APPENDIX 22 - Coastal Rowing Competition Regulations Event Regulations and/or Departures from the FISA Rules of Racing

13.1.3 Minimum permitted width of the boat measured at the following two locations, all measurements taken externally at the station of maximum overall beam:

  1. width overall (point 1);
  2. width at the Secondary Beam Measurement Point which shall be located at the specified height from the deepest point of the boat at that station (point 2).

The maximum permitted length and minimum permitted weights are as follows:

There is no minimum length for Coastal Rowing boats. The minimum permitted widths are as follows:


Maximum length (m)

Minimum weight (kg)

0.23 m

0.70 m

C4+, C4x+

1.3 m

0.30 m

0.90 m

In Coastal Rowing boats, all rowers must be seated in line over the axis of the boat and all coxed boats shall be designed so that the coxswain is required to sit upright to the stern of the rowers.

In addition to the flotation requirements referred to in Bye-Law to Rule 39 and in the "Minimum Guidelines for the Safe Practice of Rowing", Coastal Rowing boats should be constructed with three (3) watertight compartments. These compartments may have watertight hatches or ports for access to these areas.

Boats must be designed and constructed so that the hulls are self-bailing; self-bailing shall mean that water in the boat will automatically be removed through hull bailers by the forward movement of the boat, or by a cockpit floor properly pitched aft to an open transom.

APPENDIX 22 - Coastal Rowing Competition Regulations Event Regulations and/or Departures from the FISA Rules of Racing

Traditional Coastal Rowing Boats of Different Design

The organising committee of an international Coastal Rowing regatta may establish separate events for Coastal Rowing boats of different traditional designs or may allow such boats to compete in races together with boats of other designs, and at the discretion of the organising committee may or may not categorise each design individually for the purpose of the competition.

Requirements for Coastal Rowing Boats and Equipment

All boats must meet the safety requirements set down by FISA and any additional requirements set down by any national, regional and/ or local authority for participation in the particular Coastal Rowing regatta. In particular:


Boats must meet the minimum flotation standards set down by FISA, either with the required watertight compartments or built-in flotation utilising bags or tanks. (At an international Coastal Rowing regatta where the organising committee accepts entries from traditional Coastal Rowing boats exceptions to the FISA Flotation Guidelines may be made by the organising committee for a class of boats if the boats meet all other safety requirements.)

Boats must carry a life jacket for every crew member, of a type which meets recognised international standards. Coxswains must wear a life jacket at all times in the boat;

Boats must have a towing eye located approximately 100 mm above the loaded waterline on the bow fitted with a 15m buoyant line. Both the towing eye and the line shall be of sufficient strength to allow safe towing of the swamped boat with crew members on board in strong wind and sea conditions. The loose end of the line must be within hand-reach of a rower for the purpose of throwing to a rescue boat if required.
