246 WA trailer setup question

[Familyrig]

Hello,

Working on slowly rebuilding the Aluminum trailer that came with my 246. This last weekend I replaced the old rusty galvanized uprights holding the bunk boards with aluminum uprights thinking this would be ok but it is not. The aluminum uprights appear to be flexing toward the outside of the boat which makes sense based on the hull pushing out on them. After doing some online research I found some people have doubled up on the uprights solving the strength problem, see attached photo. Should I just order 8 more aluminum uprights and go down this path or suck it up and go back to galvanized that worked?

I also opened up a can of worms researching 246 bunk supports and realized my bunks, I believe are to far apart. Mine measure in at 53" inside to inside board. Most information I can find put the bunks at 44-45". I was able to find a PDF on this site showing trailer setup but the bunk width is not filled in? I would really appreciate if anyone can measure their bunks and confirm the proper width.

Thanks, David

I ditched my aluminum flexible flyer I could never compensate for the amount it flexed. I went with a galvanized Venture with14ft bunks and it’s a dream to trailer. I believe my inside measurment on the bunks is 33“ to match the stringers. I posted picks of it on this site somewhere.

Thank you Redneck for the info. I definitely will not be ditching this trailer. It is one of the nicest trailers I have owned with smooth towing. Way over built for the boat but I like having the extra weight capacity.

Our Aluminum Venture trailer came with galvanized bunk plates from the factory...I'm guessing the factory went with galv for a reason!

I now am thinking the same thing. The main reason I wanted to switch to Aluminum is the problems with corrosion. Not sure of your bunk setup but I was amazed lifting the brackets off the aluminum cross member how much hidden corrosion there was on the cross member. After a little research, galvanized and aluminum touching do not play nice. They recommend placing a piece of rubber between the two pieces.

Can you post the trailer set up .pdf here please? I have 246 CC and am doing a lift now and a rework of my trailer for off season storage. Post more info on your results too!

This was the only thing I could find which gave me stringer measurements & widths. It is missing the measurements I needed though. It seems like they are just not filled in? I will post more once the new uprights come in.

Hmm... very good drawing. Not sure it's to scale but I'll do some checking on the measurements. Thanks much, when you get your trailer rigged please post your measurements.
