I have carpet coated wood bunks on my trailer.
Judah, the trailer came with guide posts, but attaching them is tricky. Also the posts take up more space around the boat, I have little space to walk around it where it is. Other than that I'm just a minimalist.
Your not most likely going out on big wind days. Your boat is light and has little windage as it's low profile.
If you go out out on a day that it's blowin, just walk the boat on and off the trailer.
