Took a piece down the lake to test it for buoyancy, and it floated no problem..... So went back and got the rest, screwed all 16 metres together and pushed it out onto the surface.......
It floats like a dream and turns over really easily , albeit with no pot attached........
It was a bit "snakey" at 16mtres, but I applied the foam really quickly and I'm pretty sure there were some air locks inside some of the lengths, which wouldn't of helped...
