So was I. Still mulling over using trex and then some creative laminating and router work. Once I re-do this trailer I don't want to replace bunk boards or media blast rust again. Pricey: http://www.ultimatebunkboards.com/I was thinking of using a plastic board (similar to Trex material)..... .......Any links to other ideas including info on the Ultimate bunk would be appreciated. Thanks!
How about using 8" then just cutting out the appropriate places to clear the cross members etc. to customize the height. where needed. Or use 8" all the way and raise the bow roller as I and some more did on the last rig I had. A pair of 3" schackle straps painted then placed between the roller bolt and the old roller boat holes worked JUST right.I'm looking for an 8" wide board because I need a taller bunk at the back with a taper toward the front to put the bow back down on the roller. I thought about trying to start at 6" and go shorter from there but that would put the boat too close to the trailer fenders.
I agree with leaving the bottom of the board exposed to aid in drying and plan to do the same. Getting the water off the bunk carpet ASAP should also help the wood to last longer.
My direction also.I'll be using carpet to protect the bottom of the boat but I'm trying to avoid the long-term deterioration of the wood.
