I fish mostly in the ocean where landings are not always as soft as I would like them to be.
What I did for my previous kayaks, and what I'm going to do for my brand new PA 120 360 - is to make some nice little kevlar fiberglass keel protector for the nose of the kayak.
All you need is some unwoven kevlar fabric (you can buy it by square foot on the eBay) and a can of fiberglass resin. The complete cost of the materials is about $40. Also you will need a pair of sharp heavy duty scissors to cut a custom strip of kevlar fabric (it's really hard to cut!).
I usually cut the strip in the shape of a very sharp angle triangle 24" long, 6-8" wide at the bottom and 3-4" wide at the top. All corners are rounded.
1) Sand the area you are going to apply the protector with some coarse sandpaper.
2) Protect the neighboring area of the hull from overspills (I use self-stick carpet protector film and masking tape, it works perfectly)
3) wet the area with FG resin
4) apply the pre-cut kevlar strip
5) use chip brush to heavily saturate kevlar with resin.
6) let it half-harden (15 minutes or so)
7) apply another 2-3 layers of resin
let it harden completely
9) sand it if needed.
The kill protector will stay in place and will protect the soft polyethylene of your kayak's nose for at least a year. To maintain and repair it, you simply need to add a couple of layers of resin and, if it got seriously worn, more kevlar.
