Laser Centreboard and Rudder Care Information

Laser Centreboard and Rudder Care Information

By Rooster Sailing


Rooster Combination Board Bag

Your Centreboard or Rudder can be damaged by excessive heat. DO NOT leave your centreboard or Rudder in direct sunlight for extended periods, or in an area where it might get very hot i.e. under the top cover or in a car in hot sunny conditions. Also ensure that your centreboard or rudder are not under localised pressure when stored. Weight on the tip or trailing edge can distort it. In intensive heat the centreboard or rudder can warp or blister. Ideally you should store your centreboard and rudder in a purpose built bag that will help to protect them from heat and knock damage such as the Rooster Laser Foil Bag shown in the picture.

Your new centreboard or rudder is made from an advanced type of reinforced polyurethane foam. The nature of the process ensures that all components manufactured by this method have exactly the same physical and dimensional characteristics.

The foam components are extremely durable, but can suffer damage in the same way as similar wooden items. For repair purposes the polyurethane foam can be worked with normal wood working tools and methods, providing care is taken not to cut into the reinforced area that contains high tensile steel wire.

  • Minor distortion of the trailing edge or tip can sometimes be remedied by using a cloth soaked in hot water to soften the material before gently reshaping by hand.
  • Dents should be rubbed down thoroughly and filled with a Polyester Filler
  • .
  • Scratches can be treated in the same way using a suitable Gelcoat Filler, but if the high tensile wire reinforcement is exposed, any signs of rust must be thoroughly removed before filling.
  • Breakages may occur but will normally be in the leading or trailing edge areas. Cracks should be filled with an Epoxy Resin based glue which should also be used to secure any pieces which have broken away. If the piece is lost it may be replaced with wood sanded and shaped to fit, or it can be built up using Polyester Filler. Alternatively see the video below for a comprehensive guide through to repairing the most common damage sustained to Laser® foils.

After any of these operations have been carried out the surrounding area should be rubbed down with fine abrasive paper or wire wool, taking care to maintain the correct contours in accordance with class rules. The area may then be painted in the normal way if desired, using an Aerosol paint.


Interpretations of class rules vary all the time, before working on your centreboard or rudder, please check with your Class Association for their latest interpretations of their class rules.
