You are going to use cat-wheels now, right?

When I started beach launching and sailing cats, we used to laugh at the few who had beach wheels.

Then, after getting newer/faster boats, and a bottom job or two, we started using cats-wheels.

Now, I try not to ever let the hulls touch anything hard.
Everyone I know now uses cat-wheels. There have been lots of threads, on inexpensive options to home build cat-wheels.

I now think, there should be no reason to do a wear and tear bottom job, if you use cat-wheels religiously.
