This is a reliable way of moving heavier boats or multihulls across the hardstand.
Before use, the ways are greased with hot tallow using a brush. Heavy planks are placed lengthwise under the cradle on top of the ways. There is a very remote possibility that a plank could jam against the end of a way which might be sticking up a little due to the uneven ground. Vigilance is required by all the team to ensure that should this start to happen the tractor driver is immediately informed to STOP. The problem can then be easily resolved. The diagram below demonstrates what could happen.
