Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, rides out heavy weather easily
Low-stowed cargo simmed as additional bunkers.
Normal radius is 8,000 nm on Bunkers at max (BAM) of 510 tons
Additional bunkerage (3,900 tons) represents cargo.
Breakdown of miscellaneous weight:
Cargo handling gear - 150 tons
Provision for deck cargo (typically timber) - 250 tons
Provision for cargo stowed on shelter deck - 1,600 tons
Breakdown of low-stowed cargo:
Deep tanks aft for liquid cargo (palm oil, latex) - 900 tons
Reserved for general cargo - 3,000 tons
Survivability and crew data reduced for commercial service
