The beauty of the CAD software is that you can do all the what-if iterations you want and play around with the different design elements before committing to materials. If you're not already using it, the rendering mode that allows you to look at your design and move it around in virtual 3D perspective is pretty fun.
There's still no substitute for actually building and surfing a board that you made with your own two hands.
One design element that might be worth a mention here is the difference between using a pointed nose vs a rounded nose. Shortboards use a pointed nose to fit the front curve with the wave face on a critical drop. You're not going to be surfing surch waves on either of these boards. Even some shortboard builders are blunting their noses because most of us never avtually use the point.
If you look at your 2nd board you'll notice it was a way smoother curve and transition at the wide point - that's because the rounded nose (or the blunted shovel nose that you used on one of your earlier boards) puts the acute curve and adds the width all the way at the front of the board. When you widened the tail block you actually did it by making the curve in the tail block more actue. You can test this out by widening the 2nd "eggy" design you've got there - when you widen the nose and tail blocks you get a softer and smoother curve through the middle than what you get when you have points at the nose and tail.
Yes I love playing around with BoardCad, using the 3d feature and the various control points including prolonging or angling the secondary points,
But the final problem is the lack of experience in shaping and surfing.
for example for draft 1: I wanted originally quite high volume board combined with a short length. I like the wide point forward and found out that a narrow tail usually sinks better into the wave for control and it keeps the board more horizontal during pop up. Addtitionally it should help if your surf more front footed, because you need less pressure to sink and/or control it. I wanted a vee in the tail for easier side to side transition and round rails for hold. I integrated all those features in a quit extreme way.
Usually I would have build it, like constructed. In the next vacation I would bring the board to Portugal and would have ridden it.
And then I would have found out, that it works like intended or not and would have changed something for the the next board to build. Its a hard way going step by step improving, getting new ideas or even new written knowledge (like from here). But after returning from the surf vacation some time passes by until the next.
So if you don't have access to surf regularly, the process is much slower. Thats why I wrote I will never get the final shaping wisdom and see me more as a builder than a shaper. this is why I published the draft here, which led to this very interesting discussion (at least for me), which resulted in hopefully much better shapes, which should better suit for me.
What I already experienced is that all boards, no matter how bad the shape is surf! (Even a door would surf) The question is always how they surf better and how to fit for the particular surfer. And this is where I love the opinions of the experienced surfers and builders!
I have received a nice finetuning of draft one and with your help draft 2 was created. If I got the time I will build both, for comparison and to get more experience and knowledge, but I'm struggling which one to build first. Latest end of May I will be surfing again, hopefully with 2 new boards and hopefully good waves to improve my surfing too.
After reorganized my little workshop I will post the build(s?) in www.woodboardforum.com, where I am one of the founders. If its completed I will publish pics here and link the build thread.
Thanks to all for the support, especially gdaddy!
The guy you need to inquire about building hollow wood boards is Huck, who's a moderator on this forum. He came up with his own method of building wood boards that's killer.
Yes, I know Huck, he is the inventor of the outside rails first method, I think he called it the Bahrmann Rails. He actually is already a member of woodboardforum.com, Inspired by him, I build a 3 piece collapsible hotcurl. it fits into a travel bag. Its an unconventional shape too, but it worked well. I got some decent rides with in Dakar, Senegal Africa and one of my surfteachers there could even noseride it almost.
This is the diary, which tells the Senegal Story:
And this is the build:
