Trucks & Trailers - Converting Jets Ski Trailer to Kayak/Paddleboard?Small Boat trailer

I have an old PW trailer that I want to convert to Kayak Trailer. I need a fist level area that will hold a Sunfish, as well as a 12 food Sears aluminum game fisher (though not at the same time). Above the boat, I want a structure that will allow me to transport and store multiple kayaks and paddle boards. I envision a cage of sorts secured to the frame.


I want to fabricate this on my own, and I cannot weld. Does anyone have any suggestions or pictures? Very early stages, so I am just looking for some thoughts here. I have access to a scrapyard of sorts, and can take my time here. I imago be I will be using some unbolts to secure the structure to the frame.



Thanks

I'm Looking to do something similar with a Sunfish and 2 Kayaks.
Let m know what you come up with.

I took a Long Brand small boat trailer and I bolted my Thule Transport Rack that I had bolted in the bed of my pickup and it is great. It is lite, low to the ground for easy loading and unloading. If you send me your email I can send you a picture of the rig. My email is [email protected]

A jetski trailer is very short. The issue putting longer loads on one will be the center of gravity of the load will end up being well aft of the axle, resulting in reduced tongue load. Tongue loat keeps the trailer from swaying. I am thinking extending the bed to accomodate something like a 14' boat with small outboard will end up with zero tongue load and will be very unstable. The hassle and cost of both extending the bed and moving the axle rearward under the load would seem to be more than selling and buying a more load specific trailer.
A couple of 50 lb kayaks would not be an issue, but a dual jetski trailer is sprung to carry 1000lb and the suspension will not work with such a light load meaning this thing will hop over every bump, pounding the stars out of the kayaks.
My $.02.

Plan took a detour today. The frame is rotting from the inside out, and I was able to put a thumb through the metal. This trailer is headed to the landfill.

Below is what I am going to try and re create, but on a budget. No sure what I can use for the framework, but this design will be excellent for both storage and use.

I need to identify some kind of metal rails that I can build then stabilize on the frame.
