The Maritime Administration has increased its Title XI loan guarantee commitment on the Chilbar, a chemical carrier owned by Chilbar Shipping Co., from $24,244,000 to $27,148,000.

The recently announced increase was a result of the inclusion of the cost of the vessel's stern section in the computations of the ship's actual cost. The stern section of the Chilbar was taken from a ship called Eagle Traveler. Its integration into the design of the otherwise new chemical tanker was not discussed in Chilbar's original Title XI guarantee application.

The Chilbar was built by Newport News Shipbuilding Co., Newport News, Va., and is currently in service. The vessel's Title XI guarantee covers 87½ percent of its $31,027,162 actual cost.
