It's not a big deal. They keep the blocks out on the "launch pad" and the dock hands (or I) strap them on.

What about when she's in storage? Does your rack also have blocks of some kind? (My Fountain spends a good bit more time in storage than on the water, and I'd like her to be properly supported.)

Bill also built blocks for his rack. They put in back in the same hole when it is in the barn. Works great.
