Learn the Rules Before Playing the Game!

I always say I dont know how to do something until Im done. This is because of a technique that I learned writing software. 

In the olden days (say, the 1980s) software engineers, as we were called back then, would study a problem exhaustively, devise a strategy to solve it, create a rigid waterfall project plan, and engineer a program.

This engineering approach to software development failed miserably. Turns out, building software isnt like building a bridge. Its more like writing music. You start out with an idea and plink out a few notes on the piano. If you like them, you keep them. If not, you plink out a few more and keep going until you have a whole song.

In other words, you start writing the song without really knowing where you are going or how you are going to get there. You confidently proceed as though you know the song will turn out in the end and somehow, magically, it does! At least most of the time.

In the software world, thats called the Agile method, and thats how softwares been written for the last 10 years or so.

From long habit, I used the agile method when I built Cabin Boy. As anyone whos read my Cabin Boy blog can attest, I had no idea what I was doing when I started. I just confidently proceeded as though everything would turn out in the end, and it did!

Cabin Boy on Launch Day how clean!

It even worked when lofting Cabin Boy, even though I gradually came to understand that I had done a really lousy job lofting Cabin Boys plans.

This confident, proceed-as-though-you-know-what-you-are-doing approach doesnt work for everything, though. For example, if you wanted to win a chess game from an even mediocre player, it would be a really bad idea to sit down at the board without knowing the rules, first.

You couldnt just say to yourself, "well, I know how to move the pawns, so Ill just move all of those while learning how to move the rest of the pieces."

By the time you moved half your pawns and learned how to move your knights, the game would be over. Youd have to start a new game from the beginning and try again.

The agile approach doesnt work for lofting a round bottom boat, either. I know, because I tried.

I read a bit in my boat building books (BBBs), but after reading a few paragraphs, I had no idea what they were saying, so I figured, "Well, I know enough to get started. Ill learn by doing and it will all work out, somehow!"

I laid down a few lines (which took hours), but soon reached the end of my knowledge. No problem! I just picked up the BBBs again to see what the next step was.

Whoops! Turns out those lines werent quite right because of something new I learned.

So I erased them, re-drew them with my new knowledge, and got a bit further before -- hours later -- I had to stop and pick up the books again.

Oh, heck! Turns out those lines were completely wrong!

Oh well. Pull out the eraser. More erasing; more drawing; more wasted time...

To make a long story short, it wasnt working. Well, it was, but it would have taken all year, plus a dozen erasers and pencils to finish. Plus my lofting board was only 3/4" thick. It would be thinner than the iPad2 by the time I finished with it.

So I stopped, put down my drawing tools, commandeered the dining room table for a week, and figured out how to loft.

In other words, I learned all the rules before starting the game.

And thats the lesson for today: dont even think about trying to loft a round bottom boat -- even a very small one -- without knowing all the rules, first.

Learn-by-doing doesnt work for lofting. Learn-by-studying does! But I didnt say it was easy! photo jalmberg

Easier said than done, because all of the BBBs -- without exception -- do a really bad job at explaining lofting. Its all there, especially in my Bible, Greg Rossels "Building Small Boats", but its rough going.

I wonder how many people today actually know how to loft a round-bottom boat from traditonal plans, like those of William Atkin?

Lets find out. There are about 1500 people reading this blog on a regular basis. Please rate your own lofting skills. Dont be afraid to say No clue! No one will know its you.



Update: Obviously, I drastically under-estimated the amount of time needed to build a complicated little boat like Vintage! Since there are a ton of things I want to build for the Blue Moon this summer (2011), Ive decided to suspend this project until the Fall of 2011. To be continued...
