Maximum speed for 27163 shp = 29.00 knots
Approximate cruising radius, 3500 nm / 10 kts
Typical complement: 108-141
Estimated cost, $683,000 (£171,000)
Remarks:
Caution: Hull structure is subject to strain in open-sea
conditions.
Caution: lacks seaworthiness -- very limited seakeeping ability.
Caution: Magazines and engineering spaces are very cramped,
and lack adequate watertight subdivision.
Caution: Delicate, lightwight machinery.
Ship has quick, 'lively' roll; not a steady gun platform.
Cramped ship; poor crew accommodation, limited working space.
