The Topper Topaz is a British single-handed or two-handed sailing dinghy that was designed as a beginner and intermediate racer.^[1]

The boat is referred to by the manufacturer as the Topaz System, as the basic hull can be fitted with four interchangeable rig and sail combinations, with the aim of matching performance to sailor skill level.^[1]^[2]^[3]

The design is recognized as an International Sailing Federation (ISAF) Learn To Sail Class and was named Best Dinghy by Sail Magazine.^[1]

Production

The design is built by Topper International in the United Kingdom.^[1]

Design

The Topaz is a recreational sailboat, with the hull built from a Metalicene superlinear polyethylene and honeycomb structure tri-laminate. It has a fractional sloop rig, with a tapered mast, a plumb stem, a reverse transom, a transom-hung rudder controlled by a tiller with a hiking stick and a daggerboard. The hull displaces 60 kg (132 lb)^[1]^[2]^[4]

Topaz Race X: This model has a clear, fully-battened mylar mainsail and jib with an area totalling 8.68 m² (93.4 sq ft), plus an 8.41 m² (90.5 sq ft) asymmetrical spinnaker.^[1]

Operational history

An evaluation published in Yachts and Yachting concluded that the Race X model provides "seriously fast sailing for the club sailor right through to a professional sailor. The asymmetric system is simple, easy to use and easy to rig and takes the boat to yet another level only found in boats costing twice the retail price." About the Tres the report states, "Once the kite [spinnaker] is up, the Tres fairly shoots away. Reaching performance is truly in the apparent wind sailing league".^[1]

In a Sailing World article in 2017, American writer Tim Zimmermann praised the design as the ideal boat for a family with young children learning to sail. He indicated that the boat combines excitement, durability, versatility, is fast to rig and de-rig, "semi-indestructible", affordable and able to accommodate a three or more children, or a child and an adult.^[3]
