Tugboats 'Izbaizabal Diez' & 'Izbaizabal Once' delivered to Spanish tug company Remolcadores Izbaizabal by Astilleros Armon in Navia, Spain.
The design features a full raised forecastle running nearly half the length of the tug to provide a high standard of accommodation and the best possible sea-keeping capability for operation in exposed conditions.
