Thank you! That is the best explanation I have seen on how/why to tie a boat
down. I have seen some nightmares out on the road. --- Some of them were
mine - I have worked it out to more or less what you describe, but it took
many tries and stops along the road to fix loose ropes to work out what you
have explained well in a few short posts..

I'm trying to figure out why this should be so.

Hi Mike. When the car is going straight with a direct headwind, it *is*
irrelevant. But having the boat far to the rear, as many people tend to do
instinctively when they center it over the cockpit of the car, gives you a
'sway' if you have a sidewind, or if you get a blast from a passing
tractor-trailer. If the canoe is centered, you only get a lean. It also
distributes the weight evenly on the car: otherwise you ride like you have
a
loaded rear end.


**This
line should be hauled tight enough to lift the stern of the canoe up
off
the
back roof rack about 6 inches.**

4) Go around back and tie a line from the back of the canoe down to the
center of the rear bumper. Haul down on this line. This should pull the
canoe back down onto the rear roof rack, and provide enough downward
force
to 'lock it down' onto the roof racks, and 'lock down' the roof racks
onto
the roof of your car.

The results of this arbitrary 6" lift will be highly dependent on the
amount
of stretch in the line, on the distance between the rack crossbars and
on
the type of canoe you're tying down. Stiff lines on a light canoe
mounted
on
closely spaced crossbars could break the hull while soft lines on a WW
canoe
with widely spaced bars may have little effect.

Yes, you are completely correct. 6" is an approximation of what I used
with
my boat, but your response shows that you perceive the situation clearly.
I
should have said 'enough tension to raise the stern of the canoe a small
amount, so that when you tie down the stern, it tightens the bow line
significantly."

Just for reference, here are a few pics of how NOT to load a canoe on a car.
These folks all centered their boats over the cockpit of the car, or
centered them over the roofracks. You can see that it moves the boat way to
the rear, makes for a very unaerodynamic load, and leaves both endlines
running forward; perfect set-up for the canoe coming loose when the driver
puts on the brakes.

Conversely, here is a pic of a canoe properly centered over the wheelbase of
the vehicle. These will ride more stably, not cause a sway if there is a
sidewind, and most importantly, the endlines are pulling equally in opposite
directions so the boat will not shift around.

Gotcha.

Ditto - but in winter with many cars, that's a good thing. 'Course paddling
when there's snow and ice is only for us crazy folk.

If you drive around with the roof rack or anything else on the top of the
car you'll use more fuel. I even keep the boat tied low to the roof to
reduce drag. My roof rack consists of two pieces of rolled up carpet. In
this case the strap actually holds the boat to the car, not to the rack.

I would not pull the front of the canoe down 6" and tie it off as described.
It might crack or distort some canoes. I'd just make sure it was tied on
snug.

I use only the straps to drive along residential streets over to the
river, 1 mile away, speed limit 35 mph, but tie the ends down when going
further and faster.

When tying down the ends each is tied with a 12 foot length of 1//4 inch
rope. One end is tied to one end of the bumper (actually to the ring under
the bumper they used to tie the car down on the boat from Asia where it
was made) with a bowline knot, passed up and through the ring on the bow
of the boat, then down to the other bumper ring where it is snugged up
with a trucker's hitch. Same on the back. When the boat comes off the roof
of the car the two lines are tied to the ends as painters.

There are photos on my website under "Boats" (Dogskiff, Loonie, Delta).

Our van did not come with a roof rack, so we had one installed. When not in
use, everything comes off except for four small brackets. Not only does it
mean no wasted fuel, but you don't have the various noises resulting from
the wind resisitance.

If you're driving in Ontario, then that's in violation of the highway code.
If a load extends beyond the vehicle, you have to tie down the ends.

I found that, unless I actually tied off at the bow ring of the boat, the
boat was free to slide back and forth along the rope. I tie off at the bow
ring with a bowline, run the line down to one end of the bumper, through
that tie down point, across to the other end, then back up to the bow.

And then when you tie the stern probably the best way is with a
trucker's hitch. The coolest knot ever. Be careful though, you can
break stuff with a trucker's hitch by tightening it too much. It's like
using a pulley.

Correctamundo on all four points. :-)

I can speak from experience. It was only a three hour cruise... er make
that a three minute transport from shore to storage. I was tired and
only tied on with lines over the hull. At first stop, I was horrified
to see my kayak launch out over the hood of my van, like a bar of soap
coming out of your wet hands.

The Overflow luckily is used, plenty of scratches, and 40 ft of sliding
on asphalt did not hurt it any. The thought of causing a serious
accident did get my attention! However the worst was having to get out
and pickup the pieces and put it all back together, with all those
other folks pointing their finger, and gauking at me! They had a good
laugh!

Be sure and use the bow and stern lines, :-() Sheepish me, TnT
