I have been tinkering with the great "instant on/off" PVC loader design you may have seen on youtube. It uses industrial suction cups to mount a PVC cradles to the bonnet and windshields, exactly when and where you need it.
They needed to be stretched and reinforced to accommodate the AI hulls shape and weight. I also added large padded rollers to make the job of raising and lowering the 16ft hull a piece of cake. The job can now be done one-handed or by someone who is not a weightlifter.
You just need a 4 HEAD SUCTION CUP from Northern Tool + Equipment, some 1" and 1.25" Sched 40 PVC and the proper plastic glues. Use blue pvc primer and grey PVC glue or a multipurpose cement. You are bonding PCV to the ABS grip. I added a dowel and stainless wood screws to add stability.
(Answered this in a PM - but here it is for the clan)
You can't see them all, but there are 3 layers.
The supporting frame is all 1"pipe and fittings (glued and screwed).
Before gluing, I slipped sections of 1.25" PVC over the exposed sections of 1" pipe. So now, it it double layered between the fittings.
This outer layer is not glued, so it spins freely, providing "wheels" for the kayak to roll on. It works great for this, reducing resistance and adding strength at the same time.
Because the outside diameter of 1" fittings and 1.25" pipe is the same, you also get a nice smooth surface that is less likely to scratch up the plastic kayak hull.
I covered these "wheels" with foam insulation (the third layer).
Because the AI is close to 100 lbs, you need to keep the PVC lengths short and reinforce all joints. The ABS to PVC is heavily glued and screwed but not really secure enough. A dowel was added so that the screws have something to bite into. This helps prevent the whole thing from twisting and breaking when only one side of the loader has weight on it.
Glad you like it. The greatest thing about this loader design is how easily it removes and stows away. Takes just seconds...
