Sometimes the old ways are the best ways to move a boat round a boatyard

The old ways of moving boats around boatyards are the simple and safe 

Chains slings and chain blocks slow but stead and is a old well tired method of moving boats and is simple and low key, however, it gets the job done.

Plenty of rollers and planks and anything is possible with a bit of understanding of where you wish the boat to go.
