Sause Bros. updates venerable Mikiona-class tugs

Professional Mariner StaffAmerican Tugboat Review, Tugboats & Towing
When Sause Bros. President Dale Sause ordered a pair of 128-foot offshore tugs in 2018, he had complete confidence in the finished product. It’s not often an owner can be that certain, particularly when working with a new shipyard.

Mercury Transport updates proven design for new B.C. tug

Professional Mariner StaffAmerican Tugboat Review, Tugboats & Towing
