You're welcome, glad to be of help! I can't take all the credit; ITD is the one that found their website and made the original post, all I did was recycle it here! After I had finished reading your previous post, the first thing I thought of was that Boat Lift thread and the link posted there; I knew the wheels might solve your problem, depending on the terrain you had to deal with!
I think the Boat Lift Helper people need to expand their product to fit it to other in-water items, like swim platforms.
