I'll post pictures of my new lift platform when there is a little more sunlight in the Northern Neck of VA..
We went with a mini mag 2800 PWC/skiff lift by magnum boat lifts (boat lifts unlimited) the 2 units are mounted 12' apart. I used 14' extension ladder sections to span the 12' between arms. I put down 11" x 1/2" trex trim ( thinner than decking trex) for decking so it wouldn't be too buoyant . I end up with a 14'X 6' platform that has room for the TI and walking space on both sides.
Works great! I added some cobblestone ballast just to be sure the platform wouldn't float, as that is a big no/no. We also mounted the lift controls so I can reach them from the platform when it is in the water. Only takes a couple of inches to float a TI. the platform makes it easy to tidy up around the TI, fold/unfold amas, roll up tramp, handle the mast, etc.
I still need a cover to replace the gorgeous walmart tarp I have on it currently. Best part is I don't have to fight barnacles on it every winter unlike a float.
Luv my new TI !
