saves thinking quickly

[Highlander]

Around here, we have walk ways around the fish farms made from metre square polystyine [sp] blocks, these could easily be brought together to make what would be an unsunkable craft,.... propulsion system would have to be a plastic sheet and a couple of straight branches.

Every year as part of the village `games`we have a raft race, and some of these crafts are a work of art,... no nails are allowed
