Default replacing wood bunks with synthetic ideas?

Im looking to replace the main bunks on my trailer for my 176 deep V aluminum boat. Right now it has 2x4 wood bunks (2). I am looking for information on synthetic boards for replacing the wooden ones and also if I should go to 2x6 boards? If anyone has synthetic boards and would like to tell me as well how they are working out that would be great!

Thanks for the insight!

I replaced my carpeted bunks with these https://www.ultimatebunkboards.com/ about 4 years ago & they work well. Yes, they will scratch the bottom paint but no more than carpet that has dirt/gravel in it. When loading/unloading treat them like a roller trailer, they are slick. Add a Drotto (https://drottoboatlatchsystems.com) bow latch & you're set!

X2 on the ultimate bunk boards. 6 years and with a 2 speed winch all is good. Best money I spent!

A couple of years ago I replaced my rotted carpeted wood bunks with treated 2x4s covered with a strip of starboard (plastic). The inspectors at the boat ramp approve of the non carpet bunks. Don't unhook the safety chain until your are backed into the water. One thing I need to do is to slot the holes in the starboard, because when the trailer sits in the hot sun they buckle up but they come right back when backed into the water. 1900 Pro-v on a prestige dual axle trailer. I got the idea from someone on Walleye Central.

Same here, replaced rotting bunks on my shorelander trailer with 2x4 cedar and screwed 3/4" starboard on top,
Cedar is much more water rot resistant than original untreated pine covered with carpet,
I left it untreated and open on the sides and bottom, that way it breaths and dry out quick,
It has been a few years and no problem,
Just treat it like a roller trailer when launching and retrieving the boat

Bob you should read the max span for those 2x4's before using them.

Last time the bunks were replaced, I used 3x6 cedar with nothing on the wood. All of the mounting bolts were recessed, so that there was nothing above the wood to scratch the hull.
No finish on the cedar since it ages grecefully. Little to no rot on the cedar as well.

Upsize the lumber size since cedar is a softer wood and needs to be larger for similar load carrying ability.

Also, I made walk boards out of cedar as well that work fine.

Be safe

You'll be making a huge mistake. Trex is not rated to span any more than 24". I don't know of any composite decking that is rated to span any more than 24". Composite decking has no structural value, whereas dimensional lumber does. A 2x6 can carry a load. My boat is far to important to me to trust the wrong product.
