Ronnie, I just have to get around to doing a video to show it properly but here is some info.
I built this rack, before getting the TI, with adjustable runners via the garage door chanel used.
I then mounted a winch in my garage and replaced the chains with a hook which goes through the front mirage drive hole.
So I store the TI, on the frame, on those runners in the grooves in the base of the hull, right way up. Coming up to two years without problems to the hull. I think it is important that I have a block which is exacltly under the mast step, to take some of the load.
I also have a hand cart with smaller runners and big wheels, which sits on the rack, under the TI.
To unload, I simply slide off the back of the car, onto the cart to take down the ramp or across the beach. I have tied a long rope to the cart to get across soft sand or up a steep ramp.
I found that the back corner of the hull touched the ground so I made this device that goes in the rudder mount, to protect the hull and keep it level when unloading or loading. Also makes a nice handle to use.
I also mounted a pole to the front cross member of the car, via a Hayman Reece type fitting.
That pole supports the front of the frame because there is so much overhang. I found I also had to fit cables from the wheel well, through the bonnet gap to that pole. Strong side winds were putting too much strain on the fitting of the pole.
All in all, works very well, sitting on standard roof racks which stay on the car.
There is no doubt the TI is heavy to lift the nose up onto the rack. I suspect when I get older I will want a winch to do that, but for now is good.
If you want further details, including detailed photos and size, let me know.
