What our customers say about Racing Sparrow

Being a complete novice, I purchased your book a couple of years ago and built two racing sparrows. Building on this experience I then went on to build, from scratch, an IOM (Triple Crown design).

I've since joined a local club and sail virtually every weekend. I would just like to thank you for your endeavours which have allowed me to enter a world I never thought was in my reach.

John Sterland, Australia

Coming upon your book, "Build your own Radio Controlled Yacht" in the Napier Public Library, I am hugely impressed.

The combination of your superb photos and illustrations with your easy writing style make it a standout publication and I hope it does well for you.

Richard Spence, New Zealand

Thanks for an excellent design in your RG65. I trialled her again today in a solid 20 knots gusting higher. Even so in a steep chop and fingers off the rudder she drove upwind remarkably well, balanced perfectly.

Very impressed that a model boat can handle that with a large rig. I found the book excellent. Ive built several big boats, plus a few skiffs and without that resource building such a good boat would have been impossible.

Hello! Here a couple of pix of my Sparrow. She’s been finished for a year or so now but the lockdowns has kept her out of the water largely.

She’s a beaut. Sails beautifully on just the lightest air. Thanks for the design!

A perfect example of a Racing Sparrow model yacht. The sail plan looks to be exactly to the plans given by the designer. Fantastic lines. The boat is sailing upwind with sails in tight and a 30 degree heeling angle, Location: USA

More about Racing Sparrow

What is Racing Sparrow and who is Bryn Heveldt?

When I was nine years old my father, Ross Heveldt taught me to sail down at Bucklands Beach in Auckland. My wee optimist dinghy was called 'The Racing Sparrow', the nickname my uncle Bruce Curry gave to me when I was a small boy. Apparently I had an abundance of energy.

I studied at Whanganui School of Design and have been a designer / developer since 1998. I live in New Zealand.

Best wishes and happy sailing, Bryn Heveldt.
