into
a car the same way ever again after using this. The first time you smash your
head or scrape yourself on the bottom of an eye bolt you will forever look like
you are getting into a helicopter. o Finally
with the bolts sticking up on the top you have to be careful not to scratch your
gunwales with them. You could cover U bolts sticking up with something
though but on the 001 and 002 models I haven’t done this yet.

Some Legal Guidance
Please, please remember that it is not simply a question of the overhang at the
front, rear or sides.
What would worry me most is the size of the load
being carried on some quite small vehicles. Add to this the effect of wind,
particularly a side wind on a canoe (or two canoes) on the roof of a small car
and you go beyond the simple regulation dealing with overhangs.
The text
of my original post in the other thread is.....
"There is no
legislation which deals specifically with roof racks.
There are
various bits of legislation which deal with the safety/security of loads, the
use of the vehicle in a manner which may cause danger, maximum vehicle lengths
and widths and overhanging loads.
They legislation is set out
below. My interpretation is that a load projecting a few inches will not in
itself fall foul of the regulations.
Putting an excessive load on
the roof rack may cause problems due to weight, size or poor security. The
problem would be if it was insecure or in some way adversly affected the
performance / ssafety / handling of the vehicle so as to cause danger. Clearly
if a load projected to the extent that it caused a danger then it would be an
offence.
So whilst I can carry two canadians and two kayaks on the
roof of my 110, doing the same on a Ford Ka would clearly be illegal because the
nature of the load would render the vehicle unsafe and the overhangs would also
be too great.
I have simplified the below text in some places in
order to make it more easy to understand, so it is not a complete quote fromm
the legislation.
Regulation 100 of the Road Vehicles (Construction and Use) Regulations
1986 provides for the maintenance and use of vehicles so that no danger is
caused.
100(1) A
motor vehicle,
every trailer drawn
thereby and all parts and accessories of such vehicle and trailer shall at all
times be in such condition is caused or is likely to be caused to any person in
or on the vehicle or trailer or on a road.
The number of passengers carried by such vehicle or
trailer, and the manner in which any passengers are carried in or on such
vehicle or trailer, shall at all times be so that no danger is caused or is
likely to be caused to any person in or on the vehicle or trailer or on a
road.
The weight
distribution, packing and adjustment of the load of such vehicle or trailer
shall at all times be such, that no danger is caused to any person in or on the
vehicle or trailer or on a road.
100(2) The load carried by a motor vehicle or
trailer shall at
all times be so secured, if necessary by physical restraint other than its own
weight, and be in such a position, that neither danger nor nuisance is likely to
be caused to any person or property by reason of the load or any part thereof
falling or being blown from the vehicle or by reason of any other movement of
the load or any part thereof in relation to the
vehicle.
100(3) No
motor
vehicle or trailer shall be
used for any purpose for which it is so unsuitable as to cause or be likely to
cause danger (see note below) or nuisance to any person in or on the vehicle or
trailer or on a road.
Section 40A of the Road Traffic Act 1988 creates an additional offence of
using a motor vehicle in a dangerous
condition.
A person is guilty of an offence if he uses, or causes or permits another to
use, a motor vehicle or
trailer on a
road
when: (a) the condition of
the motor vehicle or trailer, or of its accessories or equipment,
or (b) the purpose for
which it is used, or (c)
the number of passengers carried by it, or the manner in which they are carried,
or (d) the weight,
position or distribution of its load, or the manner in which it is
secured, is such that the
use of the motor vehicle or trailer involves a danger of injury to any
person.
In
relation to loads much confusion is caused by there being separate offences. The
difference is that section 40A requires the weight, position, distribution, or
manner of carriage of the load to be such that no danger to a person is
involved. Regulation
100(2) (insecure loads) requires that it be
secured and in such a position that neither danger nor nuisance is likely
to be caused.
Regulation 11 of the Road Vehicles (Construction and Use) Regulations
1986 refers to the permitted overhang on certain classes of
vehicles
Heavy motor
car
and motor
car -
the maximum overhang is 60 percent of the distance between the
transverse
plane
which passes through the centre or centres of the foremost wheel or wheels and
the transverse plane which passes through the foremost point from which the
overhang is to be measured.
Regulation 8 of the Road Vehicles (Construction and Use)
Regulations 1986 creates the maximum permitted overall width of
vehicles.
A
motor vehicle -
maximum width 2.55 metres.
A trailer drawn by a
motor vehicle having a maximum gross
weight exceeding 3500 kg - maximum width 2.55
metres.
Regulations 100(2) and 100(3) and Section 40A overide the overhang
legislation, this means that even if your canoe does not overhang at all it
could still be illegal.
If you put a canoe or canoes on the roof of your vehilce
and strap them on corectly, how does it look?
If you stand back and think, "*******"!
then it probably is not safe or legal. If on the other hand you think "That's
ok", then it probably is.
Remember there is more at stake than damage to your
canoe.
After all
we are all sensible people - aren't we?
Hope this
helps,
The Viking
