We had some similar trepidation when we undertook our Passagemaker (take-apart, lug rigged version) build. I am no sort of boatwright...more of a boat-wrong...and had never attempted anything remotely like this in my life. (I, too, had made my living mucking about with computer stuff, seemingly the only thing for which my hands were ever much good.) Turned out that the hardest part was the seemingly endless sanding and getting our less-than-perfect fillets to look good enough. We got better as we went.
The alignment was less difficult than we anticipated. With the lapstitch plank edges and the finger-joint scarfs, it's mostly just a matter of being careful and checking alignment as you go. Seriously, I was the kid who couldn't get a model airplane kit to come out looking right. Glue hates me, wood hates me more, and paint hates me worse. If I can do this, anybody with patience can do one of these CLC kit boats.
I intended to use our Passagemaker more as a rowboat (have a larger sailboat already)--something I could use to get out for a row with little effort and advance planning. The sailing was meant as auxiliary to the rowing and to have something more suitable for teaching grandchildren to sail than a 2900# catboat with a 270 square foot sail, a boom as long as the boat, and a four-part, flesh-eating mainsheet. We chose the lug rig for simplicity and to be able to strike the rig to clear the boat for rowing more readily.
But, you know what? She's turned out to be a much better sailboat than I ever imagined. That lug sail Doug Fowler builds pulls like a mule, once you learn how to get it to set well (which ain't all that tricky, a matter of understanding what makes a balanced lug sail work), and I don't know that the "performance penalty" vs. the gunter sloop rig is as much as people might think. I've been able to achieve steady GPS readings of 4-1/2 knots close-hauled in a good breeze, which surprised the heck out of me, given her short waterline and deep rocker.
Anyway, she's a tremendously versatile little boat, a joy to use and a joy to behold.
If you don't want to sit on the floor while sailing, think about doing something like what I described here:

If you're still worried, check with CLC as to whether they are able to supply "replacement parts" in extremis. I'm betting you won't need any, though. <;-)
