The open rules of the RG65 class allow for a large variety of designs to race together. Some are specific to the RG65 class but scaled down IOM (65%)and Marblehead (50%) designs are common. Common designs sailed in the UK are:

Dragon Force 65

Prototype Dragon Force 65 

Mike Weston (RC Yachts), John Tushingham (Graphite) and Mark Dicks (ICE RG65) have teamed up with Ripmax and Joysway to develop an almost ready to sail RG65 - the Dragon Force 65.

The boat is based on the ICE design with an ABS hull, profiled aluminium fin and molded plastic rudder. The rig is a full sized, low aspect RG65 rig with carbon spars and a ball raced gooseneck.

A set of one design rules has been put together to allow the Dragon Force 65 to sail as a restricted class within the RG65 class rules.

The JIF 65 designed by Maximo Lange makes a good introduction to the class. With a simple single chined hull, the plans contain all the details required to put together a kit of parts, including the shapes of the hull panels. The sails can be cut from the full size patterns on the plan. The result is a balanced, easy to sail boat with good internal space and an easy to adjust rig. It dosen't need an expensive sail winch and can be sailed using standard servos.

The plan can be downloaded for free from Marine Modelling International and most copy shops should be able to print it out for a reasonable fee.

Sails, rig and deck fitting kits as well as keel blanks and bulbs can be obtained from PJ Sails


PJ Sails Puma
Also designed by Maximo Lange, the Puma is a round bilged design that is narrower than the JIF65. The result is a hull that tracks well and is easily driven, even in light airs.

The complete plans including building and rig details can be obtained from the Traplet Plan service as a 2 sheet plan but they are also available to download from the French plans archive at  The hull can be planked or a moulded fibreglass hull can be bought from P.J.Sails. A article on planking the Puma hull has appeared in a past edition of the MMI Plans special.

Round Ranger
Round Ranger RG65

A round bilged design from Bill Hagerup in the US, the Round Ranger was available as a vacuum formed hull and deck from Breaking Wind Boats. Unfortunately they have recently stopped production of their plastic hulls. There is a build log at the Weecher Sailing website and in the AMYA Model Yachting Magazine #165 (The Class Association has some spare copies). The hard chine Cobra 5 is a very similar hull shape and can be built using the same mast/keel/rudder positions.
