There were a couple of references here to ''short cuts taken in the north". Up here (in the "true north strong and free"), I've never even seen cinder or concrete block used for blocking a boat.
Here's a couple of pictures of our boat taken yesterday. This is even just temporary blocking for three days. It was hauled on Friday and is getting shifted into heated storage on Monday.
The large blocks were brand new - so you can get them somewhere. The keel had already sunk a quarter inch into the top 2 x 4 - lots of pressure on a small surface area.
I'm sure there are probably tolerance levels for different boat weights, but as I said, I've never even seen someone use cinder or concrete blocks in marinas around this area.
The other concern I would have using cinder block in the north is water intrusion and freezing. Any hairline crack or void will fill with water and it wouldn't take long for the block to split in two after a couple of repeated thawing and freezing cycles.
