Proof loads, breaking tests and certification for maritime anchors
QUICK ANSWER: ANCHOR AND CHAIN TESTING ESSENTIALS
Anchor Tests Required:
► Proof load test for all anchors exceeding 76 kg
► Drop test for cast steel anchors where required by Class
► Material tests on sample pieces per approved standards
► Visual and dimensional inspection after testing
► Freedom from cracks, deformation or defects confirmed
Chain Cable Testing:
• Proof load test on entire 27.5 m shackle length
• Breaking load test on additional sacrificial links
• Applies to chain cables 12.5 mm diameter and above
• Dimensional verification of link length, breadth and diameter
• Two successive link failures result in rejection
• Material quality verification before mechanical testing
Anchor Certificate Contents:
► Anchor type and weight excluding stock

A Comprehensive Guide to Terrestrial Sphere Geometry and Parallel Sailing
QUICK ANSWER: TYPES OF SAILINGS IN NAVIGATION
Parallel Sailing:
• Vessel maintains constant latitude (090°T or 270°T)
• Used to calculate departure from difference in longitude
• Formula: departure = d.long × cos Latitude
• Historical method preferred by sailing ships in the 19th century
• Requires no external forces acting on the vessel
Position Reference Fundamentals:
► Latitude measured 0° to 90° North or South from equator
► Longitude measured 0° to 180° East or West from Prime meridian
► Difference in latitude (d .lat) named toward direction of movement
► Difference in longitude (d.long) always shorter arc or smaller angle
► If d.long exceeds 180°, subtract from 360° and reverse the name
Direction Reference Systems:
• Quadrantal notation: 0° to 90° from North/South to East/West
• Three-figure notation: 000° to 360° clockwise from North
• True course: angle between True Meridian
