Class Rules

The RYA Technical Department maintain the Merlin Rocket class rules, as we are a national class.
You can view the rules in PDF format on their website:
RYA Technical Committee Merlin Rocket Class Rule Interpretations. 
Jib Head Support and Stiffening

(The RYA may change this link occasionally, please use their website search box or their menu entry for racing/technical if you have trouble.)

N.B. The RYA also run the Portsmouth Yardstick (PY) system - see Merlin Rocket handicap rating.
