re: Pvc boards on top of bunk boards

When i had my world cat the front half of the bunks had pvc. Made coming on and off the trailer much easier. But on a steep launch i would have to keep the power going till it was hooked and winched tight if not i would slide back into the water. Made solo retrieval a challenge. My brother has gator glide and synthetic bunks on his surface drive boat and had to install rear cleats on the side guides so he can tie off after powering up if not it just slides back off.
