Speedlink Vanguard was a 3,514 GRT train ferry which was built in 1973 as Stena Shipper. She was charted to a New Zealand operator on completion and renamed Union Wellington and saw further service as Alpha Express and Stena Shipper before entering service with Sealink as Speedlink Vanguard. The ship was involved in a collision with European Gateway in 1982, which sank the latter ship with the loss of six lives.
