Here's an easy way to make eyebolts. It requires some wire of the appropriate diameter, a vise (Panavise or similar), a pair of wirecutters, a candle, and some small drill bits. If you have all the tools, the eyebolts themselves will cost less than a penny apiece.
I like brass wire (such as is sold by K&S in most hobby shops, and Detail Associates in shops catering to model railroaders) for this purpose. The diameter should vary according to the size of the eyebolt; .010" and .20" will probably serve most purposes. If you don't have convenient access to a source for brass wire, copper will work fine. Get hold of a piece of multi-strand electrical wire, strip off the insulation, and separate the individual strands.
The problem with brass wire is that it's a little too stiff to bend easily into the necessary tight loop. So heat it over a candle flame until it's red (ten seconds or so), then let it cool.
Pick a drill bit whose diameter is the same as you'd like the inside of the eye to be, and clamp said bit in the vise. The bit serves as a "mandrel" for making the eyebolts. Just loop the wire around the bit and give the wire three or four tight twists, so it forms a tight "pigtail." When done, move half and inch or so down the wire and repeat. When you've used up all the wire, cut the individual eyebolts off. (You may want to dunk them into some sort of chemical blackener first.) Drill holes in the deck to accommodate the "pigtails," glue the eyebolts in place with superglue, and you're in business.
It may take a little practice, but you'll quickly be cranking out eyebolts at a rate of at least one per minute.
One big advantage of this system: unless you yank the line hard enough that the wire actually breaks (unlikely; the line would break first), the eyebolt will never come open. The only danger is that it will pull loose from its hole. If you plan far enough ahead you can eliminate even that risk, by leaving the ends of the "pigtail" free and bending them underneath the deck.
Hope this helps. It's easy.
