Two questions:

1) I have been paddling a variety of different sea kayaks over the last
year, and because of that used a suite of different paddles. Some paddles
have a strange feel in the water: as if you pull your hands through sand.
It seems as if I pull a vacuum behind the blade, and the collapsing of the
vacuum bubbles gives this strange feel, and give me the idea that I am not
transfering my power efficently through the paddle onto the water. Some
paddles do this, others don't (independent on material, quality or price).
Any ideas on why? Is this poor design, or is it my technique? Also, some
paddles are very noisy in the upstroke out of the water, very splashy (yes,
I know what is up and down :-), while others are very quiet. Curious enough
the paddle I like best is a cheap, aluminum/plastic thing with broad
blades. Might be related to my 6'2". I prefer to make long, powerfull
strokes instead of multiple shorter ones.

2) Yesterday I did a great trip to Anclote Keys (near Tampa, FL) in an
Eddyline Falcon 18. Such a nice boat! But, as I had noticed before in this
boat, my legs and feet start getting numb after an hour. I have fiddled
around with the footpegs, but that doesn't seem to help. I guess there is
something in the seat design that pinches a nerve or artery, because I
never have this problem in the Dagger Magellans I frequently use. Yesterday
I tried sitting on a towel(couldn't find a piece of foam), to modify the
seat mold. But that didn't help either; today my legs and feet still feel a
little numb. Any suggestions for dealing with this problem?

Do the sides of the seat turn up pressing against the sides of the buttocks
and legs? If so that's the problem, where the preasure is. I've sat in what
appeared to be comfortable seats and then found they caused numbing.

If the seat is convex (ridge running fore and aft) rather than concave and
if it is tilted up at the front and if it is long enough, then you might
have comfort. Side pads near the top of the pelvis will give lateral support.

Kayaks should not be sold with seats. These should be bought as a separate
item (included in the cost if that's what you want) and chosen to suit each
customer.

1)  I would start by having someone assess my forward stroke form to ensure
proper technique.   This will lead into being able to evaluate the paddle.

2) I have seen some people place a paddle float under their thighs to elevate
the angle.  This may help aleviate the numbness.

Hope some of this helps. I'm sure others will be providing suggestions.

Alex has already chimed in with the ultimate solution:  make a seat that fits
you.  This will entail significant outfitting, and is best done by fitting a
minicell seat (custom carved to fit *your* tush) in lieu of the stock seat.

If the Falcon 18 you paddled has the stock Eddyline plastic seat, I suspect the
front edge of the seat comes up too far, shutting off blood flow on the bottom
side of your thighs.  If you own the boat, you can remove the seat and cant it
forward a little by removing some of the foam on the underside of the front. 
Not for the faint-hearted!

True, but the next best solution might be some sort of thin pad.  Someone
makes a thin gel-filled seat pad that might help.  Alternatively, you might
try a minimally-inflated seat-sized Therma-Rest pad on the seat.
