The debate surrounding the cost to value of advnanced tractor tugs is ongoing in the marine business, as most normal operations do not always require the swift manuevers and brute strength these vessels posses. Some owners say the tugboats as “overkill”, and bemoan the higher cost of maintenance in comparison to traditionally driven boats. When an incident such as the one that was recently logged in the Prince William Sound of Alaska happens, though, the tremendous value of these impressive tugboats is apparent and without compare. On July 10, two Crowley escort tugs prevented an accident between an oil tanker and fishing vessel in Prince William Sound.
