The RS300 is a modern racing sailing dinghy made by RS Sailing. The RS300 is a one-design, single-handed, hiking dinghy  with a PY (Portsmouth Yardstick, RYA) of 985. Designed by Clive Everest first produced in 1998  it is thought to be based on the International Moth, of which Everest was a successful designer.
Performance and design
There are two rigs for the boat. Rig A is slightly smaller than Rig B. The two sail sizes ensure that the power-to-weight ratio and handling characteristics are similar for both large and small sailors. In Yachts & Yachting magazine in the year 2000, the RS300 has been described as “…one of the most challenging and exciting dinghies I have ever sailed…”, as well as “…the first boat that I have sailed that is a joy just to sail around the course let alone race…” by Steve Cockerill, a renowned dinghy sailor who is past and present UK champion in many classes, including the RS300, Blaze & Laser Radial.
