ISO 6216:1980

Overview

ISO 6216:1980 - Shipbuilding, Inland Navigation: Pilot Craft - Classification and Basic Requirements is an international standard that defines classification, design considerations and basic safety and equipment requirements for self‑propelled pilot craft used to transfer pilots to and from merchant ships in closed waters, estuaries and open‑sea roadsteads. First published in 1980, the standard aims to harmonize terminology, improve pilot transfer safety and support international maritime operations. It also notes that certain pilot craft (especially those used mainly for leading) may be exempted wholly or partially by competent authorities.

Key Topics and Technical Requirements

• Classification by craft type: Pilot craft are grouped into three types (small pilot skiffs, pilot launches, and larger pilot boats) based on displacement and operational role.
• Geographic/operational groups: Three climate/service groups (A = polar, B = temperate, C = tropical) determine machinery execution, cabin arrangement and equipment requirements.
• Seakeeping and motion limits: Minimum roll period requirements are specified (example: longer roll period requirements for larger pilot boats vs launches) and craft unable to meet limits must have roll‑damping devices (stabilizers, bilge keels, etc.).
• Pilot transfer capability: Pilot craft must be capable of safe transfer in waves up to 3.5 m and provide clear, unobstructed forward deck space and anti‑slip surfaces for embarkation.
• Communications and navigation equipment: VHF (ultra‑short‑wave) radio stations for international channels (pilot boats should carry a main and a reserve station), and dual radars (principal + reserve) are required. Special navigation lights, unified signals and day signals for pilot operations are mandated (and must conform with collision regulations).
• Maneuverability and propulsion: High maneuverability is required; twin‑propeller regulated‑pitch arrangements, diesel‑electric or bow thrusters are recommended to facilitate close approaches.
• Structural and equipment features: Ice strengthening for group A, de‑icing equipment, robust anchoring gear, lifting appliances located near the midships, elastic or approved fenders, and suitable lifesaving equipment (pilots counted as part of crew) are specified.
• Marking and visibility: Special hull/superstructure colors and unified inscriptions per ISO 6217; display of the “pilot on board” signal flag.

Applications and Who Uses It

• Shipbuilders and naval architects designing pilot craft for inland and coastal operations
• Port authorities, pilot associations and harbor masters specifying pilot craft procurement and safety standards
• Classification societies and flag State regulators assessing compliance and certification
• Maritime equipment manufacturers supplying radars, radios, fenders, transfer platforms and stabilization systems
• Shipyards and operators conducting safety audits, retrofits or operational risk assessments

Related Standards

• ISO 6217 (pilot craft markings and inscriptions) - referenced for unified markings
• International collision regulations (COLREGs / RPCM‑72) - for navigation lights and signaling requirements
