    Netham lock in Bristol is open by default. Only closes for high spring tides and when the River Avon is in serious flood. Yes it does seem strange, even after using it dozens of times.

    That's a strange arrangement unless the water tank has been modified. Obviously an electric bow thruster motor cannot be under water.

    what he said.

    Did what little instruction you did get convince you to drive at a safe speed?

    Ah! That must explain why sometimes she doesn't speak to me for days.

    perhaps the moderators should arrange for all threads to be automatically closed and archived if there has been no new post for say 3 months. Still available for reference, but not for responding.

    but it needs to be hot to vaporise to a dangerous level in the first place, unlike petrol or lpg for example.

    I suppose the diesel engine size would be matched to something approximating the AVERAGE power demand, whilst a diesel prime mover is matched to the Maximum demand. So the average boat may get away with about 10KW or say 15HP, allowing for losses.

    Diesel won't ignite when someone lights up a fag or even if he dunks it in the diesel bilge. http://www.ybw.com/forums/archive/index.php/t-38539.html

    if I was going down that route I would design the boat to carry a sound-insulated generator pod on the stern deck. For example, Fischer Panda.

    ditto

    or may be fixed to the calorifier, in the case of a vertical cal it is probably incorporated with the hot water outlet at the top of the tank.

    not necessarily true. If the boat has an electrical system (e.g. lighting) then it must comply. Ditto for a fixed engine, gas, etc. Ref 3rd paragraph of clause 1.13 of BS scheme requirments. <http://www.boatsafetyscheme.org/media/180428/bss%20guide%202005%20complete%20web.pdf>

    you could use a jacket, same as is used on domestic hot water cylinders. Available from any DIY outlet.

    The guy has a small GRP cruiser with limited electrics. Nothing wrong with the red handled switch in such a situation, but be aware that you need to make 2 new cable terminations with suitable lugs. I am surprised the BSC surveyor would accept 'quick release' battery terminals, but if he says so, and as you don't need the certificate to travel on the Thames, that may be the best option.

    Why not make a panel with an aluminium angle frame, screwed in place and set in a suitable sealant. Looks good and protects the edges which tend to rot.

    yes, on reflection that seems right. The water cools as it passes through the coil, so it tends to sink. Thanks.
