£100,000 sounds a lot, but when your mega-million£ ship is heading towards the rocks... Suddenly an expensive tug assist doesn't seem so bad.
Angus, I know it isn't piracy... My insurance company charges me 10,000s pounds per year and if I need assistance from a third party, then they pay- but as someone else says, insurance premiums go up dramatically. However, a lot less than if you refuse assitance and your vehicle/ship is destroyed...
