HST-2, formerly named USNS Puerto Rico and Alakai, is a vessel owned by the United States Navy Military Sealift Command. She was originally Hawaii Superferry's first high-speed ferry. The vessel was later chartered by Bay Ferries Limited to operate a ferry service between Maine and Yarmouth, Nova Scotia.

The design of the Spearhead-class expeditionary fast transport is similar to the two high-speed ferries operated by Hawaii Superferry, both built by Austal USA.
