Hi Bob,
Great model you made!.... Nice details. I have the idea to build the Spray from Joshua Slocum also. After reading all his books, I see Joshua as my hero! I'm a sailor myself and sailing at sea for 30 years . What he did was, in that time, an amazing trip.
After reading his stories I found lots of information about his trips, his boat and a very nice inpressive youtube video. http://www.youtube.com/watch?v=iciZer5cbJ8
So, i desided to build the Spray in scale between 1;10 or 1;15 ( moreless between 73 cm and 1.10cm ) in traditional bent framing method. Many drawings are availible on internet. After several photos I made up my plan in detail. And the Spray must able to sail with RC. So, the structure must be strong enough, mostlikely keperglass and epoxy inside.
For sure I will make photos during the builing and leave some meassages and pics here on the forum.
regards,
Barend
