: Hi Jeff,
: For multiple kayaks, make up sectional uprights with a cross-tree on each
: section. These could be bolt-on or clevis-pinned, bolt-on is sturdier, I
: think.
: The sections could be timber made with metal sleeves for the connection
: points.

: For wet gear and paddles, a set of boxes, with drainage and airflow holes,
: mounted on the trailer bed would work well and be lockable.

: Hope this helps,

I am in the process of setting up our trailer for carrying 6 kayaks. The frame will lift off so the trailer can still be used for the chores we have to do. I'm running a 2"x1" box across the front and back with 1"square box risers and a 1"square top rail.I estimate total weight of the frame to be around 30kgs so the wife will help to lift it on to the trailer.
I'll post a photo when its done.Got sick of running 2 vehicles and as our petrol is more expensive than yours is and it was time to do some thing about it.
Robin.
