Class societies like IRS, DNV, ABS, and Lloyd’s Register certify magnetic compasses based on accuracy, materials, durability, and construction. Certification ensures the compass is seaworthy and compliant with SOLAS and IMO rules. It also helps meet insurance and survey requirements. Certified compasses bear engraved plates with type approval information.

Compasses approved by DG Shipping are certified for use on Indian-flagged vessels. These compasses must meet performance and construction standards set by the Marine Equipment Directive (MED) or equivalent. Approved models are typically listed by manufacturers and suppliers in India. A compass without DG Shipping approval cannot be installed on merchant vessels.
A marine compass audit in India involves inspecting compass accuracy, mounting, lighting, deviation correction, and service history. These audits are usually part of ISM code compliance or internal safety checks. They help ensure the vessel’s compass meets DG Shipping, SOLAS, and IMO standards. Certified compass technicians or marine surveyors perform these audits. A report is […]
During annual and special ship surveys, inspectors check the condition, calibration, and installation of magnetic compasses. Surveyors verify the presence of deviation cards, test lighting, and ensure proper alignment. Compasses are reviewed under national (DG Shipping) and international (IMO, SOLAS) standards. Failure to meet compass requirements can lead to detention or repair notices.
Under the SOLAS (Safety of Life at Sea) convention, ships are required to have at least one magnetic compass and one spare. These compasses must be correctly installed, fully functional, and maintained. They must also have proper deviation cards and be readable from the helm. SOLAS further mandates compass repeaters for vessels over certain tonnage. […]
The International Maritime Organization (IMO) sets mandatory regulations for marine compasses under SOLAS. Ships must carry a magnetic compass that is visible from the wheelhouse, illuminated, and regularly calibrated. It should function independently of electronic systems. IMO-approved compasses must meet performance standards for accuracy, durability, and readability. Compliance ensures global navigational safety and smooth port […]
The Directorate General (DG) of Shipping, India mandates that every seagoing vessel be equipped with a magnetic compass approved by a recognized authority. The compass must be properly calibrated and installed in a suitable location, such as a binnacle on the bridge. It should be readable from the steering position and regularly maintained. DG Shipping […]
Commercial vessels such as cargo ships, tankers, and offshore platforms use high-precision magnetic compasses housed in binnacles with repeaters and calibration tools. Indian marine suppliers offer IMO-approved compasses with optional deviation cards and correction services. These are essential for global navigation, backup, and emergency systems.
Inland vessels in India such as tugs, ferries, and river crafts use compact magnetic compasses tailored for shallow and narrow water navigation. These compasses are often portable and durable, resistant to shock and vibration. Inland navigation demands quick heading changes, making accurate compass readings essential. Suppliers offer basic and advanced models.
Yachts require compact, high-accuracy magnetic compasses with shock resistance and easy readability. These compasses are bracket or flush mounted and often used alongside GPS and chartplotters. Indian yacht suppliers stock Ritchie, Plastimo, and other trusted brands. A magnetic compass remains crucial as a non-electrical backup system for yacht navigation.
