Why we don't ship blanks

Every couple of months, someone emails the bay asking if they can buy just the foam — the rough-shaped blank, no glassing, no finishing — so they can finish the board themselves. We always say no. Here is why.

A blank is not a board. It is foam in a board-like shape. The thing that makes a McCallum a McCallum is not the foam, and it is not the outline either — it is the relationship between the outline, the rocker, the rails, the bottom contour, the glassing schedule, and the finishing. Pull any of those out and what you have is something else.

We have shipped a few experimental hand-shaped blanks to friends over the years. None of them ended up surfing the way the finished board would have. The rails got rounded over wrong. The glassing was too heavy. The fin boxes ended up half a degree off. One came back after six months for a re-shape that turned out to be cheaper than what the buyer paid for the blank in the first place.

If you are a shaper looking for a McCallum-style blank to finish yourself: we won't sell you one, but we will tell you what we'd use. Talk to US Blanks; the 6'10E Egg blank is the closest thing on the market to what we shape over. Talk to Surfblanks Australia for the longer mids and logs. Use a 1/4 inch redwood stringer minimum on anything over 7'.

Or — and this is the actual recommendation — buy the finished board. The whole point of the four-tier system is to make the cheapest tier accessible enough that the foam-only argument falls apart. A Mexico-made McCallum costs less than a quality blank plus glass plus your time.
