Good advice, Denny. Brownell stands and wood keel blocks are even better!!

I use a 2-ton shop crane to lift my boat at each corner for blocking purposes, and then wood-block the keel at the transom and at the point of forward rocker, and then use wood-topped concrete blocks for transom corner support. But for lifting, Ken's A-frame is absolutely the best way (apart from having your own marine forklift).

Concrete blocks CAN be used safely, but most people use them wrongly! Most marinas use concrete blocks for static display of boats under 40'. For maximum safety, the blocks MUST BE turned thin-edge open-side upward, and then covered with a 2"x8"x16" piece of pine, or other soft wood!!
The problem is that many people use the blocks turned flat side up. This is the blocks weakest position, and blocking a boat (or anything else) this way can result in injury or death. Miner Marina in Barefoot bay had an employee severely injured back in the 80's when he blocked a 28' Wellcraft Coastal this way, and one of the stacks of blocks under the transom crumbled while he was sanding the bottom, resulting in a broken collar bone and ankle, and compound fracture of his thigh. The falling boat knocked him from his crouched position mostly outward from under the boat which then came to rest on his thigh with his left leg under the 10,000 lb boat. I was there when it happened, and it was horrific.

This is one of the great advantages of this website: before doing something stupid like that, we can ask questions and get good advice from people who've already made the stupid mistakes and learned from them!

BE SAFE! You guys are too important to become the victim of ignorance or stupidity.
