More than £100,000. That's what a former Royal Navy Officer must pay following a collision between his yacht and an oil tanker during Cowes Week two years ago.
Lieutenant Roland Wilson was today found guilty of three counts of breaking maritime regulations.
He was fined just three thousand pounds. The rest is for court costs.
Footage of the collision has been viewed almost one million times on YouTube.
Andrew Pate spoke to eyewitness James Stevens and Captain Jeremy Smart from the Coastguard & Maritime agency.
