Non-surfers and surfers alike are amazed about the amount of work and care that go into shaping a surfboard (aside: surfboards are shaped rather than made).
Here's a video of veteran shaper Terry Martin of Hobie fame. This gives a good idea or the work and expertise that's required.
And this is just the shaping phase! The board has to be glassed and polished as well, and that's an entirely different process, requiring an advanced skill set of it's own.
Now do $1,500 surfboards make sense?
Anywhoo, this is a nicely produced video I found on YouTube; watch and enjoy.
