Athwartships

What is Athwartships?

Athwartships is a fundamental maritime directional term that every professional seafarer must understand comprehensively. This nautical terminology is crucial for safe navigation, effective communication, emergency response, and regulatory compliance under international maritime conventions.

For Indian seafarers preparing for IMU-CET entrance examinations or DG Shipping Certificate of Competency assessments, comprehensive knowledge of athwartships is essential. This article provides detailed technical information, practical applications, examination strategies, regulatory context, and communication protocols relevant to Indian maritime education and certification.

Historical Development and Evolution

Maritime directional terminology evolved from centuries of seafaring tradition:

Ancient Seafaring Origins: Early mariners developed standardized directional terms enabling clear communication aboard vessels. These terms derived from ship construction, sailing vessel operations, and practical seamanship needs.

Sailing Ship Era: Traditional terminology from age of sail remains in use today. Terms like athwartships originated from specific vessel locations, equipment positions, or operational requirements during sailing ship operations.

Steamship Transition: Transition from sail to steam power retained traditional terminology despite changing vessel designs. Maritime tradition preserved established terms ensuring continuity across generations.

International Standardization: International Maritime Organization and maritime nations agreed on standard English terminology for international shipping. Standard Marine Communication Phrases (SMCP) codified directional terms for global use.

Modern Application: Contemporary vessels use traditional directional terminology integrated with modern navigation and communication systems. Understanding these terms remains essential despite technological advancement.

Indian Maritime Education: DG Shipping and Indian Maritime University emphasize traditional maritime terminology in training and certification programs. Indian seafarers must master English nautical terms for international shipping operations.

Technical Specifications and Usage

Precise Definition

Athwartships refers to [specific directional reference on vessel]:

Exact Location: athwartships indicates [precise position/direction relative to ship’s structure and heading]. This standardized reference point enables unambiguous communication.

Reference Frame: All directional terms use ship’s centerline and heading as reference. These relative directions differ from compass directions, requiring clear understanding.

Consistency Across Vessel Types: athwartships applies consistently whether on cargo ships, tankers, passenger vessels, or offshore units. Universal terminology enables crew transfer between vessel types.

Communication Clarity: Using proper terminology prevents confusion during navigation, cargo operations, emergency response, and routine vessel operations. Misunderstanding directions creates safety hazards.

Relationship to Other Directional Terms

Athwartships relates to complete set of maritime directional references:

Port and Starboard: Left and right sides of vessel facing forward. These terms never change regardless of which direction person faces on ship.

Forward and Aft: Directions toward bow (front) and stern (rear) of vessel. Used for longitudinal position reference.

Bow and Stern: Front and rear of vessel. Physical structures as well as directional references.

Amidships: Center portion of vessel between bow and stern, midway point.

Athwartships: Direction across vessel from side to side, perpendicular to centerline.

Aloft: Upward direction, above deck level in rigging or superstructure.

Positional Terms: Abeam (perpendicular to ship), Astern (behind ship), Ahead (in front of ship).

Communication Protocols

Standard communication using athwartships:

Bridge Communication: Officers give helm orders and navigation commands using precise directional terminology. Standard phraseology prevents misunderstanding during critical operations.

Cargo Operations: Deck officers direct cargo handling using directional terms identifying specific holds, hatches, or deck areas. Clear communication ensures safe, efficient operations.

Emergency Response: During casualties, directional terminology enables rapid, accurate communication about fire locations, flooding compartments, or damage positions. Time-critical situations require precision.

Routine Operations: Daily maintenance, watchkeeping, and vessel operations use standard directional terms for consistency and clarity.

Practical Applications Aboard Ship

For Deck Officers

Deck officers use athwartships extensively in all operational contexts:

Navigation Commands: When giving helm orders, officers use precise directional terminology. “Steer to starboard” or “hard to port” must be unambiguous for helmsman response.

Mooring Operations: During berthing, officers direct mooring line handling using directional references. “Heave away forward spring” or “Slack aft breast line” requires exact terminology.

Cargo Operations: Chief Officers plan cargo using directional references. “Load containers in number 3 hold, port side” or “Discharge general cargo from after holds” specifies locations exactly.

Safety Management: During drills and emergencies, officers use directional terms describing station locations, equipment positions, and assembly areas. “Fire in number 2 hold, starboard side” enables rapid response.

Vessel Handling: Ship handling requires continuous directional references. “Bow swinging to starboard” or “Stern moving to port” describes vessel movement precisely.

For Marine Engineers

Engineering officers use directional terminology for:

Equipment Location: Describing machinery locations uses directional terms. “Main engine cooling pump, forward, starboard side” identifies equipment precisely.

Damage Control: During flooding or fire in machinery spaces, engineers use directional references communicating damage location. “Water ingress in engine room, aft port corner” enables targeted response.

Maintenance Planning: Work orders specify equipment locations using standard terms. “Inspect purifier in ECR, forward of main engine” ensures crew locates correct equipment.

Communication with Deck: When coordinating with bridge during maneuvering, engineers use consistent terminology ensuring mutual understanding.

For Ratings

Deck and engine ratings require working knowledge of athwartships:

Following Orders: Ratings must understand directional terminology to execute orders correctly. “Prepare mooring lines forward” or “Clean cargo hold, starboard side” requires knowing directions.

Safety Drills: During abandon ship, fire, or other drills, ratings muster at assigned stations identified by directional location. Understanding terms prevents confusion during emergencies.

Maintenance Tasks: Bosun assigns deck maintenance using directional references. “Chipping and painting, port side accommodation ladder area” specifies work location.

Reporting Conditions: Ratings report observations using correct terminology. “Cargo shifting in number 4 hold, port side” enables officers to assess situation quickly.

Common Misconceptions About Maritime Directional Terms

Misconception 1: Left and Right Suffice for Communication

Incorrect Belief: Simple “left” and “right” directions are adequate for ship operations.

Reality: “Left” and “right” are ambiguous aboard ships. They change based on which direction a person faces. A crew member facing aft (toward stern) has opposite “left” and “right” from someone facing forward. This ambiguity creates dangerous confusion.

Athwartships and other maritime directional terms provide absolute references regardless of person’s orientation. These terms are non-negotiable for safe operations.

Professional Standard: Using non-standard terminology during examinations results in failure. DG Shipping examiners specifically test proper terminology usage.

Misconception 2: Directional Terms Apply Only to Ship Parts

Incorrect Belief: athwartships only describes physical ship structures, not directions or areas.

Reality: athwartships functions as both:

Understanding multiple applications essential for comprehensive competency.

Misconception 3: Terminology Understanding Can Be Approximate

Incorrect Belief: Close enough understanding of directional terms suffices.

Reality: Exact understanding is mandatory. During emergencies, imprecise communication causes delayed response, misdirected assistance, and potentially catastrophic outcomes.

“Fire in forward hold” versus “Fire in number 1 hold” may describe different locations. “Flooding port side” versus “Flooding portside tank” have different implications. Precision saves lives.

Misconception 4: Modern Technology Eliminates Terminology Need

Incorrect Belief: GPS coordinates and ship schematics make traditional directional terms unnecessary.

Reality: Traditional terminology remains essential because:

SOLAS Requirement: Standard Marine Communication Phrases use traditional terminology. International maritime law mandates this knowledge.
