Will it float

Wood floats, but the ability to stay upright does come into question, some additional work needed, before it is allowed into the centre of the lake.

Pulled on a string is some fun, but you really want to see if it will sail on its own.

If it sinks at the edge, it can be saved as the water is only about six inches deep.

Wellingtons take on water once you get further than three feet from the edge.

Mud and sharp stones stop you going in without boots on.
