Can my JK's roof handle a 150# 12 foot jon boat? I was planning on strapping the boat down upside down on top of the jk and carpeting a few 2x4's and laying them as a buffer between the top and the boat. The lake is about 2 hours from me that I fish at and there is no way to get a trailer back there. Any thoughts?

 

Did you check the owners manual? I think I recall my manual addressing this topic.

 

I'd say yes!
I've seen people stand on theirs.

 

Just checked. My manual days not to do it. However, I think 150 pounds would be ok if you really distribute the load over as large an area as possible and by no means should it be tied to the roof. Should only be tied to something structural like bumpers.

 

I've sat on the roof with another person and it was just fine. It was probably close to 300 lbs combined weight.

 

Sitting and standing on the top are not good indicators of load capacity of the moving vehicle.

In the OP's case, consideration also has to be given to the boat being thrown side-to-side on the rough trail.

 

Here is what I would do, take off the top, strap the boat to the roll bars, damage nothing this way.

 

True, however I was just giving an example of my experience with a lot of weight on the hardtop. As Mtn Man Tim said, whenever I haul my paddle boards, the easiest and safest way I have found is to strap them to the roll bars. Until I get my hands on a roof rack!

 

Feedback is appreciated. I have decided to go with a canoe that weighs about 85# I'm pretty sure the roof will be just fine with foam blocks between the canoe and the roof. Anyone have any experience with the surco hardtop adapters?
