Loch Etive power cable clearance

Just ask them to switch it off whilst you transit

That info used to be available from The Canal Authority. We used to lower our telescopic top masts on many a ship. Poor Sparky would have to re rig his antenna.

On the standing mast route through Netherlands there's an opening electrified railway bridge. The overhead wires open with the bridge. I wonder if all the trains down the line judder to a halt for a few minutes as the boats go through.

Thanks. I would love to know how accurately they measure the height of the wires. I presume they measure load and air temperature at the same time to calculate droop.

On the bright side, if you are below the safe clearance and still end up with a smoking stump where your mast was, you can probably sue somebody.

Not if you're using Admiralty Charts - Crown immunity!
