How to make new trailer bunks?

[cantstopgrandma]

The last time i redid my bunks on my trailer, i used regular pine 2x4s and bought some UHMW PE (ultra high melecular weight polyethylene) and capped them with that. The 2x4s haven't even changed color because they only get wet when launching or loading (its been a couple years now i believe maybe longer). They are under the boat so they have tons of time to dry out and stay that way between trips, and no carpet to hold the moisture on them. I just drilled and counter sunk some stainless screws into them to hold them to the bunks. My boat slides off the trailer like its on rollers, and now when i drive onto the trailer, if the ramp is steep i have to keep it in gear and running to keep from sliding back off the trailer.

If interested, i bought my UHMW PE from www.usplastics.com. I bought 10' of the 1/2" thick x 1.5" wide, and they cut it in half for me (i needed 2-5ft pieces), which saved me some shipping. This stuff is easy to cut, drill, and shape if needed.

I thought about using plastic decking boards, but they are so flexible that i was worried they wouldn't hold up, or would flex so much they wouldn't support the boat.

There's a thread on the forum here somewhere where i discussed this also.

Cantstopgramdma has it right. I have Ultimate bunk boards on my big boat. The composite boards are more flexible than I had figured. I actually had to add another crossmember to keep them from sagging. They scratch alot more paint off my boat than the ones I made from UHMW on my jon boat. I won't ever own another boat without wood/UHMW bunks again. The wood will last ALOT longer if it's not covered in carpet, and it also offers a little cushion for the boat. Straight composite has NO give to it. Definitely the best way to do it as far as I'm concerned. Once you build a set like this you'll never do it any other way.
