NRC researchers built the tool using several types of data, says project leader Dr. Ayhan Akinturk. For example, they examined results from dozens of past model tests conducted in NRC-IOT wave tanks, but their main focus was on real people in real boats. Tool developers took a statistical look at fleet safety records for different boat designs - to find out whether particular types are accident-prone - and analyzed the ability of different designs to right themselves in a roll. The team also looked at weather conditions (wind, waves and ice) during accidents as well as how fleet vessels were operated, including what gear was used and how fishing license conditions (e.g. were catches stowed on deck or below?) may have affected handling.
