Zeyang, the guy who took 30 years to build that boat is me, and I'm the guy that suggested a possible welding sequence to you back in post 104 of this thread.
There's more on our boat in the link at the bottom of this post, but I seriously need to update that web site... trouble is I'm too busy building to find the time.
And Bob, I think it's absolutely true that there are 2 types of people who build boats... those who like the process, and those who see the building as a means to an end... going sailing as soon as possible.
The problem is that as you get up towards 45-50', the man hours needed to finish are just about overwhelming for one person who's trying to hold down a good enough job to support a mortgage and a family, tend to that family, and still find the money and at least 25-30 hours a week, 100-120 a month, to complete the job. Half a man hour per pound of displacement is not unreasonable, for a simple build from the ground up, which in my case would work out to 20,000 man hours. But I chose to go far from simple, and have closer to 35,000 hours in the whole job. Finding those hours takes many years. I've only been able to afford paying other people for about 5,000 of them... the rest are mine.
My life was quite different when I started... I knew that it was a huge project but I was making very good money flying airplanes and assumed I could pay competent help for large parts of the project. That income dried up and I found myself a couple of hundred thousand into it, with maybe 4000 hours, and no income. Now what? Just walk away, or keep going at whatever speed is doable? I chose to keep going. It takes so long working alone that everything changes during the process... of course costs go up, but design trends change, needs and wants change, gear and equipment changes, rigs, engines, everything is pretty different now from when I started, 30 years ago. But I end up with a boat I want and know, down to every last detail, and everywhere my eye comes to rest I find something that makes me smile. Plus I spent a very large amount of time on the water during those 30 years, including sailing from Halifax to Grenada, Marion-Bermuda, and 8 35 day swordfish trips to the Grand Banks in the fall.
Living in New England, I feel that boatbuilding is really winter's work, and I developed a schedule that had me going as hard as possible on the boat from late september to end of May, than hang it up completely and spend every possible minute on the water in the season. Worked for me, because burn out is a real factor if you don't get away from the project... you have to just keep breaking it down into smaller sub projects and keep putting one foot in front of the other.
We've been in the water 3 seasons now, and I'm still working... the first part of this winter on a laid teak and holly sole.
My wife would really like a salon table, which we don't have yet, so that's probably next.
So where do I stand? Well it took this long, so I guess you could say that I'm the guy that prefers building to sailing... but once we get our last kid out of college, we'll see. Meanwhile, life has been great, and I don't regret a minute of it. This is a tremendously rewarding and satisfying thing to do, but it's clearly not for everyone.
