A lobster crate which floats is available from Atlantic Aquaculture in the USA. We are currently trying to find out if this company supplies to the UK or Ireland. A smaple crate is in the OFA office in Kirkwall if anyone wants to see it. If enough fishermen wanted them we might be able to persuade a UK company to import them. see the link http://www.atlanticaquaculture.com/flapnest%20lobster%20Crate.htm
