Tom,

Hi. It was good meeting you over the weekend.

A sea sock is like a large condom that you place around the coaming of
your kayak and whose material forms a pocket or sock in which you sit. 
It extends well forward under the deck and should accomodate even the
tallest paddler.

Its purpose is to keep water from filling the cockpit.  Also dirt.  A
sea sock works well for folding kayaks that, by their very nature, lack
bulkheads.  A sea sock limits the amount of water that needs to be
pumped out in the event of a capsize and keeps sand and gravel from
getting to the inside of the boat where it may rub at the deck and hull.

Feathercraft provides sea socks with all their models as standard
equipment.  I never use one and therefore I did not have one on my boat
when we were paddling at West Point.  If I had, you would not have been
asking this question.  I don't use one because I like to get at gear
inside the boat and the sea sock complicates such access.

I am not sure you could get one to work well on your plastic kayak.  The
cockpit coaming is probably too rounded to be able to accept both a sea
sock and your spray skirt.  Fiberglass boats have sharper edged coamings
and deeper grooves than do plastic boats and the combo of sea sock and
skirt tends to stay on better in them.  This is also true of the
Feathercrafts folding kayaks all of which have fiberglass coamings
absolutely like those on fiberglass boats with the exception of the
inset groove to which part of the folding kayak skin goes.

Several companies sell sea socks on the after market.  SEDA comes
immediately to mind but I am sure there are others.


best,

ralph

Hi all,

Here's a quick (regurgitated if you are on the CPA ListServe) answer:

Tom wrote:

Imagine having a mold made of the inside of your cockpit, from the bow
bulkhead back to the stern bulkhead and out to the cockpit coaming
(rim).

Reproduce this mold in heavy gauge waterproof nylon and attach it around
the cockpit coaming as you would a sprayskirt and you have yourself a
sea sock.  In effect, it creates bulkheads for a boat which has none,
making for a much easier dumping of the water from the boat.

The sea sock fits under the sprayskirt around the cockpit coaming, thus
giving a kind of "double seal".

It does not slide out when the water is dumped, but may
get hung up temporarily around the feet during a fast beach exit,
depending how "gummy" your footwear is.

The only real down sides to using a sea sock are that it tends to get
very hot and "clingy" during hot weather paddling, and it does let in up
to a cup of water per hour of rolling or storm paddling (none if the
sprayskirt never touches the water).

I always back up the sea sock with inflated float bags, bow and stern,
for an extra measure of safety.

In addition to us folding boaters whose boats have no bulkheads to
prevent many heavy gallons of water from entering the ends of the boat,
the sea socks are also used by some kayak racers, surf kayakers, and
even a white water boater or two (so I've heard) for basically the same
reasons: to limit water entry into the boat upon wet exiting, and easing
the process of getting the water out of a boat without bulkheads or with
unreliable bulkheads as an added insurance policy.

If the sea sock fits over the same coaming that the sprayskirt is attached
to, what prevents the sea sock from being released when the spray skirt is
released from the coaming?  Especially if the sprayskirt fits tightly and is
a neoprene skirt??

The concept of a sea sock sounds very practical, but the descriptions so far
indicate that the sock *might* pop off when the spray skirt is released -
thereby negating the main reasons for using the sock.

What am I not understanding?

Erik

Again in defense of sea socks which I don't particularly favor for
myself but for which I do see a practical use.

To my knowledge, this has not happened at least with Feathercrafts.  I
have been contact with hundreds of Feathercraft owners who use
sprayskirts over their seasocks on their coamings and this has not
happened.  This goes for the nylon sprayskirts that come with most
models of Feathercrafts and with the optional neoprene ones that come as
standard on the Khatsalano (I think).

It won't or at least hasn't for hundreds of users who I have been in
contact with.  I am not certain however, as I stated earlier that this
would be true of a sea sock used on a plastic boat's round non grippy
coaming in conjunction with a spray skirt.  I am not saying that it
won't work with a plastic boat.  I am saying that I don't really know
but suspect that given the round contuours of plastic boat coamings and
the difficulty they sometimes have in hold even a sprayskirt, it makes
me wonder.

Your undrstanding is fine.  Perhaps the descriptions of the problem hve been
too slim.  In my experience with a nylon SS, the slipperiness is at its
greatest between the sprayskirt and the SS.  The SS does not slide so readily
over the coaming as the skirt slides over the sock.  So I have never had my
sock come loose, even though I have multiple wet exits (in surf practice) which
included loosing the skirt.  Helping, no doubt, is that the sock is held in by
air pressure, which does not apply to the skirt (it does not seal tightly
around my body).

BTW, I share Bob Phillips disgruntlement at the sales pitch Pygmy gives for the
sea sock.  It is a good safety device, but packing from the cockpit is not
wonderful.  Give me hatches on a boat to be used for overnight trips.  That
said, I followed Pygmy's advice and left my Osprey hatchless -- and it works
fine for a day boat, which is my main use of the boat.
