Single Trailex Hobie Trailer Load Capacity?

Not much room for a trailer in my tiny garage.
Looking at the "single" trailer and possibly stacking a couple of kayaks occasionally.
A Pro Angler with an Outback on top so I want to find the load capacity.
Also, anyone know the speed rating of their tires, will they go 60-70 mph?

thanks

The trailex I have SUT 200 S is rated for 200 lbs. I have a Adventure and have rigged it to stack a Outback on top. No problem on the interstate at 70 mph. Easy to move around. I worked on the supports quite a bit so I could place the Adventure rightside up without getting dents in the hull. I mount the Outback upside down on supports I built over the Adventure.

If you get to the point that you need pictures let me know.

I have the same trailer, however; I only have a loaded PA on it. Probably not more than 175 pounds, as I put a lot of stuff in the cockpit and behind the seat.
That said, I'll tell you I just returned from a 3k trip pulling it behind my Equinox and had no problems what so ever. What I really like is the fact that even loaded I can unhook it from my car, and by hand park it.
