Will it float?

At the moment, my main concern is to keep the boat afloat. I have not been to the marina in 2 weeks and I'm slightly worried that I will find it at the bottom of the river or that the engine will be flooded. These are valid concerns as it has about a foot of water every time I go. Last time the manual bilge pump did not work so if the engine doesn't start, I'm slightly screwed as I don't have any emergency buckets on board..
