About Yamoya

Yamoya is a Bruce Roberts designed Spray 370 Pilothouse sailing yacht. We project managed the build through our own company, providing our own labour where we had the skills, and using subcontractors where we didn’t. The end result, in our opinion, is a beautifully fitted cruising home that is a mix of traditional and contemporary.

The Build

Early in 2003, we decided that I would like (need?) another boat. Looking around there was one Australian manufactured yacht that we liked, but was out of our budget – the Buizen (see it here). The production yacht closest to my requirements was available out of Norway, and would have to be shipped to Australia – the Nauticat (see it here). Either way, our budget at the time wouldn’t allow us to just go out and buy a new yacht.

We decided that we could save to buy the yacht we wanted, which would take us about 5 years.  Or I could re-use previous skills and build us one, which would spread the cost out and take about 5 years. We decided to build. After looking around at various designs, one of the designers offered us a pre-cut steel kit at half-price. He had got the steel cut for a client who then decided on something else, and he wanted it gone.

So that’s how we ended up with our Roberts Spray 370. As for the 5 year build plan? It took us 10 years. That’s what happens when you let other things get in the way.

The Future

Yamoya was launched in November, 2014. Initial plans are to stay close to home (Melbourne, Australia) while we sort out some land-based things and then to start venturing along the Australian east coast. Ultimately we would like to go north to Japan and Russia, and then east to Alaska and Canada. Long term dream is to spend some time exploring the inland waters of the USA, and then on to the Med.
