There are actually some products on the market for this. I used Amazing Goop Coat-It on the bottom of my little aluminum skiff. I was a little unsure about it, but was pleased with the results. The only thing I could compare it to, it was like painting a slightly flexible layer of JB Weld on the bottom. It also has kevlar in it. Very messy to work with, but cool stuff.

Here is the recommended uses, from the manufacturers website

What is Coat-It and what is it used for?
Coat-It is a 100% solids waterproof graphite black epoxy sealer and coating. Its original application is an armor plating type high build coating for the bottom of fishing boats, kayaks and canoes. Cured Coat-It creates slip and lubricity when the boat comes into contact with rocks, gravel or shrubs as well as protects boats from damage.

Here's how it came out on my boat- A constant work in progress





That being said, I'll wait a bit to try it on my yak- Give it a field test on the boat first. If I had a less expensive yak I wouldn't hesitate to try it, but this stuff was so sticky I don't think you would get it off once you started. I do think it would work though.
