Double spreaders are better and give a lot more control over the mast. Also as drawn the head angle on the jib is way too narrow. This would make for a sail that is difficult to build and not very efficient.
I do not dictate to Jeff what to do. I suggest the changes that I think will benefit the boat and its up tpo Jeff to either implikent my suggestions or ignore them. He does fight for his ideas and I listen. The I fight for my ideas. But it is a team effort with me being the coach and Jeff being the quarterback.
I must say that it has been a real honor working on this with Bob. It has been quite humbling. There has been a steep learning and relearning process. It has been many years since I worked in a yacht design office or built a boat. That office did very conservative designs and I had not tried to draw a modern design. I also have not tried to draw a boat using computer drafting programs. Collectively, this has reminded me how much I enjoy drawing boats, and noodling through the difficulties of drafting a fair, complex curved, object and still end up with the shapes you want to achieve where you want to achieve them. It has reminded me of the time and care, and discipline involved to end up with an attractive object that also sails well.
The whole computer drafting thing has been its own challenge. Olin Stephens was once asked if the towing tank took the creativity out of being a yacht designer. He reportedly replied that the creativity was still there in knowing what shape hull to put in the tank. This is very much like drafting on the computer. I also miss being able to lay my head on the drafting board to eyeball whether a line is fair.
I started this process with a sense of where I wanted to take this design in much the same way that a quarterback has a plan for where he wants the football to end up, namely the end zone.
To continue Bob's metaphor, what has happened behind the scenes is that I will pass the ball in a direction I would like it to go. Bob will make suggestions about how to get there, or reminding me when I am facing the wrong direction. Mostly Bob's suggestions are obviously right, but we have also kicked around ideas where we did not start out in the same place or facing the same direction. The dialogue has been instructive and thought provoking.
Bob has been very charitable with his time and patience. He never started an email, "Jeff you ignorant slut!".
This rig design is an example of something that I have known instinctively for a long time, namely that it is very hard to have enough stability to carry enough sail to perform well in light to moderate air on a boat which is proportionately heavy for its length. But it was only when I began to draft a big enough rig to provide the required drive, that it became apparent that within the limits of the length on deck, you could not get enough sail area without making a rig so tall that you could not have the stability to carry that sail plan. It was only after I had drawn it and Bob had a chance to comment on it, that this issue became more clearly illustrated in a way that had not occurred to me before.
Work progresses, and there will be more to come.
Thank you Bob,
And thanks to all who are following this thread.
