General trailer/bunk/hardware question

[IT54TR4P]

If my trailer is theoretically utilizing the following crossmembers or something similar...

Will my Logic 210CC be properly supported if I follow the recommended 2x6 bunk layout using these brackets...

Things with my Logic are going fine so far, but the fella I bought it from kept it in the water and I will be mainly keeping it on the trailer. The trailer currently only has two vertically mounted 4x6 bunks and I want to get it set up right before any warping starts to happen or transom issues crop up. Mounting the brackets on an angle has me a bit concerned though.

As a Premium Member subscriber you have access to the "Resources" section of the website where you'll find the last approved trailer bunk schematic from Triumph Boats supplied in 2008. You can download that to guide you in your trailer support of the 210/215 Triumph hull. Here is the link: https://www.performanceoutdoors.net/resources/triumph-210-215-trailer-schematic.5/

Hope this helps.

Randy is certainly pointing you in the right direction.
I have a few thing to add.
My 210 has spent about 2 years sitting on a boat lift with only 2 vertical bunks supporting it. They are substantial bunks (2'x12", I think) and of course with them mounted vertically they are very stiff with, no discernible flex. I also made sure to adjust the spacing to fit the hull as well as possible. But, even though this is probably not following the recommended procedures, I have noticed no warping of the hull. I believe the much stiffer orientation (vertical vs horizontal) of the bunks has something to to with this, but at any rate, that is my experience.
Secondly, The links you provided indicate the use of galvanized steel, aluminum and stainless steel for various components of the trailer. I think this would be a big mistake. Using 3 different types of metal with different galvanic potentials is sure to lead to corrosion issues, at least if you use the boat in saltwater. It isn't whether each component is prone to corrode by itself, it is the interaction of the different metals bolted together that will cause a problem.

I was just using the links as examples. All of the components I plan to use are galvanized. It doesn't matter too much though because I do run this boat in freshwater.

That being said, the main cruz of my question is whether swivel top bolster brackets can be mounted to an angled drop center crossmember such that the brackets are not mounted squarely vertically (everything I've read said they need to be). The more searching I do, though, the more I see trailers like this one specifically for Logic/Triumph hulls with the bolster brackets mounted on an angle.

I think I'll be ok to remove the two fixed 6x4 bunks and switch to four/six horizontal 2x6 bunks on swivel brackets according to the recommended layout. Just looking for confirmation really.

I think you will be OK too.
