: Great website. I developed a method of doing the final foam carving to get
: the perfect butt imprint. I had carved a foam seat the best I could by
: sitting, feeling and looking at the foam for any telltale imprint or
: pressure marks. When I tried it out paddling, my feet fell to sleep.

: I sat the kayak on my living room carpet and stuffed rolled towels on each
: side to keep the kayak's vertical axis vertical when I sat in it. I then
: cut a piece of 6-mil plastic to the width of the seat and twice its
: length. I folded the plastic in half lengthwise and taped the two sides
: with clear plastic packing tape to make a pouch and then put a new all
: bees-wax, toilet seal inside, pressed the air out and taped the last side
: closed. The taping was done with care to avoid wrinkles and to get a leak
: tight seal all around. I placed the wax filled pouch into a
: pilot-light-only warm oven for a couple minutes to soften the wax. I put
: foil to from a drip pan on the shelf under the wax filled pouch for
: safety. Wax is a fire hazard so I watched closely, a hair dryer might have
: been safer. As soon as the wax was soft not melted (it turns clear when it
: melts) I rolled the wax out evenly in the pouch with a rollingpin on the
: counter top. After warming the wax again until soft, I placed it on the
: seat of the kayak and sat on it wearing my normal paddling pants. After a
: couple minutes I got out and lifted the pouch out. Holding the pouch up I
: could see through the thin spots where the seat applied the most pressure
: to my buns. Overlaying the pouch back on the seat I noted the pressure
: points on the foam and marked them with a big felt-tipped marker. I took
: the seat outside (I used Velcro with hooks epoxied to the hull and pile
: contact cemented to the foam) and used dragon skin to carve away the
: marks. I put the foam back into the kayak and did another soft wax
: impression, marked and carved. I repeated this until the wax was equal
: thickness over the total impression.

: With this method I discovered the seat shape and angle match my shape when
: sitting in the actual paddling position in my kayak. The final result fits
: like a glove, so to speak, and no more sleepy toes.

Sounds like an interesting method and since it seems to have worked, and you are comfy with it, can you tell me approx. what the seat and backrest angles are? I would like to know at what angles ( from horizontal and/or vertical )your seat fits properly and comfortably. Thanks
