Although Vancouver Island hasn't had many storms this winter, nor the
rainfall we so desperately needed, we have had a few intense systems
move through. I wasn't going to mention the following incident, but all
the recent talk about dangerous amounts of water and cockpit volume has
drawn me out.

Last week we had a squall blast through, but it was later in the
evening. Wild wind and rainfall was prodigious, but short lived. My
kayak's cockpit almost completely filled with water -- and I wasn't even
sea kayaking.

Actually, I had put the kayak away on the exterior kayak rack, high
alaong the fence line, after getting home late from some normal gale
paddling. I was tired, did not place the cockpit cover on, and did not
invert the kayak over onto the padded racks as I normally would have.
So, it filled with water and came crashing down in the night with a huge
thud. The extra reinforcing proved beneficial once again. And, oh yeah,
my heavy Nordkapp, even heavier with the added water, narrowly missed my
wife's budding Tulips below. It was a very close call indeed.

Glad the boat and tulips came out alright.  Here in Western North Carolina
we had a late season winter storm blow through last week.  There is a lake
near my house that has a small boat storage area with canoes and kayaks of
all flavors stored inverted and locked on to a wooden racks.  The boats are
stored 3 high and 2 wide on horizontal 2X4 crosspieces that are attached to
a center 4x4 post.  The wind was fierce during the storm and the tops of
several of the racks were broken with the boats twisting and falling with
one end on the ground, hull down, with the other end still locked up at the
crosspiece.  They stayed out like that until the next day's snow which
obviously filled and weighted the boats causing the whole structure to fall.

What's the point of this story? Not much, just a similar one to Doug's,
although I do have a question.  Say a kayak is stored with it's cockpit open
and up and somehow manages to become filled with water, which then
subsequently freezes...would the expanding ice be enough to break a
composite boat or even a plastic boat?  Where would the boat break if it
did?

Ironic, isn't it Doug?  Your greatest danger yet w/sea kayak was
averted by sheer luck - not by any of your skill and lovely redundant
safety features.  Perhaps *they* will come in handy on another day.

Its amazing how many people travel and stay over night with their kayaks
right way up and uncovered on their roof racks. I have always wondered what
happens if a storm hits.  Cockpits would hold between 80 - 100 litres of
water, which added to the weight of the kayak itself would equal  120 + kg .
Not only would it effect the vehicles handling, but how would they get it
down without bailing first? It could be a bit embarrassing being seen
sitting in your kayak on top of a car in front of a motel using a hand pump!

Cheers

Quite often.

>Cockpits would hold between 80 - 100 litres of water,

So how many inches of rain fall in 12 hours? Divide that by 1/3 (cockpit 
opening vs cockpit floor area). Now what volume?

>  which added to the weight of the kayak itself would equal  120 + kg .

Doing a visual (mental) image of a bunch of wine cask liners in a cockpit 
I'd say 24 kg max.

>Not only would it effect the vehicles handling,

Less than the different between and couple of plastic kayaks and a couple 
of wooden ones.

So there we were in the main street of Warkworth and I'm pumping out the 
cockpits, kayaks on the roof of the van and an Asian girl (must be a 
tourist) is standing open mouthed in amazement - my partner is nearly 
rolling on the ground laughing (at the spectator's expression).

There was a thread a year or so ago (rec.boats.paddle) about kayaks filling 
their cockpits with water over night and splitting from the weight - if my 
kayaks (wooden) couldn't stand that weight I wouldn't paddle them - OK 
fibreglass (except Doug's) are fragile but still not that weak. As above, 
about 3 foot of rain over night to fill a cockpit. I'd have the boats off 
the roof rack and be paddling from the flood by then.

SNIP: It could be a bit embarrassing being seen sitting in your kayak on top
of a car in front of a motel using a hand pump!

Alas, I wasn't there to witness the event myself, but I heard of two guys
leaving a camping, one driving while the other was sitting on top of the
car, in his kayak, paddling, steering and bracing in the air, following the
movements of the car. Although he was wearing a wetsuit, sprayskirt, PFD and
helmet, the police considered the situation "unsafe" and ordered him down. A
footpump and some water would have added greatly to the show.

John Dowd describes such an incident in his book:  

"I have personally broken a kayak from whiplash when I drove over a curb, not
realizing that an inch of rain had accumulated in the bilges overnight."  [Sea
Kayaking, 1988 edition, page 75]

Had to be much less than the 120 kg associated with a full yak.

I'm now being accused of having bungs in the bottom (!!??), however I was 
looking a  DRR last week and there was a neat threaded hole in the side 
which went to a plastic pipe. The hole was supposed to be below the water 
line though the owner admitted he actually had to lean the kayak a little 
to get it under.

Drinking water = weight.

So, paddling (racing) in a river or lake why not drink it? Remember this is 
(supposed to be) a clean green country.
