I am planning to build a trailer to haul my Hunter 28.5 shoal draft in and out of the lake where she is berthed. There is no crane facility, so the least expensive option will be to build a trailor which only needs to go from launch ramp to dry syorage and back. Does anyone have a suitable cradle which can be attached to this unbuilt trailer for sale? The whole thing would be great. I am located in the Sierras in Northern California.
