The BlueMotion-550 (aka BM550) high performance dayboat

Runner-up for the Yachts and Yachting "BEST PERFORMANCE BOAT UNDER 40ft" award 2014.

" This was one of the fastest downwind sleigh rides I've enjoyed for a long time - big grins were the order of the day."

Rupert Holmes, Yachts and Yachting Magazine.

BM550 is a new 5.5m dayboat (or large dinghy) design for 2013. The design is a direct derivative of my Hazardous Zero-9 Merlin Rocket design, and with 19 sq m in main and jib, plus a similarly sized spinnaker, has sufficient horsepower to provide a superb sailing experience, but with the reassurance that the 55kg lead ballast in the centreboard will keep the boat the right way up.

The prototype boat is of cedar strip/plywood/epoxy glass composite construction. This design is being marketed and manufactured by BLUEMOTION YACHTS (Foundry Reach Yacht Sales and Services), who are producing the design in FRP. The prototype was exhibited at the RYA Dinghy Show at Alexandra Palace, London, on 2-3 March 2013. BlueMotion was shortlisted for the Concours d'Elegance prize.

The July 2013 edition of Yachts and Yachting magazine featured a test of the BM550. The boat achieved 9 out of 10 in all test categories. Download a copy of the Y&Y Test Report.
