I posted this once before, but can't resist joining the throng:

I carry a 21' tandem on a Hyunday Elantra with no bow or stern lines
with not concerns for it coming off at Interstate speeds.  How-

1)  The Elantra is a wagon, with factory side rails, to which to clamp
the Thule system.  I bet the whole shebang that flew off that one car
was a door frame clamp on model.

2)  I use Thule saddles, only.  No pads, no Yakima hully rolles - the
saddles, properly spaced, are key.

3)  A good tight tie-down with good straps and the end of the strap tied
off for secondary security it doesn't come loose.  The strap is looped
around the bar on each side of the boat outside the saddle - I do not
use the slot in the saddle.

My point is not that bow and stern lines are a bad thing, but alternate
arrangements can be safe.  My 18' single is rock solid in the saddles
(doesn't even waver) and the tandem only moves slightly in the toughest
conditions (strong cross-wind gust, tractor-trailor flying by too close,
crossing a big bridge in wind).

Regards,
Ellis

I tie down hundreds of boats every summer and I agree that most boats can 
be safely held in place using saddles and two good camstraps.  However, 
it's important to note that Yakima (I'm not sure about Thule) offers 
terrific assistance to their rack owners if something happens to the cargo 
while driving.  Specifically for boats, Yakima goes to great measures to 
help you if your boat launches due to the rack failing, but only if you use 
proper bow and stern lines.  In my opinion, the two minutes it takes to tie 
the bow and stern lines is worth the peace of mind just in case something 
fails.  I've seen it happen and it ain't pretty.

And I bet the guy who designed the little clips that hold your factory rack 
to your Hyundai did so with the full and clear understanding that you were 
going to put the Queen Mary on your roof, Ellis.  

Yak and Thule make some really great rigs for factory racks, and the fit is 
solid on most factory racks.  Problem is, a lot of factory racks are pretty 
low-tech on installation hardware.  Don't know that I'd ever want to trust a 
rack on a Hyundai --- or on a Mercedes or an Audi ---  without tiedowns.

subject: [Paddlewise] rackets / Lines / general problems
Date: Wed, 18 Apr 2001 08:56:13 +0200
Jo, I got some experiences with rackets, too.

We got a Thule racket for our VW Passat. A strong system with claws special
designed for this roof. There are little triangulars behind the upper sides
of the claws. They hold the claws outside the basic foot so the claws fits
the car roof flat and 100 per cent.
Some time ago we lost one of these triangulars and it seems to be no
problem. But normally I secure all boats by a front line to cars recovery
claw.
About 2 weeks ago I place one heavy Aleut Sea II, an old foldable double and
a heavy K1 on the racket, so it was "full", donīt ask for the weight...

This time I hadnīt towed a front line and after 2 miles something was
scratching on the roof. What had happened?
No front line, the boats bob up and down and because of the missing
triangular (front racket) the claw flips away from the roof! Oh oh!
I refit the claw but then I saw the problem. Without that triangular the
claw couldnīt be flat to the roof. I īve had to find a new triangular! 60s
thinking, then I take some tape and a little peace of close cell  foam,
press it and put tape around, press it behind the claw and fit it. Ready!
The foam function as this little unconspicuous triangular.


2nd incident happened about 7 years ago. The car from a club member got an
integrated deck rail (for rackets) and there have been 2 K1 on the racket.
After half an hour the boats began to wave up and down. We stop, the front
racket sprang out the rail because the rail was damaged. I was lucky,
because I had fixed a front line down to the car. But we could do what we
want, without special tools we couldnīt repair the deck rail. So I take a
long webbing rope, put around the racket on each side and close it INSIDE
the car, ready. No the racket was bombproof, but we had to pay attention to
our heads because of the webbing rope running through the car above our
heads.


These and other incidents are the reason I always got more "unneeded"
material with me, than other people. If something happens, I got a solution.

I remember this remarkable day when we were on a 2 week paddling trip from
school in Austria and Slowenia. My teacher had damaged his thumpkin nail and
ask for "a little piece of tape". I open my waterproof barrel, and grap down
to the ground and ask him "Which colour?" ...
You must have seen his face!
Anytime, if someone needs something their first way is me.  Otherwise I
always got the heaviest boats and bags.

>Best way to avoid problems is to shock the potential problem with a
solution, so the problem looks for another victim.< :-))))


whish you all the best
Jochen

It seems that quite a lot of PaddleWisers have experienced problems with
boats on top of their cars. Although they describe minor problems, that only
required pulling over and fixing something, try for a moment to imagine the
worst-case scenario: A kayak that gets blown off your roof on the highway,
sails across to the other side and hits the driver off a loaded schoolbus...
Well, don't let me spoil your sleep tonight, imagine the rest for yourself.

In my business, the oil business, we believe in "redundancy", a principle
that I also use when tying a kayak to a car. The principle is: ANY part of
the construction must be allowed to fail without everything collapsing.

The normal way of tying a kayak to a car in Holland is fixing a trailer onto
your roof, then fixing two kayak holders to the trailer, then fixing the
kayak to the holders using ropes. In this way, whatever part breaks, your
kayak looses one of its two supports, gives a stress on the remaining
support that it is not designed for, and in a matter of minutes or seconds
your kayak is gone.

A bow line and a stern line make the whole construction redundant: Whatever
part fails, there is always a part to back it up. If the bowline fails the
trailer is the backup, if the trailer fails the bowline is the backup.

As we all know, the driving part is the most dangerous part of a day of
kayakking. Be safe!

Actually, tying boats to a car should be part of every safety course in
kayakking. Sometimes I am amazed by the knots and constructions people dare
to use.

Niels. (who only uses bowlines when he feels like it. I have total
confidence in my own knots and technical insight.)

        I recollect a survey done some years ago, possibly by an insurance
organization, that said that nearly 80% of all damage done to boats is done
on land, not water.  Mostly collisions involving trailers but also cartopped
boats going astray.
        Suppose that you rear-end someone.  Stop fast enough and your
kayak's inertia will rip the racks off forward and spear into the car you
just hit....  That could be very bad. Also, you've probably damaged the
mounting area of the racks as well.
        The rear tiedown, at the very least, should be there to help prevent
this.  It could help restrain the boat and racks...  I know of one person
who ties another rear rope to the racks to be sure of this.
        For those reasons, my tiedown ropes are not minimal.  I use 6 mm
Prusik line which tests well over 2000 lbs.

That line to the rear rack is a good idea, Joe.  I had not thought of that.

It is perhaps better insurance than the rear tiedown, because if the bow of
your yak extends past the front end of your vehicle, the _front_ tiedown should
be the first to come into play in keeping the yak from sliding forward,
inasmuch as the stern of the yak invariably is rearward of the rear bumper ...
at least for sedans.

On my Toyota canopy-equipped PU, I mount the forward rack over the center of
the cab and the rear rack at the rear of the canopy.  This puts the bow
rearward of my front bumper, so neither tiedown would prevent the yak from
sliding forward some.  Either tiedown would keep the yak near my vehicle, and
probably prevent a spearing of the vehicle ahead of me.

Your buddy's rear rack backup line would be better insurance in my situation. 
Thanks for passing on the tip.

Niels, I don't mean to be rude or anything, but in Canada, we usually
tow our trailers behind our vehicles, not fix them to the roofs of our
vehicles. Is this some kind of law there, or is it just because Holland
is so small that the extra vehicle length with trailer behind would take
up to much valuable space? 8-)

On a more serious note, I've just installed a Class 3 trailer hitch on
my van, so can now tow items. Does anyone have any good links to
trailers that can carry kayaks/canoes? I'm looking for something that
converts to a tent trailer and/or gear hauler, as opposed to a "kayak
school multiple kayak trailer" one sometimes sees at symposiums and
classes, etc. I was wanting to build/modify my own trailer.

I have traveled a million km on German highways, and during 
vacation time I shared the road with travelers from Holland 
migrating South.  Apart from the yellow licence plate these guys 
were easy to tell by the camping trailers they had in tow.  
You see, the spot behind the car is usually already taken, thats 
the reason to come up with another idea since two trailers behind 
one vehicle are not allowed.   But I agree a roof rack should do the 
job.
