POOR MAN'S TECHNOLOGY.

I found this trolley at rubbish bean. Is a bit rust but it works and is strongh enough. Take a look at the bottom, I leave a bit of curvature between the last bulkhead and the transom.
Nobody can doubt this boat is very light. The shape and lightness I was looking for is inspirated in currachs or curraghs of Aran. I hope it works.

STEP ONE IN WAVE POWER PROPULSION DEVICE.

I'm talking about wave propulsion, and this is a perfect machine, made by nature. See the "bottom",  looks like a planning hull. I know some people talks about dolphins and displacement hulls, but a boat have not muscles; springs or rubber ropes are not muscles. I'm not an "expert", sorry, I'm just a beach boy, but my device works.
I suppose the flow of water around a displacement hull is important but not desiderable if is intended to use that flow of water like a propulsion.

BOATBUILDING III.

Don't looks all that bad, I think.

BOAT BUILDING II.

After the rain, some fiberglassing and sanding. Then sanding. And then sanding. After all was perfect, just sanding a bit more.

BOAT BUILDING

Pure backyard boatbuilding. After this stage, three months of continuos rain, as never seen in Spain in forty years.

This is my first design, attempting to develop a wave propulsion system.

DORADO BOAT.

This boat was builded by Ashley Cook in New South Wales (Australia), and designed by Jim Michalak. I bought the plans at Duckworks (see link).

69-year-old Japanese sailor Ken-ichi Horie captained the world’s most advanced wave-powered boat 4,350 miles from Hawaii to Japan, the longest distance traveled by a wave-powered boat and, along the way, show off the greenest nautical propulsion system since the sail.

He does a media of 1.5 knots or so, like two miles per hour, because the weather was excessively calm for that  seasson.

 

Francois Kneider, an inventor who is in his seventies, continues to amaze the people who know him by the number of ideas he has and the innovations he brought to life. In 2005, he focused on building wave powered systems for boats.

This is the first project what I knew. The inventor, is an anonymous who in the 30's reach with this model a speed of 10 miles per hour.
But I think all began before, when the whalers observe the die whales was moving along at one knot or so-depend the waves- when floating.
