Modified Sparrow

After MUCH playing about with things I now seem to have hit on a winning design planned from the outset to meet our clubs 31” overall length rules. (i.e. almost a RS770 but not quite.)
After three prototypes I’ve arrived at the model shown. Compared to an RS770 she’s slimmer, has more rocker, a much bigger sail plan and modified rigs. She’s pictured with the “A” rig but sails well no matter which one of the available 4 I use. Construction is glass over 3/32 balsa planking with a thin ply deck. Even though I say so myself she sails extremely well and has won almost every race she’s been entered in since completion some four months ago. (We race every week) Named “Loco” mainly because my wife had a new craft die that cut out some pretty locomotive designs she steams along beautifully.

I’d be very interested to sail her head to head against an original RS but I guess I won’t be returning to New Zealand for a while yet so am hoping I can find one in the UK to play around with.
Thanks once more for pointing me in the right direction with your excellent design.
Cheers,
John Goodyear

Hamish's Twin boats

Hi Bryn, I recently finished building these 2 Racing Sparrow RS750s which i really enjoyed, it was a great project and kept me busy for a few months. They have been for a successful maiden voyage and sail great and now just need a few tweaks in the sail department to get them sailing even better.
Thanks, Hamish Coubray, Auckland

Mel Kitson's 750

Hi, Bryn, I enjoyed the build immensely. There were areas where I had some uncertainties, some of which were assisted through the forum posts, and some of which I improvised. All in all I am truly delighted with the end result and now look forward to learning to sail and enjoying many happy hours "playing".

Kind regards, Mel Kitson, Watford UK.
