Launched the boat on Saturday morning and realized that the bunks on the trailer are falling apart. Got the boat trailered on Sunday barely. Now i need to replace the 2x4's next week end. The question I have is on a 25' boat trailer what length of boards do they use. I can not imagine that it is a 24' 2x4. The boards are attached with lag screws. There is no logical place I can see that you would splice shorter pieces. I want to take the pieces down with me. Need help. Don't want to get there Saturday and remove everything to see how it was put together and not have what I need on hand.
