Triton makes nice small single and dual axle trailers. You can even build it to your specs online.
My own idea of a good gear trailer for my needs is this.
It will hold 3 dirtbikes or 2 street motorcycles (I hope). It has electric, propane, heat, cooling and can be ordered with a top rack too, which I did not order.
Its a bit more than the basic cargo trailer.
Not sure if this has the length needed for the long open water kayaks (102" to the cabinets).
It is built to order so it may be available without cabinets too.
Micro-Lite Cargo-Lite Extreme. I get it on Friday!
