The builder is Steinar Alvestad. He was indeed clueless when he and his brother bought the plans for a 20m/66' harryproa as neither of them had...
Finished boat? Me? It is finished enough to go sailing (needs the plastic beams melted and moulded for the deck slats and a coat of paint), I...
Rael, thanks for the compliments. Couple of things you missed: Harryproas are not expensive. They are cheaper for their length than any other...

Use sheet material to line the frames, then lay the glass, foam and glass in it and infuse all in one hit. No filleting or tabbing and much less...
If you are going to the trouble of erecting frames for a flat panel build and infusing your panels on a table you will save a lot of time,...
The few cruising catamarans that capsize, do so in microbursts or rogue waves, so model testing in conventional wind tunnels and wave pools is...

You understand wrong about 'these proas'. The structural calcs are by a highly qualified and experienced composite engineer. Using first...
I've known Jamie for years, used to steer his F40 catamaran (until we capsized it). Suspect panels was not his choice. See the last line of my...
The comparisons above relate to non CE boats, the type that have been built in Australia and New Zealand for 60 years, without the need for...
