Robert Allan Ltd. is pleased to announce that the RApport 2600 tug Hayden Grace was successfully delivered to Bay-Houston Towing Co. and started her commitments in Galveston, Texas in November. The newly completed RApport series tug was constructed at Master Boat Builders Inc. of Coden, Alabama. Three vessels of this type have been ordered by Bay Houston Towing.
The RApport 2600 is the first in her series of vessels for Bay Houston Towing and takes some design cues from previously completed Z-Tech® tugs designed by Robert Allan Ltd.
