Hi there, I'm looking to build a new trailer. I would like to know what is the difference between the angles of cross membe. Here is a photo of a 39 cigarette with no cross member angle such a reason for it? best loading?

I have never had a tailor-made trailer for my boat I am tired of fighting for the embarkation of the boats.

If you dont run the V shape X members the boat has to set so much higher, you can see in my pic, and the trailer will need to go into the water further for loading and unloading

I understand, I was wondering why he is doing this if he had any advantage

the only advantage I see is more ground clearance

It's all going to depend on the ramp. Having the boat sit that high is going to require a "perfect" long ramp, at just the right angle; with no water height fluctuations. That's going to take a lot of water to get that boat off the trailer. And a step-bottom boat is even worse, as you have to have enough water at just the right ramp angle to get the boat to float over the steps. A straight bottom boat would be easier to work with on such.

Now, too deep of a "vee" in the trailer cross members can be an issue too, as it can hang up on pavement and ramp transitions. Take a look at how Myco and Evolution are now building their trailers. They have the "vee" in the cross members, but they lop off the low dragging section, and reinforce it.
