Hello all, a newby here. Apologies if this has been asked before but I did a search and couldn't find an answer. We're currently looking to buy a boat for living aboard continuously cruising, looking on the CRT website it says that the locks on the Calder and Hebble and the Huddersfield Broad are 57ft 6ins. My question is " could a 60ft boat sit diagonally in the locks or must we stay below the stated max ?? " Thanks in advance nige
