WW says:

The pipe diameter required depends, as I am sure you know, on the load applied and the length of the piping, to avoid pressure drop and an incorrect flame picture, when all burners are lit under full load. This forms part of the standard check during the BSS.
There are specific regulations for LPG installations in boats- you can get these from the LPG installers group- for the references, see the boat safety scheme essential guide.
Ideally, you need a gas safe engineer, who is qualified for marine installations, as the standards are much higher than domestic installations.

you are best running 10 or 12mm pipe. Do not use 15mm water pipe and do not solder the pipe, use proper compression fittings.

I think it should be 10mm but in saying that i think you should contact a gas fitter and asap for your own safety
