Replace bunk boards for CV-23 trailer

[dallasbadboy]

I've rescued a Glasstron Carlson CV-23 that has been sitting in a field for a few years. the bunkboards are rotten and the brackets are VERY rusted. I've seen some really good ideas on how to jack the boat to replace on land but need some help with figuring out the best material and the correct brackets to replace the old with. Thanks to this forum I now am aware of issues using galvanized brackets with PT wood and was thinking about using the new composit lumber. Does anyone have any recomendations on this?

There's no point in using the composite lumber. PT Wood with SS bolts and galvanized brackets will last decades under normal use. I would consider just relocating the welded brackets you have on that trailer so that you could just bolt the board to it without the bracket on top of it. Just an inch or so would align the bracket with the hull strake and allow the board to rest on the hull correctly.

cutting and welding is beyond my capabilities and thx for the input on composite material.

+1 on the composite materials. When used on a deck they usually recommend 12" centers instead of 16". PT is a much better option simply because they're stronger.

I've replaced bunks while the boat is beached on my old CVX-18 trailer. Just have them pre-covered. Just need a cordless drill for the pilot holes, a ratchet and socket and new lag bolts. Sounds like you'll have to replace the mounting brackets as well.

Wow, someone sure has that rigged horribly! I wouldn't trailer it much like that. Those brackets really do need to be cut and re-welded in the correct position.

I have just finished doing to my trailer what you need to do and believe me you need to do it right. Who ever rigged your trailer had no idea what they were doing! I would contact a local area trailer manufacture/dealer and buy bolt-on galvanized hardware to go on your cross beams (from the pictures it looks like 3"x3"), they might even sell you the proper carpet that is cut to wrap a 2"x6" the length you need. Buy the lumber at your local lumber store (cheaper) and you don't need composite, just use the cleanest and straightest 2"x6" you can pick. You don't need PT wood as they never really sit in water for any length of time to rot for many years to come. That's your choice. As far as the existing bracket grind it off, if you don't have a grinder, rent one.

Thanks for the replies. Looks like I'll be using my Bayliner for the rest of this season.

After thinking about the options I'm attacking this in two phases as I can't see any way to do this correctly and safely in my driveway with the boat on the trailer and there is no way I'm going to tow it as is. I had no choice but to tow it from the field it was in to the motor rebuild shop (advantage motor works Mansfield Ohio) then to a close by lake for engine testing (which is where I saw how bad the bunk boards actually were) then to my home.

First - I'm going to replace the boards as the struts/supports are digging into the hull and then over the winter/early spring I'll have a professional cut and re-weld the struts/support in their correct position. I've completed the port side and will work on the starboard side when I get back from vacation. All I have to say is WOW - stainless steel anything is expensive!!
