MEASUREMENT RULES

MEASUREMENT RULES

Measurement of Merlin Rockets

The Class Rules require that to be eligible for racing, a Merlin Rocket shall not only be in compliance with the Class Rules, but shall also possess a valid boat certificate with current buoyancy endorsement. A separate section in this yearbook deals with the procedures for obtaining certificates for new boats or following a change of ownership but it should also be noted that an existing certificate becomes invalid should there be a change to any other items recorded on it or following any major repair or alteration to items listed on the Class measurement form.

The Class Rules, the associated Equipment Rules of Sailing and the Class Measurement Form are no longer included in the Yearbook but the latest versions are all available on the RYA website.

Following the adoption by the Class of ISAF format rules there are now three categories of measurer.

For new boats, measurement and supervision of the initial buoyancy test must be undertaken by an RYA Approved Class Full Measurer who is also required in the case of the re-measurement of altered boats and those subject to major repairs.

Measurement of sails, certain items of equipment, re-weighing and annual buoyancy endorsements may be entrusted to an RYA Approved Class Maintenance Measurer.

RYA Approved Sail Measurers are authorised to measure sails only on any class with ISAF format rules, which now includes Merlin Rockets.

The RYA website contains full details of the requisite procedures and a list of currently approved measurers with their contact details. This is updated annually in April.

Both category of Class Measurer are class specific and are trained and nominated by the Class Association but must also be qualified as RYA

Approved Sail Measurers. The RYA runs training and certification courses for Sail Measurers.

It is normal for measurers to charge for their services but fees are not fixed and are a matter for agreement between the respective parties.

Measurement Certificates

It is a requirement of the Merlin Rocket Class Rules and the RYA that all racing boats hold a current Measurement Certificate.

To be current your certificate should contain all the correct information with regard to your boat, including the weight and number of correctors, as well as the present owner.

You will need to update your certificate if any of your personal details change or when you buy a second-hand boat. If you have bought a new boat from a builder you will be given a measurement form signed by the measurer. This needs to be forwarded to the RYA where it will be converted into a formal certificate. If you have any questions please contact Dan Alsop at [email protected]

This will be checked at various events throughout the year and applies to ALL association events so please ensure that you are not the person unable to produce your certificate as this could ultimately lead to disqualification.

If you need to update your details this cane be done throught the RYA Website https://www.rya.org.uk/dinghy-measurement-certificate, any changes to sail plan or boat weeight need to be submitted via [email protected]. Or for more information call them direct on Tel: 023 8060 4200
