Master Boat delivers first RAL tug in series to Bay Houston

(VANCOUVER, British Columbia) — The RApport 2600 tugboat Hayden Grace, designed by Robert Allan Ltd. (RAL), has been delivered to Bay Houston Towing Co. The tug was constructed at Master Boat Builders of Coden, Ala., and started its commitments in Galveston, Texas, in November. Three vessels of this type have been ordered by Bay Houston Towing.

The RApport 2600 takes some design cues from previously completed Z-Tech tugs designed by Robert Allan Ltd. Main features of this latest RApport design include compact size and shallow draft, allowing the tugs to operate in more confined waterways than previous Z-Tech vessels, as well as a special styled deckhouse.

The customized general layout of the tug represents more than a decade of cooperation by Robert Allan Ltd. naval architects and the owners. The master and chief engineer’s cabin, along with the galley and mess, are located on the main deck, while two cabins for four crewmembers are located on the lower deck.

The main propulsion for the tug comprises a pair of Caterpillar 3512E, EPA Tier 4 certified diesel engines, each rated 2,213 hp at 1,600 rpm, driving a Schottel SRP 430FP Z-drive unit with Ø2200 propeller.

The electrical plant consists of two John Deere 4045AFM85 diesel gensets, each with a power output of 99 kW.

Ship-handling fenders at the bow consist of one tier of 36-by-18-inch cylindrical fender at the main deck level; a 20-by-18-inch W-fender below the cylindrical fender and along the sheer lines of the main deck; and 18-by-9-inch cylindrical fendering at the stern.
