I started making the deck fittings using polypropylene webbing. I'm melting the ends to form loops with small square flanges formed using a mold. Linked pictures show how I did it. The idea came from Joe Greely at Redfish Kayaks. The loop will be passed through small slits cut into the deck. A bead of RTV around the flange will ensure a watertight seal.

I also laid up some blanks to use as fittings. I did one flat for webbing and a round one for deck lines or bungees. The tooling parts were formed from blocks of wood and covered either with packing tape or saran wrap was used as a release film. Here are some pictures of the process.

Here is a "re-enactment" of the sandwich after considerable triming and release from the mold.

And the finished product. These will be cut into shorter pieces and glued to the deck or hull.
