Built your own Contender
Plans For Building a Contender; Buying an ISAF Plaque
Plans for building a Contender are available for purchase. Plans must be purchased from the International Sailing Federation (ISAF).
It is very strongly recommended to prospective amateur builders that accurate copies of the measurement templates be secured and used to check the progress of the hull shape as the boat is being built. Building from plans alone is likely to result in a boat which does not measure. All Contenders must be measured and the measurer uses these templates to check conformance to specification.
All Contenders must have a plaque purchased from the ISAF permanently installed in a visible location within the cockpit. These plaques must be purchased directly from the ISAF.

The plan sheets available are shown to the right.
We recommend items1,2,3A,4 and 8.
Item 7 is no longer relevant.
An amateur builder is not permitted all glass fiber construction.
Therefore item 6A may not be very useful to an amateur.
Amateur builders may build a wood boat (timber construction). Amateur builders are also permitted to acquire a glass fibre hull built by a licensed builder and then add the wood parts necessary to construct a composite hull.
Many people have successfully built their own Contender dinghies, and it is probably not as difficult as it seems at first sight. Most of these amateur builders will be happy to share their experiences with you if you are starting your own boat building project. Best addresses to start with are the national Contender associations which will be happy to bring you together with any amateur builder in your country. Only licensed builders may build in GRP (glasfibre construction).
