trailer bunk boards

[75starflight]

what boards are you all using for bunks on your trailers?  I am getting ready to put the trailer back under the CVZ-18(yes I still have it) so it can be moved if needed. And Phoenix is also getting a different trailer put under her.

Is the preference standard construction lumber or can I use green treated? The reason I ask on the green treated is I have a few extra 2x6s laying around after a project.  Also, if I use the standard construction lumber would it be wise to coat it in acetone and resin mix before wrapping it in carpet?

I've used both, they both rot equally well.  Standard construction boards can last 3-5 years, treated a bit longer.   The real difference comes from the carpet, use a poly, Indoor/outdoor type that doesn't hold water.  Pontoon carpet I've been happy with.   You could try to resin seal or Thompson's stuff, but in the end it seems the screw points provide the channel and rot the connection out.   Curious, does this mean the cvz project is starting?

Hopefully starting back up on it.

I use treated wood, then put carpet on with contact cement top & sides only. I only wrap enough carpet to underneath so I can get the stainless staples in, basically leaving most of the underside free to dry quicker.  Been doing all my trailers this way, I guess since Julius and those boards are still good (maybe close to 10 years now?).

How do you guys drill for the bolts and what kind of bolts do you use? And they are put in before the carpet right?

I wrap and staple carpet to the bunk boards, then use 1/4" galvanized lag screws to attach them to the mounts.

I've been drilling the boards and using 1/4" galvanized carriage bolts, tightened enough to sink bolt heads away from surface and using either lock washers or lock nuts. Then I'll use contact cement to seal up top of bolts and install carpet.

This is my preference as well

Thanks Guys. How about the fender protection on the insides?

I used to bolt that connection, but shifted away after having to cut the bunks off several times.  Maybe it was cheap stainless? Or disimilar metals, but the nut/bolt connection would corrode.

Ok so are the center bunks 2 x 6 and the outers 2 x 4" Looking at my boat on the trailer, the two center ones sure lend to having a 2x6 down there.

If you have room between the chines, go big!  I'm using 2x6s where I can.  Here's a before and after of my latest redo on the 16.  I know it's a bit overkill, but...

Don't think there is such a thing as "Bottom support overkill" Mark ..
